Originally posted by sjwaldron It might be a good idea to find a local camera shop or friend who has a K-7/K-5 that you can hold. I have a K10D and K-7 and think the K-7 overall is more solid/compact and around 50 grams lighter (0.1 LB...eg not really that noticeable weight wise).
+1. There is nothing better than to try hands-on a camera. Try to get to a store that has the K-7, K-5, K-x and K-r to compare the body.
Alternately, try to see if there is any Pentaxians in your area and organise a meeting face to face to compare cameras. I believe that there are a number of Pentax forums members from Oregon, and you could post a message to them?!
The K-7 is an excellent camera, but the body is slightly larger than the K-x. I have relatively small hands and I felt that the K-x was slightly too small for my hands. The k-7 was perfect fit. If you have small hands, the K-x and K-r might be a better try.
However, do not forget to try the camera with your lens(es). My main lens is the DA18-250mm, that is heavier than the kit lens. With the 18-250mm, I felt that the K-x was not as well balanced as the K-7. Again it is a personal/subjective feel but this your camera, your lens, your decision.
