My EF50 F/1.4 AF died last night

[Moody Blues]

So I am shooting kids las night. Everything with the 50 1.4 is fine. I get the camera back out after they go to bed and notice that the AF is not working. I check to make sure the selector is on AF. I try the lens on 2 other bodies with the same result, no AF. The lens meters fine, just no AF. I tried all my other lenses on all the bodies and they all work fine.

It's seems funny that it just died, the lens is only 7 months old.

Just to avoid the obvious, did you check the AF/MF switch? ;)

".... I check to make sure the selector is on AF..." probably means he did..

Ouch, broken fifty, I'd sink into deep mental depression immediately :(

Um, yeah, I stated that above.

Not to worry, should be under warranty.

try switching it between M and AV just make sure the switch is OK - otherwise back to shop for replacement

I tried all modes. I noticed, when shooting the kids, that it seemed like it was having a hard time keeping up in Servo mode. I just wrote it off to lighting and the fact that I have been so used to my L lenses, but I guess it was just slowly fading.

Oh well, I guess it's off to Canon on Monday. I am also in debate on whether I am going to send my 70-200L 2.8 back to Canon for a piece of debris near the rear elements. I did extensive tests with both cropped and full frame bases and it seems the debris is well out of the line of view.

Moral of that story is that I hate sending something off to get taken apart when you can live with it the way it is. Obviously the 50 needs to get fixed. You just hate to send something off for something like a piece of dust, that has no effect on the shots and get it back with others problems from being dis-assembled.

The exposure mode on the camera would have no bearing on the lens.

Try switching the lens's autofocus mode from M to AF and back and forth, just to make sure the switch is OK.
