New 85L - love it, but...

It looks like I am going to have to learn to use manual focusing in low light situations where the f/1.2 is needed. This lens is sharp! - It is the only one I have that equals the 35L. It is just won't nail the focus on auto focus in low light. Having said that, when you do nail it----------Wow!

My favorite prime.....I can't say that I've had any problem with it focusing in low light. Yes, it's a slow focuser, but it generally nails it for me.

Mark

Mark1 version tend to focus quite slow but Mark2 version is A.O.K for me

Yes, I think I wasn't giving it quite enough time under very low light conditions.
I don't find it any harder to attach than other lens - as some had mentioned.
This is one sweet lens!!

What camera body are you using it with... you have a bunch of them. Is it doing this also with the N?

Depending on the subject matter, I have trouble auto-focusing MY 85/1.2 in any light with an aperture between f2.0 and f1.2, but it tends to do better then any other lens I have period. The problem is the razor thin depth of field at those apertures.

this is why I usually take three shots wider then f2.8, one for me breathing at the wrong time, one for the model breathing at the wrong time and one for luck.

One of them 3 will be in focus.

Are you guys incapable of using MF? lol I know at that aperture it can be hard to nail it.... but, it's an option

Dont take that first sentence the wrong way.

I am using the MK IIN.

Jeff --------- your right, I've been lazy and gotten used to AF. The past several days I've been using manual focus and getting better. One of my problems is these no-line bifocals. I seem to have better luck taking the glasses off and using the diopler. The results are getting much better now and this lens is every bit the Q of the 35L or even better.

I purchased the 85L two weeks ago and I have been working with it on my 5D for a 3 days shoot that starts tomorrow.
I got word this morning that I will not be able to use a flash.
The minimum focus distance was the hardest for me, focus speed is OK because I am used to the 50-1.4.
Enjoy your new toy.
