Sigma 100-300mm F1:4.5-6.7 DL Autofocus Pentax mount

Oldseabee · 04-30-2017, 10:49 AM

Hi, I just picked up one of these for $16.00. Going to use it to fill the gap between my 28-90mm and my manual 600mm. I also have a A series 300mm that I use. I'm also keeping an eye out for a reasonably priced Pentax 55-300 DA. Hard to find. Jim

I have one of the Sigma 100-300mm like yours but I find it's not that sharp at 300mm.

Also there is a listing for the 55-300mm metal mount in the Marketplace at what I think is a reasonable price, might want to check it out. It's not my ad, I don't own one of those.

I had a manual focus version of that lens, definitely not sharp at 300mm and more than a little cumbersome to use. I sold it off earlier this year.
