What would you like to see improved on the 5d Mk3?

Pieces of information from canonrumors.com:
5D Mark III Specs ?
"Two different pieces of information put the camera above 30 MP. It will not have a pro AF system. It was suggested that the AF will be a version of the 7D autofocus system. The camera would have a frame rate of 3-4 fps like the current 5D Mark II. It will be equipped with the DIGIC 5+ processor and be aimed at high MP, high ISO performance. There were no details given about the video functionality of the camera."

Well i hope it has more than 1 cross type AF sensor. Thats the thing that makes me wonder why people use the 5Dmkii as a professional. Maybe its the top LCD?

For me, the resolution to make large prints. I started out with a medium format camera with a groundglass--a TLR--and I used view cameras and medium format SLRs up until a couple of years ago. the 5D2 Live View is as pleasant to use as a medium format ground glass...actually more pleasant. It's a much different way to see because you're looking at a "picture" instead of "peerin' through a tiny 'ole."

With the 5Dii they used rebel like autofocus but at the same time gave it a few professional features like the top LCD and lens micro adjust. The 5Dii could have been so much better if it had atleast the 60D AF system. Even they took away the other features to compensate the cost. I hope canon split the FF market into more categories like they have with the crops. If they release a rebel like FF at a good price, it will be a top seller. The 5Diii can have the better AF and the few extras like top lcd and micro adjust and the few extras.

The 5D and 5DII have neither a Rebel or xxD AF system. It is unique to the 5 series cameras. Whereas the xxxD and xxD cameras have a 9 point AF system, the 5D series have a 15 point AF system with 9 selectable points (like the xxxD and xxD) and 6 helper points around the center.

A lot of folks bash the 5D AF and granted it is not fast, but it sure as heck is accurate.

For more info, see the Canon white paper, page 31 and 32.

5D's dont use Rebel(-like) AF. Layout-wise, Canon took the 30D and added six assist points. AF algorithm is not the same, either. Read the white papers if you're so inclined, and quit making up BS.

Unless you're saying the 30D has Rebel-like AF.

Just two things. Greatly improved AF and greatly improved dynamic range.

In order of priority:

- Better shadow noise (especially with regards to pattern noise in shadows)
- Better dynamic range (at least equal to Nikon D3x and the other Sony sensors)
- 36+ megapixels
- Weather sealing
- 5-bracket HDR (or more)
- Better AF (at least give it functional outer AF points!)

They really need to make this one competitive with the Nikon D800 - if the rumoured 36MP is correct, and it also has the pro AF, great DR, weather sealing and good shadow noise characteristics common to the D700, Canon has a real fight on its hands.

IMO not putting in a good AF system in this body will be a death sentence for the 5D line - all new users (and those with multiple systems) would go for the Nikon, while the only reason to go for the Canon is if you had a collection of Canon lenses. And maybe for video...

I think canon are purposely waiting for nikon to go first this time so that they can see what theyre up against. Competition does appear to be very hot. I dont know if i want 36+ megapixels. If you shoot landscapes /still life / studio its fine, but for wedding photography i dont know?
I have a feeling that canon are going to split the FF market and we are going to see more choices. If the 5Diii is going to compete with Nikon then there will be no affordable FF cameras anymore. That leaves an open market for a lower spec FF rite? Or even so, dont be surprised if the 5Diii dissapoints in spec but gains in price advantage and then they introduce something else to take on Nikon.

Canon didn't wait on Nikon before they announced the 1DX...

probably because they thought it would blow away anything Nikon could offer. If it wasnt for the loss of f8 AF that could be true

There are no lenses with a max aperture of only f/8...

500/600L (among others) with 2x TC
800L (among others) with a 1.4x TC

Pretty useful for wildlife and sports...

'High ISO performance' doesn't make sense when paired with a toned-down 7D AF system. There's no point being able to take clean shots in the dark if the camera can't focus quickly and accurately in the dark too.

I said there are no lenses with a max aperture of only f/8.

I didn't say there aren't photographers who try to cobble more reach out of TCs and paint themselves into a corner with a max aperture of only f/8.

Show me a pro using a 2X at a major sporting event to get 1000mm or 1200mm @ f/8. I've never seen it.

As for wildlife, I've never seen a Deer or a Bear bust through the line of scrimmage so quickly that MF wasn't possible.
