Choosing between Sony SLT-A57 and the Canon EOS 650D (aka Rebel T4i, aka Kiss X6i).

Choose between the Sony SLT-A57 and Canon EOS Rebel T4i [/ b] (American name Canon EOS 650D).

Both camera worthy of attention, both in absentia like me. Choose a plan

with pleasure, slowly (two to three months), with feeling, really, with the arrangement. Buy

plan in the United States (as if Canon, it is only with the label Rebel T4i, if Sony, it is only the American NTSC version with 60fps).

One of the most important criteria in choosing considering the quality of the implementation of the function of the phase autofocus while shooting video.

a little free time, so I would appreciate any useful links and information on the topic.

small comparison of the characteristics of cameras based on the specifications posted on the official website Canon and Sony :
1) At Sony A57 - 16. 1 million effective pixels from Canon Rebel T4i - 18. 0 million effective pixels . The difference in the number of pixels does not matter.
2) At Sony A57 matrix size 23. 5 X 15. 6 mm at the Canon Rebel T4i - 22. 3 x 14. 9 mm, the difference in the size of the matrix is ​​not critical.
3) At Sony A57 electronic viewfinder with a resolution of 1, 44 megapixels (covers 100%) at Canon Rebel T4i pentamirror (covers about 95%). I wonder what type of viewfinder convenient and comfortable to use.
4) At Sony A57 15 points avtofuksirovki (including 3 crusades) at Canon Rebel T4i 9 AF points (all crusades). Interestingly, one accurate and stable focus.
5) Maximum speed shooting at the Canon Rebel T4i stated in 5 frames per second (buffer of approximately 6 RAW), at the Sony A57 - 12 frames per sekndu (buffer about 21 RAW). E., The claimed rate and buffer size at the Sony A57 is significantly higher.
6) Built-in flash Sony A57 covers focal lengths from 18mm guide number - 10. Built-in flash Canon Rebel T4i covers focal lengths from 17mm, the guide number - 13. Charging the built-in flash for both cameras announced about 3 seconds.
7) At Sony A57 image stabilization when shooting photos and video realized by shifting the matrix in the chamber itself, at the Canon Rebel T4i presence of stabilization in the camera itself stated, in order to stabilize the image you want to use special stabilized lenses. At first glance, the stabilization due to the shift of the matrix is ​​a major advantage of the Sony A57. I wonder, however, how such stabilization will heat the chamber and thus affect the time video recording.
8) Sony A57 allows you to write FULL HD (1920 x 1080) video in AVCHD (codec H. 264) with a maximum frame rate of 60p (NTSC US version) or 50p (PAL Russian version), declared bitrate - 28 Mbit / s. Canon Rebel T4i allows you to write FULL HD (1920 x 1080) video format MOV (H. 264 codec) with a maximum frame rate of 30p, declared bitrate - 44 Mbit / s. Both cameras write video with stereo sound
9) Both cameras available phase detection autofocus when using LV and when shooting video. I wonder where this feature is better.

- I 60d and A37. We can assume that your option, that is. To. The image and the matrix are identical models 600d and A57, respectively, the only difference is in ergonomics.
As the owner, I can say the following:
1. whale optics significantly better in kenona, it can be removed and replaced sonevskuyu to something more acceptable necessarily
2. Precision BB Sonia above, but kenona accurate tonal transitions and, in the correction BB, the color better. If you do not adjust, color Sonya looks more natural. On average, it turns out: Sonya color more natural, in kenona more beautiful.
3. visual detail in kenona above, even if Sony put a good lens, I think that it depends on the processing intrachamber

For me, the main advantage of the Sony is a natural color rendition and EVI. As a system, I prefer canon, technically it has more features, better choice of optics, costs as a result of cheaper, better technical support and service. But sony picture for the year and she had to get used to me too much.

20.07.2012 9:47:00

EVI better JVI, t. To. Displays what the camera sees, unlike JVI that displays what you see. Video
better in Sony, Canon 600d have no AF. And like a cross AF sensor there only central. Specifically
of these two models with the A37 better nekitovym lens, for example 18-135.

- a good option, but it's just a whale. Sonya finally appeared normal (I hope!) Whale. Already in some stores this set is seen for sale at a price of 28 to 33tr. 28tr for this delicious option.

better parrots. Nexia kit for 55mm - 2442/2081 (center / edge), and in fact the entire 2023/1659.
that much more than the difference between 12 and 14 MP matrix is ​​used in the test. (A700 vs NEX5).
and tests show soap examples (although it may be due to poluzerkala).

You do not understand the question. Better than nothing (not in any parrots), and better than anything (more than a whale).

Test a little success. A little later we shall cut pieces and lay out. Samsung failed the test (the camera's fault). I photographed the library building from a distance of 15 meters. The sun was right behind him.

