New cheap 500mm lens on SD15
Aug 9, 2012

I thought for $125 I would try one of the Samyang mirror lenses. I have read reviews the say these are horrible and other reviews that say they are OK.

I ordered the Optica version of the lens with the Pentax mount. It fits my K5 and Sigma cameras.
It's F6.3 at 500mm

Pentax K-5 Sigma SD15
