The New Canon EOS Rebel T4i DSLR


Can you create a rebel or are they just born that way? Obviously, Canon believes they are created and has brought forth its fastest, most sophisticated Rebel to date: the EOS Rebel T4i DSLR. Digital Rebels have always been great Canon cameras for any level of photographer, but this latest model brings with it speed, high-resolution quality and… more speed.

Equipped with an 18.0 Megapixel CMOS sensor, with the same new technologies found in high-end professional cameras, the Rebel T4i produces large, lush images with exceptional clarity and tonal range. These high-resolution images retain their clarity when cropped for details or enlarged into spectacular prints and 14-bit analog-to-digital conversion with 16,384 colors per channel ensures that details and color subtleties, in water for example, are preserved and recorded. For this model, Canon has included an extended ISO range of 100-12800, expandable to 25600(H), which will improve fast action capability and allow for low-light shooting opportunities never before possible.

The T4i also features Full HD Movie recording with the same ease and speed of its still photo capture. Capable of shooting in a number of recording sizes and with manual control of exposure, focus and Live View features, this camera offers professional video quality with simple control. As speed is the calling card of this Rebel, its Video functions are no exception. The fantastic new Movie Servo AF allows continuous autofocus tracking of moving subjects while recording video. This is a game-changer: no more cutting to refocus, or accepting blurred images when someone moves within the frame. All your videos can have sharp images throughout and the built-in stereo microphone means the audio quality will match that of the image. A wind-filter feature cuts down on noise when shooting outside, and recording levels can be controlled automatically or manually. If your recording needs call for the use of an external microphone, a 3.5mm input microphone jack is included as well.

Accompanying the new Rebel into the arena are two lenses, as part of two separate camera kits. The first is the 18-55mm f/3.5-5.6 standard zoom lens, a go-to lens for all your day-to-day needs, but the second is a wonderful new 18-135mm f/3.5-5.6 STM Autofocus Lens designed with videographers in mind. The essential features of the STM are its continuous autofocus system and Dynamic Image Stabilization; both features are ideal for shooting HD video. This lens is a wonderful, multi-purpose lens with a long focal range (28.8-216mm in 35mm format) that can be used for almost all of your shooting needs, but has been designed with attributes to make it ideal for HD video work.

With the new 18-135mm f/3.5-5.6 STM Autofocus Lens, Canon has refined its optical Image Stabilization system within the STM to deliver four equivalent stops of shake correction throughout the zoom range.  And while maintaining its compact size, it can now offer a maximum magnification of 0.28x at the telephoto end. Autofocus speed has increased due to an Inner focusing system, a high-speed CPU and an improved AF algorithm. It also added a zoom ring lock to prevent the lens from accidentally extending.

But what really marks this lens as a breakthrough is how it’s designed to work with the Rebel T4i to shoot HD Video. Specifically, the lens syncs with the T4i’s Movie Servo AF feature to provide a smooth, quiet and continuous autofocus when shooting movies. The camera re-focuses while you shoot, and the smooth transitions and quiet operation mean no erratic fades and jumps when subjects move, and no whirling sounds of the autofocus cutting into your recorded sound or dialogue. For those who desire a DSLR to shoot high-quality video and still have photo capabilities, this is the camera and lens system for you. The continuous auto focus operates thanks to a new six-group zoom system and the utilization of a stepping motor and focus mechanism. Taking DSLR movie capture one step further, Canon has introduced Dynamic IS (Image Stabilization) to this STM lens. This feature only functions in Movie Shooting Mode but uses a wide image stabilization correction range to ensure steady, shake-free video, even when walking while shooting.

At the heart of the T4i’s excellent image quality and high-speed functions is the powerful DIGIC 5 Image Processor. From the 9-point cross-type Auto Focus system to the expanded ISO range and the continuous shooting of up to 5 frames per second, the DIGIC 5 processor puts fast action capture and low-light capability into the hands of any photographer.

To further enhance the all-important auto focus on the T41i, Canon has adopted two systems, which in combination have markedly improved the AF’s speed and handling and will eliminate that horrible feeling of seeing the action pass by as your camera rolls and hunts for its focus. A 9-point all cross-type AF system (including a high-precision dual-cross f/2.8 center point) will quickly lock in on what you are shooting and retain that focus and a new Hybrid CMOS AF System increases autofocus speed and accuracy when shooting both photos and video in Live View. This is a hybrid system because it incorporates both phase and contrast detection AF technologies and is a CMOS system due to the pixels on the sensor that can assist in predicting a subject’s location and therefore track and focus faster.

