85L autofocusing speed on a 5DII vs 5DIII

Anyone else notice the major difference between the two when it comes the autofocusing on the 5DII vs 5DIII with the 85L?

I was inches away from grabbing my car keys and driving over to my local camera store to sell my 85L until I started playing with it on the 5DIII. HOLY COW. Major difference. What's up with that?!

For all I know, I was about to switch completely over to Leica (M240 and summicron 35), but now having major second thoughts.

Is it just me or do you guys have the same feeling?

The focus motor is in the lens, so it cant be that much quicker.

maybe its more accurate. even the nifty fifty suddently transformed itself AF-wise from a 400d to a 5d3

And it is known that 85L has quite slow AF. Reason is that there is so much moving mass, because no internal focusing.
Makes me wonder how can it be so much faster with 5D3, compared to 5D2?

EF 85 1.8 USM focuses much faster anyway.

I actually witnessed a snail move faster then the 85L focusing.

I'm not sure of the specifics but the body does play a part in focusing. The 1DX for example has an entire separate processor dedicated to AF.

I appreciate that much of the body-side processing is to do with things like tracking in Servo AF modes, predicting where it will be and focusing ahead etc but I think the better bodies still focus faster and more accurately with basic one-shot too, but don't quote me.

I think to 85 gets a bum rap when it comes to focus speed. Sure, end-to-end, it is leisurely. Very leisurely. But that's rarely the scenario in active shooting.

Usually, in use, you're in a focus zone - maybe a variation of 3 ~ 8 feet at practical shooting distances - which makes focus acquisition useably fast.

But that was with the original 5D; I have no experience with subsequent models.

I use the 85LII with the 5d3 and it really opened this lens up for me to use for more general purpose photography.

The biggest win in my opinion is being able to use the outer points to focus accurately. When shooting at 85mm/f1.2 you just cannot center focus and recompose.

So whilst it's not fast end-to-end, once you've figured out it's quirks and realised that the focus is DEAD ACCURATE due to the super wide travel, it's really a pleasure to use.

I have always found the 85L II moves faster on any 1D body than on anything else. I always assumed it was the higher voltage that the 1D bodies operate at.

I don't think the 85L II is especially fast on my 5D3. For sure it is a lot slower on the 5D3 than it is on the 1D4. I can track sports with the lens on the 1D4, but with the 5D3 most fast moving action yields nothing but 'just off a hair' misses.

I agree. When I switched from 5D's to 1D bodies my 85 became much faster. I think its due to more current in the battery versus more voltage. I think the voltage is the same with all Canon DSLR's since they have to power the lens motors. The more current simply give the lens more "pushing power".

The pushing power has always been a function of voltage though. I owned the 1D2n for 3 years and always thought the 1D series runs a higher voltage battery than the rest?

Faster AF CPU in camera body makes AF faster, not the battery voltage itself.
1D series has always been in top of AF speed, they have powerful AF cpu's.

Never have issues with my 85L AF speed. Yes, not lightning fast but perfectly fine. This argument has been here for over a decade. I use a 1D, 1Ds2, 5D, and 5D2. All perform about the same......

I just upgraded from the 5dmk2 to the 5dmk3 my 85L focus speed feels the same, but on my friend's 1dx, it focuses noticeably quicker
