That was then, this is now. This Sigma 500mm lens is SHARP. I bought it because of Pentax in body stabilization. I am trying to decide if I should just sell all my Pentax and Sigma gear or hold on until the next Pentax body is announced? I have the Sigma 500mm Prime and the Sigma 300 mm prime. Both small and just a joy to use. Both would have a place in my bag if Pentax would get a good product out to use them with. It would be a perfect travel rig to say the least. Canon is huge!!! When going threw the airport I have to always sweat the check in with Canon gear.
This next pic is with the Sigma 500mm prime. ISO 1600,F5, 1/1600. Wasn't thinking and set the ISO to high. Been a long time since I used this gear. Still very sharp with pretty heavy handed noise reduction I think.

Just a lot of fun playing with this stuff. I have learned allot in the last two years since I changed to Canon.
ISO 500, F 4.5, Pentax K-5
Sigma 500mm F5.6, ISO 1600
If Ricoh will come to the plate I will try for sure.
Go birding, even if in the rain. I drove around today in the rain and had a blast.
