Originally posted by mikesbike I would have recommended the KP in a minute, except it seemed by the OP's comments it might not be possible due to budget concerns. If it is possible, THAT would be a huge upgrade!
We picked up a K-5IIs yesterday. Nice camera. The negatives are overstated. On the DxO sensor database the K-5iis is rated at 82 combined score. The K-3 is rated at 80. A KS-1 is rated at 78, a K-7 is rated at 61. Differences of 5 points are discernible to the naked eye. They haven't yet rated a K-P or a K-70.
At $200 U.S. I feel like we stole the camera. It came with the grip and 2 batteries.
We also use the DA 55-300 PLM on our K-5. As a telephoto, we use it without issue for pseudo-macro and wildlife and even some birding on both the K-1 and K-5. It's limitations are overstated by those unfamiliar with using the equipment.
