Full-frame Canon DSLR with continuous focus while recording video?

thegrindlab — Thu, 28 Jul 2016 13:01:41 GMT

I am looking for a full-frame Canon DSLR with continuous focus while recording video that equals or surpasses the quality of the 70D. Can anyone make suggestions?

Thank you for any help.

What is your budget? Why a full frame DSLR? Why not buy an actual video camera like a Canon EOS C100 Cinema EOS Camera with Dual Pixel CMOS AF?

I'll begin the discussion by repeating the sound advice we usually give in response to that question: Get an actual Canon video camera. Professional requirements deserve professional equipment.

[Edit] I see Waddizzle beat me to it. No collusion there; most of us just think alike on this matter.

My budget is about $2k. I am interested in any model that works with my current lenses (all EF mount). Thanks for the reply.

My advice hasn't changed. Consider an EOS Cinema camera, which are priced 50% over your stated budget. If video is your prime consideration, then you do not want a DSLR.

DSLRs typically have CMOS sensors, which are good for capturing very high resolution images over a short period of time, just like a photograph. They tend to quickly gather heat to the point of overheating and shutting down when used extensively for video.

Cinema cameras typically have CCD sensors, which are good for capturing accurate images shot over an extended period of time, just like a video. They DO NOT have very high resolution, but which is more than adequate for video, and do not suffer from heat buildup.

Thank you for the advice. Since I already have DSLRs, I'll look into upgrading to an actual video camera.

The Canon EOS C100 Cinema EOS Camera with Dual Pixel CMOS AF is currently on sale at clearance pricing.

I don't follow video, but, have you looked onto the changes made in the 80D over your 70D?

Even a crop sensor dSLR has a huge sensor compared to dedicated video cameras.

Apparently the 80D does NOT do line skipping like the 70D, which means it will have a significant improvement in video quality.

So, what. Did you know that many professional video cameras use more than one sensor, one for each primary color?

The model I cited has an ISO range from 320 to 80,000

I looked into it, but it's also uses a crop sensor.

Are you looking for a particular depth of field? That is the only reason to go FF sensor.

I would just rent all the Canon FF cameras and buy the one that meets your needs. We don't claim to be video experts here. In fact, the rental company might be able to provide better advice than us, especially if they specialize in lens rentals, hint, hint.

The Cinema EOS C300 has a sensor with 19 micrometer pixels.

Still looking for specification on the size of the pixels in the C100 cameras. It's a safe bet that they are quite large, too, much larger than those found in DSLRs. Anyone doing serious video doesn't want to use a DSLR, with perhaps the EOS-1D C being the lone exception from Canon..

It's the size of the pixels that make the difference.

Re: Full-frame Canon DSLR with continuous focus while recording video?

The 80D uses pixel binning combining multiple image sensor pixels into one.

This is different than the 70D which used line skipping, effectively reducing the image sensor area in half.

According to page 4 of this article

http://learn.usa.canon.com/app/pdfs/white_papers/White_Paper_35mmCMOS.pdf

,,, I believe the pixel pitch [for C100] is 6.4 micrometers, which compares to the EOS 6D at 6.55 micrometers.

Depth of field is one reason. Better results in low light (and higher ISO) is another reason. Lastly, with what we shoot, though we can always step closer for a tighter shot, we cannot always step away from the subject to get the (slightly) wider shots we want.

If you want a full frame sensor, and full time AF when shooting video, then you should be looking at the EOS-1D series, particularly the EOS-1D C, I suppose. The 6D isn't well suited for video, and lacks the full time AF. I do not believe the 5D3 has the full time AF, either. So, that leaves just the 1D series, if you want a full frame sensor and continuous AF.

Thanks again. That is very useful information I have not been able to find on my own.
