Originally posted by Serkevan Well, the D780 has lower resolution, lacks GPS and on-board flash, has no IBIS, no cross-tilt screen. It of course has better AF, more speed (7 vs 4.4 fps), what looks like a great metering sensor and a touchscreen. Whether those features make it worth 4 or 500 bucks more than the K-1 is a different story. But more importantly, it's a Nikon. If you have a bunch of Nikon glass, then the D780 is better than anything Pentax (or any other DSLR brand) can offer.
Sure, I should have said the Canon is not positioned as a lower class model and the Nikon might be something alike that in the Nikon universe, but still pricewise above any Pentax camera (not counting MF).
The K-1 is at 1499 € a great offer and as affordable as a entry FF- model could be. If you downsample the 36 Mp to 24 I'm sure no difference in DR or noise would be evident.