As mentioned earlier, image processing improvements have increased the Rebel’s continuous shooting speed to 5 frames per second, so between its lightning-quick autofocus and rapid click, click, click, you will not miss the action, whether it is your daughter’s first goal or that simple turn of a smile that captures your son’s true beauty. Memory card compatibility has also expanded to include the Ultra High Speed (UHS-I) memory cards and Eye-Fi SD cards, which contain a Wi-Fi transmitter and internal antenna for wireless uploading of images directly from your camera.

An additional component new to the Rebel series is its Vari-angle Touch Screen 3.0-inch Clear View LCD monitor II. This rear screen, tiltable, rotatable LCD brings a level of ease and speed to what is arguably the most important part of your shooting experience: composing and playing back your images. The Vari-angle design will also allow for faster overall shooting as you flip out the screen and twist it to any position that is most comfortable for getting your shot. No more maneuvering the camera out of the glare or squinting to see your composition. It’s wonderful for shooting in a less conspicuous manner too—quick as your hand can move, get the genuine smiles the first time, no need to ask everyone to pose again. This large, bright display is also built with the same touch-sensitive technologies of the latest smart phones. It delivers intuitive touch-panel operation that can be used for zooming or changing images as well as navigating menu and control settings. A new construction between its resin-coated cover and the liquid crystal display reduces reflections and glare, and its Clear View coating minimizes smudges and fingerprints, allowing you to enjoy the details of your images on its 1.04 million-dot screen.

It’s a good time to reiterate that the EOS Rebel T4i DSLR is available in two distinct kits, one with a lens that, while great for still photography, has been refined and specifically designed to shoot video. The first kit matches the Rebel T4i DSLR with the classic Canon EF-S 18-55mm f/3.5-5.6 Autofocus lens. This is the standard, good-for-everything lens that was designed specifically for the Rebel’s APS-C sensor. Its focal length is equivalent to 28-90mm in 35mm format which means you can go from wide-angle to telephoto in just a quick turn of the ring.  It features Canon’s Optical Image Stabilizer technology which compensates for camera shake to give you crisp, blur-free images every time.

Of course, the T4i is compatible with the full line of Canon EF and EF-S lenses, but this Rebel has been created with a partner in mind: the new EF-S 18-135mm f/3.5-5.6 IS STM Autofocus lens. This lens is a wonderful, multi-purpose lens with a long focal range (28.8-216mm in 35mm format) that can be used for almost all of your shooting needs, but has been designed with features to make it ideal for HD video work.

Simple, fast and fun, that’s the Rebel. Improvements in image processing, autofocus and noise reduction have increased the T4i’s capture speed and image quality and its Vari-Angle Touch Screen offers flexibility and the simplicity of touch technology, but there are a host of creative and fun features that enhance this camera’s shooting experience. Scene Intelligent Mode will incorporate all the camera’s meters and do everything but push the shutter button for you. Handheld Night Scene Mode and HDR Backlight Control Mode combine multiple exposures into one image in order to retain the details in both highlights and shadows. Photobook Setup intuitively sequences your photos for printing or sending. GPS compatibility allows you to mark location and metadata right on your photo and seven creative filters give you in-camera Photoshop-like features to create eye-popping works of art from your images. With its notable improvements and renowned Canon design, this new Rebel is ready to push its way to the front of the line. It can be your entryway to creative photography.

Can I use the Roland F-1 external Inuit via USB to record video my camera while also plugiing in an xlr microphone to record audio?

I need to include a date stamp on my videos. before I switched to the T4i I used a small app that stamped each frame. Now with the Canon format, the app does not work and I have been unable to locate another method to accurately including the date in my work.
Can you help?
Do you have any suggestions?
Thank you for the suggestions for monitoring the audio. This was also a problem.

Dave B

Hi, can someone tell me what I need to monitor audio on live recording. I have seen numerous articles about Sescom audio monitoring cables but nothing clear about this model.

I use a Rode mic but notice in only have a A/V out USB socket.

HELLO? Mic? Audio Input? Mic Input? I don't understand how you could list such detailed specs and yet not mention mic input specs? At what level? For condenser? Dynamic? Mic input impedance? Am I missing something? Is audio not important? Video people focus (pardon the pun) on video and forget audio, as if it's not important.

