50 1.2 Focus Ring Sticky?

[bob jr.]

Last night I noticed that, when i tried to focus manually at a great distance

with my Canon 50 1.2, the image looked blurry. So I looked t the focus ring

chart on the lens, and I noticed that the mark which represents infinity didn't

go all the way to the reference mark. So when I took a "running start" and spun

the ring kind of fast, it went all the way to where it should be. Does this

mean that my lens just needs to to serviced or does it mean that I need a new copy?

Was the image blurry- after you took the picture, or after you continually tried to focus until the image would get in focus. Never heard of any complaints with this lens, other than it takes a chunk of cash out of your wallet upon initial purchase. The focusing ring-in manual focus, should rotate smoothly and the image should quickly focus.

In case any one ever looks at this post again, i found the problem. It was the retaining ring just "upstream" of the manual focus ring (on the end-of the-lens side of the focus ring). It had become dislodged and was crooked. All I did was to put some pressure on it, pushing it in in the direction of the camera body, and it snapped into place. Problem fixed. i don't know what caused the ring to become dislodged.
