Adapter for a Sigma Lense to fit a K10D

mi2nc · 03-08-2008, 12:13 PM

Is there such an animal? I have a slightly used Sigma 75-300 Lens that I gave my wife and myself for our honeymoon to Alaska 13 years ago. I would love to use it on my K10d.

I believe early on, i.e. late 1980's sigma was a liscensee of the pentax K mount, but products diverged when AF started.

I think your lens might be too late. you would need to find a sigma site to find compatibility of old lenses with different bodies

I have the same lens at home.

If it fits the Sigma mount I might be willing to trade it straight across for mine that fits Pentax mount.
Although it would have to be in the same shape.

I have two 70 - 200 lenses, plus one 135 - 400 lens in Pentax mount already, so I can part with it.

Yeah this has AF so I think you are right. They won't mate properly.
