Originally posted by audiobomber The focus ring on my DA 40 wobbles, and the one on my DA*300, and my Sears A 135mm macro. I believe this is just cosmetic, the lenses are all sharp and no performance hit that I can see.
The barrel on my DA 16-45mm wobbled when it was new. I sent it for repair after a couple years of use, because the sharpness suddenly went off. I got it back, sharp as ever and no wobble.
It would seem based on the repair to your 16 to 45, that the lenses can be tightened up so they don't wobble. Lucky for me, I don't have any issues with focus ring being wobbly. That is nice and tight and smooth on all 3 of my better lenses; the DA 15 & 40 Limiteds and my DA*200. All take beautiful sharp pictures. Thanks for sharing your experiences with your lenses. I did buy my DA 40 used and I suspect it may have been dropped or bumped based on some minor paint scrapes on it. Still at about half the cost of a new one, I do feel I got a good deal. In the end, it is the quality of the pictures that matters most and there it really shines.
