Canon has released the EOS Rebel T4i/650D with 17.92 million image pixel. The follow-on to the Rebel T3i/600D adds a touchscreen rear LCD, promised smooth,faster 5fps burst rate, a built-in stereo mic and precise monitoring autofocus while in video record . The new digital camera’s other features are actually much like its predecessor rebel t3i. You can see the detail comparison about t3i and t4i: Click Here.
The followings are all Canon EOS Rebel T4i new features:
1, Thanks to the touch screen, some of the things that you can do include pinching to zoom, pressing to select, and swiping between pictures. Because the screen is capacitive, you can expect the same responsivity that you know from smart phones. The triggering option that is built into the touch screen allows you to take a picture of a particular portion of the screen when you long-press on that portion in Live View, by allowing that area to come into focus.
2, Capable of producing 17.9 2 million pixel photos thanks to its 17.3 x 14.9 COMS sensor, the T4i is not very different on this account from its predecessor the T3i. The only difference is because of the AF detection in its center portion, autofocus performance is greatly enhanced both in Live View mode and video capture mode.
By coupling the embedded phase AF with the contrast detection, Canon gave rise to its Hybrid CMOS AF technology, making it the first SLR camera that has an AF sensor built into its image sensor. This makes it far more powerful than the primitive J1s and V1s that Nikon released last fall.
3, The T4i takes both EF and EF-S lenses. A full-resolution image is 5184 x 3456 pixels. The focal length cropping factor is 1.6x, in accordance with a full body digital camera.
With its 5fps continuous I-frame per second shooting, 30 Large/fine JPEG option, 3 RAW+JPEG option, or 6 Raw, the T4i have actually been downgraded in this regard from the T3i. The camera has one memory slot that can take an SD Card, a SDHC card, or a SDXC card. Another excellent thing about it is that it supports Eye-Fi and is the first camera Canon has produced that makes use of the fast HIS-1 read/write speeds of select SGDHC and SDXC cards. This clearly observed when you use a slower, nonn-UHS-1 card.
4, The sensitivity range is ISO 100-12,800 in 1/3 step increments, plus H (ISO 25,600).
5, All cross type points are supported in the 9-point AF system, same as the EOS 60D. Higher precision can be obtained from the camera if you use an f/2.8 or faster. On the other hand, if you use a slower aperture lens, you won’t be able to make full use of the AF point detection.
6, The same 63-zone TTL flash metering and Ambient flash metering can be used as in the T3i. When calculating exposure, information is utilized both from these and the 9 AF points.
7, Some of the latest shooting/processing features to be available in camera include the ability to combine 4 high ISO images into a multishot image with minimized noise. If you have a great deal of colored speckle noise, then this will do wonders for you in minimizing it.
8, As to its video capabilities, the T4i is capable of shooting at 30 frames per second at a resolution of 1080p full HD. You can either use the internal stereo microphone or an external microphone that is connectable through a 3.5 mm jack. Both manual and automatic exposure modes are available. Formats supported are H.264 and MOV, with a maximum file size of 4GB. The resolution and frame rate options are:
- 1080p: 1920 x 1080 pixels at 30fps (actually 29.97fps)
- 1080p: 1920 x 1080 pixels at 25fps
- 1080p: 1920 x 1080 pixels at 24fps (actually 23.976fps)
- 720p: 1280 x 720 pixels at 60fps (actually 59.94fps)
- 720p: 1280 x 720 pixels at 50fps
- SD: 640 x 480 pixels at 30fps (actually 29.97fps)
- SD: 640 x 480 pixels at 25fps
9, One of the most remarkable things about it is that the T4i is the first SLR Canon camera that is capable of continuous focus in video. This is thanks to the revolutionary Hybrid CMOS AS system. By using the Movie Servo AF, you can track in video mode. The feature works with any EF-S or EF lens which supports autofocus, but according to Canon, for this quickest, smoothest performance possible, you should use the newly released STM lenses mentioned above are because they are capable of using stepping motors for continuous focusing.