What an excellent and very informative article. I have now owned my T4i camera for over 8 mos. and absolutely love it. This is an upgrade from a sony S1is which was a nice transition to this one. I am having a little difficulty with trouble shooting the microphone setting. I just purchased a Mega Gear, shot gun mic. I attached it, placed in the batteries and turned it on. I plugged in the adapter and immediately shot some video. After speaking at a normal voice I played back the video only to have the audio to be almost non existent. I checked the connections and made sure everything worked and then pulled out the manual and found the section on rec level p173? I then was able to set the meter for the mic and moved the little arrow to the right so it was right on top of the 12 that is displayed. The manual said something like move the meter so that the meter increases in volume and something like a -12 for loud noises but going too far to zero may cause distortion. I apologize for not getting it exactly. I am pretty sure that my error is some how connected in this area. I also noticed upon moving the setting to the right, that I would see the meter levels jump one notch. these are located just beneath where my adjustments are and they are Horiz. Should these be jumping a lot further to the right to indicate I am correctly increasing the volume? I know it will be trial and error but was looking for a little insight. Oh, the setting is M for Manual. I thought I had it fixed and upon shooting more video the volume was no different. Thx in advance.

i just bought a t4i kit 18-135 ef-lens stm , when i chose auto focus. the lens does not move like my 18-55mm ef lens does. so i wonder that the stm lens broken or this just a new technology

Would the STM be the best for videoing birds in flight? If not, what would be under the $1400 mark. I am planning on using the STM but concerned that I can't focus the lens to infinity and worried the AF won't focus on solo birds stuff in the background when panning the camera to follow. Adding a follow focus is paramount for me as I'll want very smooth zooming. This is my first big camera purchase and I like the cost and features on the t4i but worried about lens set up. It's also worth noting that low light conditions will be a regular occurrence.

Thank you for answering my questions in advance and I look forward to hearing from you soon.


HELP!!! I took a bunch of pictures of my sons baseball game, turned the camera off for a minute to conserve the battery and when I turned the camera back on, it said "card cannot be accessed Reinsert/change the card or format card with camera" I'm afraid to ask where are the pictures I took on the card. It's an 8gb card and I know I should have plenty of space. I know my pictures were saved on the card prior to me turning off the camera because I previewed them. How can I retrieve the pictures from this memory card??? Please tell me I did not loose them!!! I haven't formated the card because it said it will delete everything on the card and that's not what I want. Please help!!!

Unfortunately it sounds like the data may have become corrupted. This can happen for a few reasons but if the camera was turned off when the files were still writing to the card that is the most common way.
You will need to bring the card to a data recovery center to try to have the files retrieved. If you are in the NY area, I would recommend contacting:

I just purchased a T4i, received it in the mail yesterday and opened it. After taking a few pics I turned the camera off and went to bed. Getting up this morning and turning the camera on I find the same error message. The camera is brand new, could this be a defect in the cameras or faulty cards?

Just to be clear: Does autofocus work when using Full HD video with the EF-S 18-55mm f/3.5-5.6 Autofocus lens OR does video autofocus only work with one of the STM lenes?

Does it record timecode like the latest 5D?

Hi, I'm looking to purchase the canon 650D with a two lens deal currently available on some website "Canon 18-55is II& 55-250IS II Lenses". Are the two lenses good quality, or am I better to buy the camera body and seek better lenses separately. If these lenses are sub standard, I get a good deal but give away quality....



I could not find any information about the remote shooting.
Is it possible to remote control (focus and shoot) the camera from the PC with the included solutions software?

I am a little disappointed about the camera battery life. But I get the touch screen and AF came at a price.

Hi there,

Can anyone please tell me if it is possible to record with a fixed bit rate of 35 or 50mps? Or is this something I would do afterwards when converting the files using AppleProRes?

Some cable channels require that the files be 50mps. The new Sony PMW-100 can record with such high bit rate; my EX-1 only goes up to 35mps.

I see variable bit rate, with filetype .mov /h264 rather than MPEG-2 or MPEG-4.

Can anyone enlighten me before I purchase it? Thank you so much!

Hi, I know the audio levels on this camera can be manually set, however can you set both left and right channels at different levels? Or is it just one level that is set for both left and right channels?

