I use center focus 100% of the time then recompose, and I love it.

i've been having an issue with one AF point in particular (bottom, right AF point) that has a lot of trouble looking on in perfect lighting conditions with any lens including the 135L which has one of the quickest AF out there. I need to send it in to Canon before the next wedding because it's a killer for when I'm trying to compose portrait shots and focus on the head and to the right of the frame. Other than that though, it hasn't been that bad. I will upgrade to the mkiii when it comes out if they give it anything close to the 7D AF because that and 1080p at 60 fps are my only complaints.

An interesting poll would be to see what percentage of users of bodies with more advanced AF systems (1D, 7D, any Nikon) limit themselves to one point. It always seemed rather silly to me that almost all Canon users with the 9 point AF systems turn 8 of them off. This really speaks volumes, doesn't it? I mean it's like buying a car and saying "I'm only going to drive on one tire because the rest are so crappy that I can no longer drive if I use all 4"

It will be interesting to see the final result of this poll. Currently it's showing that most owners are either happy or neutral and most non-owners are neutral. Let's hope that Canon's not paying too much attention when it comes to the 5Diii !

For me, the AF is adequate. The centre point is fine for most things. The outer points are not good in poor light. Servo mode is not as good as the 7D (or even the 40D) for fast moving stuff. However, the focus accuracy is good (or it is for me) when I use the centre point only.

I have no experience of the 1D, but I assume that is the bee's knees!

Coming from a nikon d300, this AF system is a joke. I never had the problems locking a subject on the nikon bodies as i do on the 5d2. My nikon d80 was better than the 5d2.

I'm an owner, and I'm perfectly happy with the AF.

Besides the D700, what other full-frame camera in the sub-$4k range has a markedly better AF system than the 5D2?

It's pretty obvious to me that Nikon went with the only full-frame capable AF system they had on the shelf to field the D700 and try to compete with Canon. Given that Nikon's latest full-frame sensor stuck to the 12MP level, I don't expect the D800 (or whatever it might be called) to match even the 5D2's resolution.


And truly, the only two things Nikon has over Canon are the D700's AF system and their SpeedLight system. Apart from that, Canon matches or beats them across the board.


And seriously, the AF system in the 5D2 is amazingly quick, even in low light. Having 42 more AF points would not suddenly increase the utility of the camera for me enough to justify an upgrade at this point.

I'm happy insofar as I bought the camera with my eyes wide open on the subject of AF and I have a 1D3 and 7D for occasions with more demanding AF needs. As it is I find the centre point to be excellent for action shooting, including BIF, and I have only been let down once by an outer AF point, when trying for an indoor candid shot against a very bright backlit sky.

The 5D2 is my "go to" camera unless I know that AF, frame rate or weatherproofing will let me down, or that I'll be so focal length limited that the 5D2 will offer no useful IQ advantage. More often than not it's that last point which makes me pick a different camera.

voted owner neutral. After owning a D700 for a year and a 7D for 6 months it's impossible to say I'm satisfied with it 100%, but it is good enough for what I need... barely.

Owner voting neutral. There're times I wished I could use (or trust) the outer points to compose, especially with fast primes.


6D + enough lenses for now.

I voted neutral. I'm not unhappy with it, but the peripheral AF points are limiting, as is the lack of flexibility. The 7D's system is much better.

I use it because its the fastest and most accurate, there is no guessing when i want to focus especially in low light. It just works for me very well. This way i have control of where i want the most focus (when using wide apertures)

I'm a 5D owner and a 5DII owner. I love the camera and the MkII is my goto body, but the one thing I do not like about the camera is the AF. It is adequate but no where near as fast and accurate at my 7D. It is the one weakness this body has. If it were not for the stellar IQ, I think this body would have been a bust. Canon needs to look to it's nearest competitor and wise up.

+1.

Why are we discussing rangefinders? Canon doesn't even make a rangefinder.

Ups... meant the S2... duh...

Edit:

I think so far the poll speaks for itself. - there is an overwhelming amount of positive responses, yes, some feel it's inadequate, but still - let's see where this goes.

I have used the 5D2 several times and find the AF adequate. It's definitely better than any Rebel and is on par to the xxD line IMO. I prefer the AF of my 7D and think it would be killer if Canon put that system in a 5D.

The 7D's AF is not rocket science either.

Bottom line... people satisfied with the 5D2 AF probably have not tried the 7D with its far superior AF system.

Owners who have both the 5D2 and 7D know without a doubt how the 7D AF system is far superior in every way to the 5D2 AF system. If they think otherwise, then they have no clue how to use the 7D to its fullest capability.
