1. Enjoy looking through a dSLR viewfinder that hasn't been chopped in half.
2. Be able to easily focus manual focus lenses by looking through a nice, big, bright viewfinder, instead of squinting through a puny APS-C viewfinder that has been chopped in half.
3. Take the same image on a dSLR with the same lens that I can take on film with my LX's, instead of having more than half of that image chopped off.
4. Use extreme wide angle lenses (rectilinear) that couldn't even be made for APS-C dSLRs, since they are built on a FF lens mount/registry distance, etc. (Got a 12-24mm APS-C equivalent "field of view" lens? A 14-24? Nope, nor will you)
5. When I take photos I'm extremely pleased with, be able to make extremely large prints with extremely high quality from them. The fact that I may not "need" to do this with every shot doesn't mean I don't
want the
ability to do so. I don't want to wish I had taken them with a camera with better IQ after the fact, since the pics I take are often not repeatable (I'm not taking pictures of fixed objects that I can re-shoot at will, as a rule).
6. Not feel like I have to take steps
backwards in order to move from film to digital, which is exactly what I'm doing if I have to "settle" for a smaller format.
Quite frankly, I see little "I NEED" sentiment from those desiring a FF Pentax, rather "I want it, because (fill in the blank)." It's the "APS-C is good enough for me and therefore it should be good enough for you" crowd on this forum that is telling those of us that want FF that we
don't "need" it. Sad that so many are so zealous about opining about why Pentax shouldn't produce what
others want, which would broaden the appeal of the brand (as opposed to shrinking it by turning those customers away); is it just the subsequent "buyers remorse" regarding your APS-C only lenses that you're afraid of?? I suspect so.
As for medium format, I have never been interested, not because image quality wouldn't be better, but because the available tools are extremely limited. The lens assortment available in 35mm format is tremendous, and provides so much more possibility. The size/weight/image quality balance of 35mm is just "right." APS-C digital is by contrast a compromise, since it is built around the 35mm size lens mount and register distance. As a result, there is no significant size/weight reduction to make a loss of image quality (not to mention the loss of more than half of your image, if you are using your 35mm lenses as are many) acceptable. Further, beyond simply cropping, if I want a "crop factor" with the same lens, I can just slap a teleconverter on it.
