Originally posted by Clavius My thoughts exactly. I don't think Pentax will ever market an FF camera. Which is OK, sensors get better and better. Try finding the differences between pictures from the 24mp APS-C sensor of the K-3 and those of a 24mp FF camera. There will be differences of course, but none that people will really care about. And they're probably in favour of the APS-C sensor too. That's why, countrary to popular belief, I'm guessing APS-C isn't the dead end street everybody claims to be after all.
There may be little difference between photos made by FF and halfsize cameras, it's true. But it's not the major difference between FF and APS-C: they are true wide angle, shallow depth of field and ISO high performance. Moreover, photography has developed certain standards during its evolution, the most popular and widespread being 24x36 mm (135) and the least - 24x16 (APS), from which cropped frame digitals evolved - originally due to impossibility to make FF sensor, then for its excessive cost. But if technology really is progressing as fast as OEMs claim, FF sensors by now should be cheaper than a carton of Marlboro, allowing to use with modern digital body all old FF lenses at their native FOV - that I want to do. I won't buy a set of special lenses for every new camera because it's silly - who knows how they perform? And old ones are well tested and known.
