Hello everybody! New at this forum.

I have a Sigma Mini Wide II (Pentax mount with A setting). It has a slight bit of a "wobble" in the focus ring. It is smooth when you turn it but you can wiggle it back and forth a bit (towards and away from the camera house if you understand what I mean). I guess there is something that needs tightening in there.

Does anyone have any experience how to take this one a part and do you know what I need to tighten to fix this?

Just googled and found some infos on the bottom first link. I think someone here may serviced this lens too.

Hello LIJ. I have this very lens and have disassembled it in the past, for removing the "Ricoh pin" and cleaning some elements, I think. I don't remember the details, but I would begin by unscrewing the beauty frontal ring. You will need some friction tool for this. I suppose you will find some screws below the ring and hopefully the means to thigh the focus ring. The filter rim in mine is badly dented, so I cannot remove it any longer Sad . If you have no previous experience, I would leave it alone, or take it to a repair shop. Regards

Javier
