To drop cropped format - it wouldn't make any sense now, when Pentax is finally getting some attention after they introduced K-x and K-5. Probably they would build upon this to strenghten their position in APS-C format. With the selection of compact APS-C limiteds, small but advanced bodies I think Pentax have chance to become highly specialized APS-C producer if they build on strenghts of Kx and K5 and improve them in the next models. I doubt they will venture into FF region now...

so you dumped best Canon crop dSLR for beginner/enthusiatist Pentax model? Interesting.....
anyway welcome back...

Not really a Pentax, but I would love to get my hands on Zeiss 28/2 ZK and Zeiss 21/2.8...but should I choose from Pentax lineup F*300/4.5 or A*85/1.4 would be certainly my choices...

thanks god for great K20/4 which bravely struggles my desire for Zeiss 21. Hopefully K85/1.8 will not let me think much about A*85/1.4 too
