Canon EOS Rebel t4i/650d specs revealed

[Flozem]

I love my 600D - I use both my HFS10 and the 600D, but the 600D imho is so much better in low light situations. By now I am really getting the hang of manual focus. I've also learned to not be afraid of using iso 800 / 1600- all to get that better exposure and be able to narrow the aperture. Downconversion to SD kills most of the noise anyway - my nicest shots had videonoise in there.

Anyway: Just make sure you pick the right tool for the job. If you have time to choose your frame, set exposure and focus- take the DSLR. If you have a videocamera backing you up: take a DSLR. For all else: a videocamera. But so far I've found the DSLR makes for the prettiest shots and best low light performance.

I will definately upgrade if the reviews are good on image quality / moiré and autofocus. A bonus if the recording time has also been increased. I already have a nice lens the 600D batterygrip, four batteries and lots of Sandisk SDHC cards anyway. Though I'm also thinking of upgrading the HFS10 to a HFG10, which incidentally fits the HFS10 batteries and accessoiries I have. Prolly will wait for a price drop though.

Yeah if you only output to SD/DVD, then ISO 1600 would be okay I guess. However, I already don't like the noise level on ISO800 in HD quality

Those functions aren't bad:
#1: Video Clip Length Up to 8GB or 22 Min
#2: Audio Recording With Video, Stereo

#3: the hybrid auto-focus during video.
#4: STM lens

I'm pretty much sold. I've wanted to replace my HV20 for a long time now but didn't know what to get. I've gotten use to using my 5DMKII or 7D for vacation video but nobody else in the family understood taking video with a DSLR. Since the T4i UI has commonalities with smartphone UIs then I think I finally have a something that the whole family can use.

I'm interested to see how good the autofocus is. Can it do a follow focus? If so that would be really handy for lowlight shooting even if you have to do a couple of takes to get it right.

[Janke]

Can it do a follow focus?

As I see it, it can do proper follow focus during recording only with the two new lenses...

[redfalcon]

I've read that the new sensor design still has aliasing and moire, unlike the 5D III.



Deal breaker.

Well if they don't cost a fortune that would be worth it. Doing a shallow DoF follow focus is not easy, but it does ad a nice touch to some shots. It would not be a problem to break out one of these lenses (if at least one of them is fast) for a shot like that.

[Janke]

IIRC, one is the "kit" zoom, the other a 40mm 2.8, so none yet really good for shallow DOF shooting...

With a T2i and Magic Lantern installed, you can do that, with an autofocus lens, like the 18-55mm. I tried it once.
You can use the trap focus to achieve that A & B, quick & easy (shown at around 2:10):

I just returned from Canon Finland's little get-together, where I could handle and try out the new T4i/650D. I shot a few scenes to check the new features. (On their card, so, no video upload, unfortunately...)

Sorry to say, the new video autofocus feature (with the new lens) didn't quite live up to my expectations. For a "family-videoshooter" it certainly is an improvement, but I felt it was too sluggish.

Pointing the camera from one subject to another, there was a pause of about one second, and then the focus "snapped" into place. So, for run-and-gun shooting, a dedicated video camera is still the best option.

If, on the other hand, you have the time to set up the shot, and have the camera on a tripod, then the touch-screen focusing is really nifty - just touch the point you want the camera to focus on, and (after that little delay), it does! (Don't know if it works during shooting, didn't think of checking that...)

The difference between the T4i/650D and the T2i/550D is huge - but not that big compared to the T3i/600.

[Eugenia Loli-Queru]

Did you also check moire/aliasing?

[Janke]

No, there were no corduroy jackets in the crowd...

[Dr. Benway]

In Finland? I don't believe it! Oh well, we'll have to wait for the Yorkshire round.

[Janke]

In Finland? I don't believe it!

Most of the people wore football team shirts - yes, Canon's get-together was Euro football cup themed! They had put up a huge tent, and projected the evening's two matches on a 10-ft screen... football is not my stuff - I came for the 650D ... but I really liked the pyttipanna* they served.

*Wikipedia knows...

[BarteS]

Odd you call it pyttipanna, not pyttipannu.

[Bertzie]

Some test videos are starting to pop up on Youtube.

Not odd at all, I'm a Finland-Swede... see: http://en.wikipedia.org/wiki/Finland-Swedes

What he is demonstrating there is "rack focus" going from a far object to a near one or going the other way. "Follow focus" is where the lens focuses on a subject and follows it as it moves around and changes distance.

I just returned from Canon Finland's little get-together, where I could handle and try out the new T4i/650D. I shot a few scenes to check the new features. (On their card, so, no video upload, unfortunately...)

As I suspected, Canon has managed to "catch up" to where Panasonic has been with the GH2. "Continuous autofocus" with that function designed into certain lenses seems to function somewhat as you describe. It does a lot better in good light like outdoor daylight, but in lower light levels it can "falter" some as it encounters lighting situatuations that cause most autofocus to begin to "hunt" or fail to "lock" focus well.

I'm glad to see Canon implementing everything they can and that function can be useful once one knows what the "lag" is likely to be.

Pointing the camera from one subject to another, there was a pause of about one second, and then the focus "snapped" into place. So, for run-and-gun shooting, a dedicated video camera is still the best option.

This can work very well for some who, working alone, may have to get out in front of the camera to narrate something.

If, on the other hand, you have the time to set up the shot, and have the camera on a tripod, then the touch-screen focusing is really nifty - just touch the point you want the camera to focus on, and (after that little delay), it does! (Don't know if it works during shooting, didn't think of checking that...)

I'm sure it does, and once used to that delay you can even effectively do a "rack" focus that way. I've been playing with that on the GH2.

I've made a switch to Panasonic GH2s primarily for the smaller size and weight of both camera and lenses. A "pound" of lenses goes a way lot further in the Micro 4/3 system and packs into a significantly smaller bag.

But I'm glad to see Canon implement what they have in the T4i. I could be tempted when I see what the high ISO performance is like (will it match the "clean" 6400 and usable 12,800 seen with the Olympus OMD E-M5?).

I still have some EF f1.8 primes on hand.

I'm not sure if you were thinking of using your EF primes in a "rack" focus the way you describe, but I thought that the auto-focus feature only worked with the new STM lenses?

[Eugenia Loli-Queru]

At least speaking for myself, this camera is useless to me. The video test shows moire/aliasing. You see, I already have a 5D MkII, so I would have gone for the T4i if it had the added value of no moire. But since it has moire/aliasing, it's not a good purchase for my case.

It would have been a good deal only if I had no dSLR at all.

If they got rid of the moire, they'd be shooting themselves in the foot over the 5dmk3. To introduce an entry level priced camera that has the video quality of a $3500 camera would be financial suicide.

I had the high ISO modes in mind when I made that statement, however if they've implemented touch screen focus the same as Panasonic in the GH2 where "touch" focus works with ANY of the Micro 4/3 lenses that autofocus, the "rack" focus would work with the EF lenses I have. That is a "qualified" IF.

It's kind of a moot point anyway. Like Eugenia says if they haven't solved the moire/aliasing issue and since the "noise" levels haven't really changed, I'll stay with the GH2's for now.
