Hi, I am considering an upgrade from 5DII to 5DIII. I often have mis-focused shots with my 85L on current 5DII and it was too slow also.

I am wondering if anyone has experience using this lens on the two cameras and how much of an improvement is there?

Btw, this is an evil forum. A month ago I didn't think I would need a 5DIII, and after browsing this forum for a while, I am now all ready to pull the trigger on it....

Not sure why you have this problem.

I use my 5D2 with 85L II with central spot focus, which works well mostly; only @ f/1.2 for close range portraits shoots - live view.

As I only have my 5D3 just month or two, which is definitely better than my 5D2; but I still use live view for close range portrait to get the best result.

I use my 85L to shoot my baby boy who doesn't stay put very much when I shoot. In fact he is quite unpredictable. Also I shoot at f/1.2 so a slight off focus shows up very clearly. Live view is relevant for me since I am not taking photo of static object.

My usual setting is AI servo with the centre AF point on his eyes, but the tracking of the 5DII leaves a lot to be desired.

It's probably not the fault of your 5D2.

85L is not considered to be an "action" lens.

It's somewhat slow to focus (it's moving a very large chunk of glass) and the DOF @ f/1.2 is just razor thin. Just the slightest motion toward or away from the camera and you'll get an OOF shot.

85 f/1.8 is much quicker to react to motion as would be a 50mm f/1.4

The financial hit of moving to full frame might not be so bad in a few months

The 85mm L I and II will both be slow auto focusing on any camera body.

You need a 135L.

Don't have 85L but folks saying it perfoms much better on 5dmk3.

Every review I read states that the 1.2L lenses are a bit slower than the lower-tiered lenses. I gave the 85 1.8 a go with my 5D3 at a parade event and that thing was snapping to focus so fast it was incredible. I missed focus on one photo out of 150 and that was my fault.

I can't speak about an improvement because I never owned or shot a 5D Mk II (went from 7D to 5D Mk III). With that said I have had very few problems with my 85L. Only issues I've had but it would probably happen with any camera body and this lens is when it's very dark (and I mean dark/ISO 12,500+) I sometimes have to manually focus the lens. Also when I shoot at f1.2 I need to make sure that if I have two or more subjects they are all exactly the same distance from the lens. The DOF is so razor thin that if I'm 8'-10' away and one subject is "3-6" behind/in-front the other one will be out of focus. If I only have one subject it hasn't been a issue. Outside of this I have to say this body + 85L lens = killer combination. Like another poster said, I too only use use center AF point and place on one of the eyes. I typically only use ~f1.2 when the subject(s) are stationary to avoid Servo as I seem to get much better pics when the subject is stationary. You are going to love the 5D III. I don't miss my 7D at all!!!

Why only using center point AF with 5dmk3?