21.07.2012 19:32:00
Took a few pictures with canon 18-135 whale and Sonia with sigma 17-70. Come to the city - lay, now online only in text mode works.
Under these lenses receive an average parity, if not to take into account some special features. Accuracy of tonal transitions, as I said earlier, kenona better, but Sonkin color I sunk so unique choice for me at the moment does not exist. It's all in advance, because look at the TH-kyo. The final conclusions will be after watching the big calibrated IPS.

Then

22.07.2012 10:47:00

whole point is that the Canon EOS 650D when shooting video FA now too.

rumored sort dachtiki placed on the matrix.

Although the Russian official website is written verbatim :
quote:
semitransparent mirror-speed type (Transmission / reflection 40: 60, the image is not cropped edges of mirrors with lenses 600mm f / 4 or less)
Apparently this conclusion Russian translators made on the basis of this sentence here from the official site www. canon. com
quote:
Quick-return half mirror (transmission: reflection ratio of 40: 60)
How Russian translation corresponds to the original can (if you want) to explain (he speaks English well).

22.07.2012 11:03:00

Yes, indeed realized in the matrix. . . Well anyway, younger models Canon no ice. Sonia video is any better, and Fota at least as good (in-class). Well, plus all sorts of buns from Sony. . . In general, the initial segment of Sony pleases me more and more.

22.07.2012 11:43:00
Why is everyone so happy FAF in movies? I tried, as it runs, and the tests were - FAF video has the disadvantage that runs on the point, and not on the field, and only works when the hole 3, 5 (it automatically opens) resulting in movement of the focus frame have twitching, which means the frame in the trash. On manual focus camera result in much better. Camcorders with its frame CAF estimate more accurately and more depth of field there, so focus smoothly and accurately, thus quickly, but without dergotni.
Regarding kenona literally says, "quickly returns poluzerkalo"
This means that it still goes on in photo mode and up; in the video does not rise. Canon in this regard Sonia covered, as the bull sheep, very well done. It remains to make a qualitative and technological EVI victory will be complete. Anyway, Sonin problems with how clean poluzerkalo have kenona not: for photo let it be completely dirtied - no effect, and video with a resolution of 8 times lower than the photo, fine dust does not matter.

22.07.2012 12:08:00

Why is everyone so happy FAF in movies?
Because quickly and conveniently. I've already laid out example of the AF in video A55. And then, no one stops to shoot video in manual mode.

I do not understand why half mirror is translated as translucent. It is necessary to read the entire text as a whole, but to be honest - laziness.

22.07.2012 12:24:00
Here
interpolation probably played a role. Permission from the different cameras: canon -10Mp, Samsung - 14MP. In kenona still seems a bug with metering (icons and modes do not correspond to reality), but still no way to put avtoISO. In general, such a mess cook.
If possible, repeat the test.

PS No one wanted to offend or hurt.

22.07.2012 12:37:00

why half mirror is translated translucent
- because it goes on to say that the reflection coefficient of 40: 60.
They just put it simply, wrote "poluzerkalo", but the point is clear.
By the way, it follows that no sensor FAF on the main matrix is ​​not, it is usual.

22.07.2012 12:40:00

Something there is about the mirror I found nothing. There is mention about the hybrid autofocus, then on the matrix sensors are present.

22.07.2012 12:56:00

Ah, then it is understandable. Ceteris paribus win megapixels. Sorry
Sony this year will not release in the lower segment that is more than 16mp have to wait another year.

22.07.2012 13:05:00

There is mention about the hybrid autofocus, then on the matrix sensors are present.
- This means that while there FAS through the mirror and CAF through the matrix. Canan again offered the best solution, Sonia KAF not.
sensors are not needed in the matrix, and the reference was that the matrix is ​​the same as in the previous models.

22.07.2012 13:11:00
Translation is still incorrect, in my opinion.

Where you read about FAS sensors on the main matrix? - This is repeated many times, but only as an assumption of readers, not more. As you can see, these sensors are not needed, why do their canon?
In any case, to confirm or deny these things can only official information, but its not on this issue.

why you have decided that I only write about myself? You know for sure. that no one else there can not be of the same opinion?

If not difficult to cite the references, where suddenly I read inaccurately. I still wonder why the phase sensors and through the mirror and on the matrix odnovremennno.

22.07.2012 14:23:00
Well dprevyu really given hybrid tsmos. Perhaps there for video only. And for the old photos through the mirror.
 

22.07.2012 14:39:00
Found, but not in the AF: new "Hybrid CMOS" sensor that now includes pixels dedicated to phase detection autofocus. This
or error, or it is not clear to what to do. Have to wait for information from the manufacturer, ie. To the contrary is written in the AF. It is plainly stated. that focusing is performed through the mirror on the FAS sensors, and specifies the matrix due to CAF. Refine by FAS and absurd and impossible, t. To. FAF, as any system without feedback, always with an error.
