Title: HELP! My sigma 17-50mm f2.8 lens LOOSE ELEMENT! Post by: michaelbyz23 on October 05, 2010, 06:23:47 PM Hello guys, I just recently puchased the 17-50mm f2.8 sigma lens. Mine appear to have the loose lens element.
I have recorded the situation, hope you guys can help me! i just received the unit today from 47th street camera. http://www.youtube.com/watch?v=bPTa6Xxi-nk This is the 18-55mm canon Kit lens, i use the 17-50mm to shoot this video. it seems that the lens is working fine. http://www.youtube.com/watch?v=OS-b70mUG0s Is this normal? Or should i return it to the seller? Title: Re: HELP! My sigma 17-50mm f2.8 lens LOOSE ELEMENT! Post by: Bob Atkins on October 05, 2010, 07:16:12 PM It's the IS mechanism. Mount it on the camera and turn the camera on and I'll bet the rattle goes away.

The review will appear here in a week or so, along with a review of the Canon EF-S 17-55/2.8 IS (which also rattles, but less then the Sigma!). Title: Re: HELP!

I also hope to see how the Canon rattles, compared to the Sigma. Thanks alot!
Now I am much more relieved. |
