Canon EF 85mm f/1.2L II AF really that bad?

Over and over we've read that the AF on Canon's EF 85mm f/1.2L II USM is very slow.

I know this is a special lens to many shooters. I think I've also read that an f/1.4L replacement is in the works.

My question are whether the AF is really that slow? For portrait work?

This just might be one of those classic lenses that will have no match in the future, so I'm wondering what actual owners really think. Do you shoot at f/1.2 often? Would f/1.4 really be that much of a bokeh trade off if the new lens comes with IS and faster focus?

I have the 135 f/2L (my fastest lens), but the focal length is limited indoors.

The AF is good enough to shoot action with some experience. For regular portraits - it's more than fast. Wonderful lens. It's sharp at the center @ 1.2, and super sharp @ 2.8.

I had a copy of the 85 f/1.2 Series-I and you could only describe the AF as glacial! I didn't keep it long. The 85 f/1.2 II is a big upgrade in more than just the AF. The 85 f/1.2L II's improved focus mechanism is about 1.6x faster than the original lens - noticeably faster and a very nice improvement, but not as fast as Canon's fastest autofocusing lenses. While this lens certainly has the aperture and image quality to be an excellent indoor action sports lens, the AF performance is only "good enough" in my opinion - and not matching the Canon EF 85mm f/1.8 USM Lens' AF performance.

The AF can be slow, but on point. When you focus on subjects that are not too far away from each other, its not that bad. The 85 1.2 forces me to slow down before taking the shot.

To me, the combination of 1.2, color saturation, contrast, and sharpness makes my pictures stand out.

When I first got the 85 1.2, I found that when I used back button focusing at 1.2, my images were blurry. When I used my thumb, I jabbed the camera forward to create camera shake.

If you're shooting with a 1-series body then it's still on the slow side but not terrible. If you're shooting with anything else it is quite slow.

This is interesting. It is the first time I've heard of a 1 series speeding up the AF of something other then a big white. Good to know.

Noticeably faster on the 5DIV than the 5DIII. I've been surprised by how much better it's tracking with AI Servo. For a child strolling towards camera, not moving too erratically, works fine.

It is a lens for a special purpose--portrait photography. Considering that at f/1.2 and 4-5 away the DoF is about as thin as rice paper, the AF is exquisitely accurate.

By personal experience I can tell you that the 85LII focuses much faster on 1DX/1DXII, than on a 6D or 5Ds. It isn't fast on a 1DX, but it's fast enough for most practical use. As long as you don't have to focus from near to far, I would say it's hard to notice that the AF is a little slow.

The batteries on the 1D series are more powerful. That must be the main reason why AF is often faster on 1D bodies.

Thanks AJ. It doesn't look like much of a difference to me. Might just have to wait on the updated version that will probably have the BR coating too.
