Originally posted by rparmar People will still choose APS-C if it has advantages to offer. Right now those perceived advantages include size, cost and more telephoto reach. Not everyone sets aside a given sum of money and says "I'll spend all this on a body even if I can get a cheaper one." Otherwise no-one would bargain hunt.
Once FF dSLRs enter the price range of high end APS-C dSLRs, APS-C loses the only
actual advantage it ever had -
cost. The "perceived" advantages, as you put it so well, are just that - perceptions, and those are based on a very successful marketing campaign, not on ACTUAL advantages. One need only consider the answer to the following questions to bare the reality of the so-called "advantages" of APS-C:
Would you buy a 645D with a 24 x 36mm sensor in it?
If not, why not?
Essentially, that's exactly what you've done with APS-C dSLRs, is to buy into a camera made for a bigger format with a smaller format sensor in it. APS-C is and always was a compromise introduced for the sole reason that larger sensors were too difficult to make and too expensive to sell to most of the camera market
at the time. As the fabrication tachnology and techniques are advanced and the costs of FF sensors come down, that sole reason for the APS-
Compromise will be eliminated. You can rationalize the supposed advantages all you like (easy to do when you have no other choices), but the reality is that with APS-C dSLRs you have a camera and lenses that are much bigger and heavier than need be, due to the need to maintain backward compatibility with the larger 35mm format the cameras are based on (lens mount, register distance, etc. are dictated by 35mm, not APS-C, thereby making the cameras bigger and heavier), and absent the advantage of being cheap by comparison, not many would have ever "chosen" them. A price floor will be encountered based on the cost of the camera components
other than the sensors, which means that as the FF sensor costs come down, the prices will get closer together, and as that happens, suddenly FF cameras will expand their market penetration and a new marketing campaign will arrive to remind people what they've been missing.
There isn't any APS-C camera that Pentax will make (particularly in view of the assertion that Pentax doesn't plan to push the envelope on frame rates and the like) that will justify prices higher than the K7, so any "improvements" on what you have with the K7 are just things to put into K7 successors - a product above the K7 ("professional" grade, if you will, though I know that word raises a lot of needless arguments) NEEDS to be a full 35mm format. No intermediate steps (APS-H, or APS-ANYTHING), will do at this point - there has already been too much foot dragging.
It's been a long wait, Pentax - time for your FF dSLRs already!
