Hi guys, im all new here. i just jumped ship from Canon (7D) and bought a K5
for its landscape capabilities. i am fairly serious with my photography,
both landscape and wildlife (mostly birds of prey) as i hope you will
see by looking at my website
i have had a fair bit of big L glass from canon, and im now looking to
find something similar in pentax mount. so for my wildlife needs i have
been looking at the Sigma 300mm f/2.8
anyone here have some experience with this lens. focus speed, color, etc ?
i know it's not HSM in Pentax mount, but what is it... screw-drive ?
Thanks in advance
