50 Art "squeaky" AF sound

YET ANOTHER 50 art AF issue thread, I'm so sorry guys...

The first 50 Art I had that didn't work had a slight squeaky sound, like high pitch "peeeep", when I ran the af back and forth between mfd and infinity.

The one I have now that worked up until recently, didn't have the squeak, and I had totally forgotten about my first having that sound, but today I heard it also in the new one and it has been on and off working for a while.

QUESTION:

Does your working 50 Art have a squeak?

Does your 50 Art with AF issues squeak?

I'm suspecting a defective AF motor on mine.

Thanks and Merry Christmas! 8)
 
I have mine 50 Art since april 7th this year. No AF issues and no squeaking sound.


Viggo, I am so sorry to hear about your problems with the Sigma lens. It looks like you and Sigma have bad chemistry. I seems a good idea to step away from Sigma. Maybe you have more luck some years from now.

Thanks for the info :)

Yeah, if canon had anything remotely close the 50 Art I would never have bought it. But 50 is my most used focal and the one I enjoy the most, but it has to be 1.4 or something like that. I loved the Zeiss mp f2.0, but MF is not an option. And since the 35 L II NEVER comes, I'm out of options...

No squeaks. Quiet shusshing sound. Accurate AF (after considerable tweeking).

Thanks! I found the dock to be "the devil", I zeroed mine out and did a +7 in camera and it worked a lot better, but it was quite a bit behind on infinity, so I though, easy fix! But as soon as I did a little front adjustment, it went to pieces with all other distances, and for some reason, became a lot more unstable. Tuned it back to zero and it started squeaking worse, so I don't know what happens, but it doesn't like the docking. Then again, it worked via docking on different values, but drifted and now it's no where near those values... I don't know.. Fingers crossed for Canon to release a 50 or the 35 L II... Handing it in for repair on saturday.

Hopefully my lens will keep working...Right now I love it....except I can't use it! Dropped my 5D III Body off at Canon today regarding the other problem we talked about that I posted with the focus points in my VF not lining up with my sensor. Had to pay them in advance??? Weird. $234. Get to pick it up some time next week...so that is cool. They do a whole cleaning and check over. The camera is almost 3 years old...so it is not a bad thing to do.. in general.
I have a complete Olympus MFT Kit...(just got two new lenses for it from Tokyo!!!! :P)...so I won't miss my 5DIII for a week.
Good luck with your lens!!!!!! I will report on the other page about how my repair goes on my Canon body.
I am interested to see how you repair goes with Sigma for your 50mm Art. I own one and after all I have read, and all the dancing I did to make mine work well....I always feel tentative about the lens....so it will be good to find out how Sigma treats you.
...but..boy..when that lens works...it is a BEAUTIFUL thing!!!!

Thanks for the info and feedback guys, much appreciated. That means mine is fixable. Handing it in a couple of hours, probably gone until mid January, but if I can't use as is, I can easily wait if it works out 8)
