5D Mark III Manual Available

[Alan Stankevitz]

Canon USA's website now has the 5D Mark III owner's manual available for download:

The autofocus section of the manual is interesting. Besides tracking sensitivity, there are now options for acceleration/deceleration and there are options for AI mode itself. Lots of reading to do.

one bummer with for the 800mm f/5.6 users, according to the manual 47 our of 61 AF points of the new system are usable with EF 800mm F/5.6 L. The outer focus points are disabled. There is no such limitation with 600mm (MKI or MKII) plus a 1.4X TC.

I think I can live with that as I always use the inner 9 points anyhow - am I missing something?

not missing anything not a deal breaker.

I wonder what the reason for this is- getting penalized for having Canon's longest lens. Reminds of the number of cross type points, and spot AF- where the 7D capabilities are beyond the Mark IV. Canon seems to be inconsistent in the abilities it provides with it's bodies and lenses. Wonder when Artie willl figure this out since he loves his 800mm. I'm also wondering if the 1Dx will have the same limitation.

Arash, I know you're wondering about 5D Mark III ISO capability compared to the Mark II. I think you currently have the Mark IV and Mark II. What do you think about ISO performance of these two currently? I've looked at imaging resource, and it seems that the Mark II is clearly better than the Mark IV by a couple stops, even acounting for the slight edge in resolution the Mark IV has.

I think the limitation for the 800 f/5.6 comes from light fall-off from the lens itself. It's not a FL issue since the 600+1.4 (840mm) does not have this limitation.

The 5D2/5D3 have similar high ISO performance to MK4 when shooting from fixed distance, in the case of 5D2 , 1D4 is actually better because it doesn't suffer from fixed pattern noise as much as the 5D2 does so noise reduction is easier. If you can get closer to your subject, of course the 5D's will have better SNR because of the larger sensor that collects more light but the difference is less than a stop. The JPEG samples on imagingresource.com can be quite deceiving as they have heavy noise reduction applied by the camera.
To evaluate the performance of each camera, it is best way is to download the RAW (CR2) files and look at the output with identical conversion settings. that's why they also provide the RAW files.
