I've using the k20D since they came out and really enjoy the camera a lot. I did pick up a K3 and am impressed so far, but haven't had a chance to take that out in the field. The K20D, now that a different story!
Proud member of the k20D club! I wouldn't call myself anything but a hobbyist photography...I took up photography years ago to document birds. Went from film to K20D. I try and improve my skills as I can. For me half the joy is in the opportunity to see wildlife, the other is to try and capture it so I never forget the feeling.
These were taken with my K20 D and old trustworthy SMC F 1:4.5 300 ED [IF] in the Everglades. This lens and camera have really worked well for me. Small enough to hike around with, big enough to do the job passibly (for me).
