This is well known but when I see Canon's future offer of 20mp or 16.4mp etc (mind you, these are for the pro offering) I shiver :-). I do not have a 10mp camera but I am comfortable with 6mp and 8mp is just for having a bit of margin when it's required, plus 8mp sensors are off the shelf standard item. Other than that, I just took the 8mp figure off the air. If I do commercial photography, I might have to choose at least 10mp body by necessity, but glad I'm not. I just wish to enjoy taking photos and print them. Once in a while, I have to go up to A4 size but 6mp will do and 8mp will just enhance the confidence. I know that between 6mp and 10mp, one can see the difference particularly in the larger size print. But this is where you begin to see other potential problems (other than the lens issue) such as the sensitivity to the camera shake etc. Perhaps SR will take care of it, and it might actually be a necessity. In my genre of photography, I do not see any need of FF size sensor. Besides, the current DA lenses have larger image circle to take care of the sensor movement for SR, thus 40mm for example is usable in 35mm film cameras. But I do not know how much larger image circles the FF lenses might need in relation to the SR. Pentax have obviously been revamping the whole lens line in the last 3 years or so, and the next lens line will be longer telephotos DFAs with USM. I am curious to see what the image circle size for these lenses would be. But evry maker has been saying that the FF (or larger sensor) is almost strictly a matter of cost, and when everybody else offers so called FF size sensor, I do not see any reason why Pentax won't. But I wish every maker retains the APS size sensor anyway. So, to me, the FF issue at the present is a moot point. DA lenses are mostly to take care of wider ends of APS size sensor, which they pretty much completed, and any future lenses would be DFA. I do not think Pentax would offer something like 200/2.8 in APS image circle. No reason for it.
