Canon 50mm 1.4 AF problem?

[scottsdaleriots]

Scott, I think you are confusing the Sigma with the Zeiss, which is MF only. The Zeiss is more expensive and, from what I've read, the bohkeh might not be great, due to its 9-blade diaphragm (the Canon's 8-blade diaphragm is rounder).

Yeah maybe i am. I know that (at least) one of the 3rd party 50mm lenses is only MF. Until today I didnt know that sigma made a macro 50mm lens.


I forgot to mention it's not only AF that quits from the canon 50mm 1.4 lens it's also the MF. They both stop working and it becomes a dead lens.

I have the 50 1.4 and I've never had a problem with it. It's a great little lens. Is it the same build quality as my L glass, heck no, but dollar for dollar for IQ, it's a great lens.

^ How old is your lens and do you use it with a filter? Im afraid that if i buy this lens, it will break after a few months

Just how exactly are you using (abusing?) your lenses if you can be afraid of breaking one after a few months? =/

And its not even the plasticky nifty fifty?

Lenses are not exactly easy to break, not unless you go out of your way to abuse it, and while the AF may fail - its pretty much what could happen to any lens if you don't take care of it.

Also:

MF failing?

where are you getting this info?

Unfortunately he's right. If you have the problem like I described above, the MF will also fail. This lens is notorious for this problem. The focus ring can easily get bent and severely limits the range of the auto or manual focus. This is not an isolated issue and if you google "fix canon 50 1.4 focus problem" you will see many results of people having this problem. Like I mentioned if you're not scared to open your lens up and fix it, it isn't a deal breaker but if you are rough with this lens, you will likely have problems. Actually I was much rougher with my 50 1.8 and never had any problems but I'm taking extra care with the 1.4 now. If this lens takes a hit to the front, there is a chance that you'll have focus problems but still, a great lens and highly recommended from me for its cost/quality.
