Canon 7d mk 2 focus guide from Canon EU

Yesterday I had absolutely no plans to upgrade my current 7D... After reading the PDF about the MkII focusing capabilities, I'm having second thoughts

It was only the first volume about the AF system ... wait the next 15 volumes to read

On the 5D3 some time it's too much, like i change 1 setting, i'm not happy, i want to put back how it was ... but i cannot find back where was the setting in all those options and menu pages and loose 10mn to find it back

look at page 44 on the page numbers...


AFON and the * button can be programmed for independent case numbers and registred AF options. instant focus for one and ignore for the other!!!!

heck ya

This is really cool. However, it also looks like you can set the AF-on and * buttons to switch from one shot to servo.

EF 85 1.2 Mark I (the older one) is not on the chart that shows what AF points work.

would the Mark I have the same AF point selection like mark II?

Nor is the 400 2.8 IS or the 300 2.8 IS.

I would assume they would though. It's just the reallly old lenses that don't.

I wonder how the 3rd party lenses will act. Would the Sigma 18-35/1.8 act as a group A lens given the aperture compared to the other group A lenses. Also how would the Tammy/Siggy 150-600's act? Being a 6.3 fooled to 5.6, would it be I'm assume a group D,E, F or G. Hopefully its not G. At that point, the 400/5.6 with 1.4 TC is probably going to be as sharp if not sharper. It will be lighter too. As long as you dont need stabilization, and for what I would personally use it for, stabilization would be only minimally useful.

If guesing owners of the 5D3 would have an idea on this based on their experience with 3rd party lenses and I'm thinking it would be simular with the 7D2.

Great question. It will be interesting to see.

as third party lens I have only the sigma 85 f/1.4 (it's 2-3 years now)
no problems at all with 5D3, it work like a charm in all focus mode (and i can say that with this lens i'm often "stuck" at f/1.4)

I already called and asked and they consulted with one of the engineers who confirmed they will work the same as the II versions. They just listed the newest version in the chart; but as I pointed out they were not consistent as the older 500mm f/4 and 600 f/4 are listed in the chart when talking about the lens + TC.

I think I am going to get one of these and see how my tammy 70-200 behaves on it. My guess is that it will work quite well. The more I read about the 7DII the more excited I get about it. I really want it for wildlife and eventually underwater where the composition options will blow away what I can do with the Rebel. Underwater crops are the shizzle.

You forgot the F4.0 capable sensors... 5D3/1Dx has 40 of them.

True. They are a bit more accurate in one direction, at the expense of not working with f/5.6 lenses.
I think Canon expects users of APS-C cameras to have lenses with f/5.6 apertures at a slightly higher degree than what users of the 1DX have.

Impressive. This body hitting the market at $1700 bucks has got to ding the 1D4 prices, right? Right?