I am considering trading in my T2i for a new T4i primarily because I want to be able to take more still photos in the "continuous" or "burst" mode (shooting action wildlife).  My T2i is rated at 3.6fps and the T4i is rated at 5fps.  5fps is probably fast enough.  I am more concerned about how many shots I can take continuously before the camera must stop to let the buffer write enough data to the memory card to create room for new photos.  In other words, I need a longer "burst", not necessarily a faster one.  I am currently using a SanDisk Extreme card that is rated at a "write speed" of about 30Mb/s.  I want to know whether I will get "longer bursts" with the T4i if I buy the SanDisk Extreme Pro (rated at about 90Mb/s).  Would the faster SD card let the camera's buffer clear more quickly so that it can take more shots before it must stop to let the memory card catch up?  I think that what I am asking is:  (i) what is the "write speed" of the buffer in the DIGIC 5 processor (writing RAW format, not JPEG), (ii) is the throughput speed of data from the CMOS sensor through the buffer to the memory card greater than 30Mb/s (so that it can take advantage of the higher memory card speed), and (iii) how many RAW (approx 18MB RAW images) could the camera write to a 90Mb/s Sandisk Extreme Pro 8GB card before the camera had to stop taking photos to let the memory card catch up with the buffer?


How many continuous minutes can this T4i shoot video with say a 32 gig or a 64 gig card, like for a 

school event ? 

This will determine if a LOT of School video folks will go for this model.  Thanks.

Whereas some other DSLR's have a 12 minute limit and some have a 20 minutes limit the T4I's limit is just under 30 minutes of record time before it needs to turn off momentarily.

Thanks for the write-up. One thing not discussed is whether you can now shoot stills silently in live mode composing via the viewscreen, like a mirrorless.
(The current rebels must flip the mirror down and up, making a terribly loud clatter. Too noisy for classic music halls.)

I am moving up from a G11, which is my first digital.  I was an avid film photographer and print my own at home.  I mostly take pictures of my grandchildren and landscapes.  So far I have not taken video, but I might want to in the future.  Would the T4i be a good choice or should I stick with what I was looking at --the Canon 60D.  If the T4i is best choice, which of the two lenses makes the most sense for me.  I assume the pancake lense is not needed by me based on comments I have read so far.


about accessories like the battery grip i have to wait till they bring a exact one for this camera or its compatible with the t3i one? 

thank you.

I can find no mention in the specs of the 3x Crop Mode that was available in the T3i and made it a super DSLR for long range wildlife recording.  Has it in fact been dropped from the T4i.

No, the T4i does not include a digital zoom like the T3i.


Can you please tell me if the  EOS Rebel T4i DSLR. Digital Rebels can film in 16.9 F H D or in hd? and the EF-S18 135mm  f / 3.5-5.6 is STM Lens  Do i still need the pancake as well???

PS: i'm going overseas very soon & i need to film 18 hours of footage for community tv, does this camera / lenses do the job??? & what's the biggest capecity of sd card i can use??? Battery's!! filming in FHD what's the battery life??? do you have bigger memory batteries than the one you supply with the camera???

Does this camera has socket for a headphone??? Does this camera have facilities to use ext mikes???

I'm waiting for your reply please A.S.A.P.cause decision have to be made by the board, to purchase 2 cameras,  beetween this camera & the GH2 LUMIX PANASONIC...Does these cameras available right now???

Your Honest Oppinion Much Appreciated Please...

Kind Regards

Joe Borg


The Rebel T4i can record video in 16:9 aspect ratio at 1920x1080 full HD.

The EF-S18 135mm  f / 3.5-5.6 is STM Lens is a great all purpose lens. The 40mm f/2.8 will only benifit you if you need a lens for low light shooting or need the very small size for carrying around with you.

There is no battery consumption rating for video capture so I would bring plenty of spares as Live View operation uses alot of power. At Full HD a 16gb card will hold 48 minutes of video.

The Rebel T4i is compatible with SD/SDHC/SDXC memory cards.  While Canon does not list a restriction, any currently available memory card should work.

There is an external mic jack but no headphone.

The T4i is currently not available with no expected delivery date.

I know that I am repeating a couple of questions here but I still can not find the answer on the specs list from B&H or Canon...



All the specs seem to indicate NO.

Can some one please clarify?



The Canon T4i does have a 3.5mm microphone input jack but does not have a headpohne jack.

When does Canon start shipping these cameras?

Canon is permitting us to accept pre-orders on the camera, but theres no sense of how long it could take to fulfill your order should you place your order today. I am sorry that we have no specific information provided to us from Canon as to how long it may take to fulfill. 

thanks for the very thorough specs.

The write up waxes endlessly about how great the cam is for video... and then mentions zip about audio control.

Two basic questions every photographer/videographer using these dSLRs for video wants to know:


2. Is there an external microphone jack? (Another poster asked this Q and you answered it).

The Canon EOS Digital Rebel T4i DSLR camera does not have a headphone output connection; however, it does have a microphone input connection.

Canon's menus are simply horrible: The camera has lots of buttons to adjust exposure, ISO, flash.. But unfortunately almost all functions are locked if you aren't in manual mode.

