Originally posted by pingflood Well, there is more to the story. Once you start reaching limits determined by diffraction, you won't be able to take any advantage of the extra resolution. Would you pay a premium for a 30 mpix camera that can only theoretically reach full resolution at f/2 or faster? Where are you going to get a lens that's sharp enough near or at wide open?
Technology might change that, although to be honest, digital sensors have not changed much since they were introduced in dSLRs...
I know I'm half-crazy and tjhat my English is not perfect but let me ask one question.

Concerning an hypothetical pentax fullframe, could it be possible that it would
be designed to use the same optics as the 645D... I mean specificaly the same optics
of the 645D. Some kind of Pentax secret plan in order to be in the capacity of pushing "the limits" debated above (... a sensor with film alike resolutions and the lenses to go with it).
See what I mean ? A 24x36 sensor with the lenses of a cropped 645. It could be the same scheme as aps-c with full frame lenses ? No ? And then they would have a good amount of time before the sensor reaches the limits of the lenses (if it can)...
I'm asking this question because it's said there wil be a Pentax fullframe in 2 years but still we can see no lens superior to aps-c size (no DFA's... exept the anachronistic 50 & 100 macro and the 55mm of the 645D ) and we know that they need to have an acceptable number of lenses before the camera is deliverd... even thoug the example of the leica S2 shows that it is possible to deliver the lenses and the at the same time, it's probably not the good thing to do for pentax. No ?
1. A big reason why people use Pentax is b/c the lenses are cheaper. These lenses are only cheap b/c they are optimized for APS-C sensored cameras. Why would you pay a premium on FF lenses on APS-C cameras ? The same applies to 645D lenses on FF.
2. The mount is not the same to my understanding, so a converter would be needed for any FF Pentax.
3. It would be much more cost efficient to simply remake the FA series lenses rather than letting pentax users use 645D lenses for their FF cameras.
4. Any CaNikon FF user switching over probably prefers zooms. The 645D system consists of mostly primes (good ones at that).
