If I am going to end up with K5-level pixel densities on this thing in APS-C mode, I'll not be unhappy at all. I already have the K-5, so unlike current K-3 users I'm not going to miss a thing in APS-C mode and with any luck I'll score a no-AA filter with better processing algorithms and other goodies.
I can live with that.
More and more, though, I'm thinking we're not going to get a decrippled mount. They say "compatible with all lenses", but they keep mentioning the FA series half in the same breath. Until "compatible with all lenses" is better clarified, I think I'll resign myself to the current situation. Then I'll have the joy of being proved wrong instead of the crushing disappointment. Best of both worlds!!