For example, if you are in portait mode and simply want to adjust exposure, forget it!

On other situations, if you want to disable flash auto firing, forget it!

If it can't focus properly or if the conditions are not all correct, it simply doesn't take the picture, if it was The Moment, you lost it.

No in-camera HDR, no in camera panoramic, no nothing. Simply same firmware they have been using over the last decade. 

I'm guessing this Rebel will have the same interface which is unfortunate. For this reason alone I'd opt for one of the D models. I pretty much decided to shot entirely in manual mode years ago... Give me easy acces to change the shutter and aperture easily while looking through the lens and I'm a happy camper. It almost seems as if the controls on the Rebels have been artificially dumbed down. It's really noticable when I go from my 5D to a Rebel- yuck! Pity. I do like the reposition able view finder. I do a lot of low level wide shots and this would allow me to better control the focus. This might be a handy 2nd body if the video and focusing work well 

It would have been nice to hear more about the creative filters that the article very briefly mentions. Are they exceptional or just the average rubbish most camera companies include in their cameras? I'm patiently waiting for some camera company out there to create a real digital camera that allows a lot of image manipulation filters in camera like the amazing Hipstamatic camera. Something even more variable with high quality components and sensors that allow the photographer a range of interesting possibilities in the field. The idea of in camera film type, grain, effects, and creative lens aberrations along with user memory and ability to share it all with other users via the net is the basis for a true digital camera. Where is it? I use my Hipstamatic way more than any of my higher res cameras due to its amazing ability to create transcendence. This should not be something exclusive to a low quality phone camera.

I'd always advise against using any in-camera image manipulation. Heck just converting raw to Jpeg is more than I can stomach. The reason you don't see more of this type image manipulation features is they are basically crap. They are more suited for camera phones as a quick and fun way to share snap shots. To do image manipulation with these size image files you really are better off with a post processing application... I'm pretty sure the calculations would absolutely crush the poor processor in your camera.  I recomend Adobe LightRoom. It can make bad pictures tolerable and good pictures great. 

I'm interested in the real-time HDMI output of this camera. Do you guys know if it does 720p when an external or onboard reference monitor is plugged in?

The T4i has three video recording sizes, 1920 x 1080, 1280 x 720 and 640 x 480. It will display each of  these sizes on the LCD and the external display at the same time even while recording.

Do you mean it will output HD signal via HDMI while recording, as well as keep the LCD running as well?  Do you know if it has a clean HDMI output (no characters on the screen)?  Are you positive it's outputting 1920x1080 HD while recording?  Thanks. 

Is there a headphone jack ?


No sorry, there is not.

So what is the headphone solution?

I am considering this camera for short doc films and like to use a headphone to listen to the audio while conducting the interviews?

So with the T4i can a filmmaker/videographer use headphones?

Is there an adaptor of some kind?


The main The main differences:*The XSi has more mpxeaigels at 12.2MP while the XS is 10.1MP.*For JPEG, the XSi can continuously shoot at 3.5 fps while the XS can do 3.0 fps. fps.*The LCD monitor of the XSi measures 3.0 inches while the XS has a smaller screen at 2.5 inches.*The XSi has a 9-point AF system while the XS has only a 7-point.*The XSi has Spot metering while the XS does not.*XSi's RAW is 14-bit while the XS RAW is 12-bit.Often you'll spend less than $100 extra for alot more in XSi

I have the New Canon Speedlite 600 EX-RT and I would like clairification Will this camera transmit a signal to my new flash to fire when the flash is off the camera ?

I could be misreading the specs because it sounds like the camera has the transmitter built in ?

I really, really want to know: Is this camera compatible with the Canon 600EX flash, and if so, can it be used wirelessly (especially radio-wise) off-camera? Please let us know. Thanks in advance for your response.

On any Canon camera, including the T4i, you will need the ST-E3-RT Speedlite Transmitter or another 600EX-RT on your camera in order to wirelessly fire a Speedlite 600EX-RT.  No camera's have the transmitter built in.

You can use any canon speedlite with this camera off the hot shoe but as it's fired through cameras flash has to be line of sight.

so 40 degrees either side of lens and between five to ten meters range

see owners manual page 200ish.

Did I miss the bit about whether the camera has Aux audio input or is it just the onboard mic for all audio?

I cant believe they wouldn't add a jack input but I dont see it listed.

Hello Kelvin -

It looks our oversight.  Thanks for picking up on this. The Canon EOS 650D T4i has a stereo 1/8", 3.5mm external microphone input port for audio while shooting video.
