I have been thinking this over. Always dangerous.
Without SR I am not sure I would buy the 10 mp camera. It would
depend on whether the increase in resolution offsets the
increase in noise -- for my shooting. Also, there would
undoubtedly be a camera with SR following on in two or three
years, and I would want it. I cannot buy a new DSLR every two or
three years. Without SR, I might skip this generation of the D.
With SR I would want it. (Having the funds to buy it is a
different matter.) Having SR would mean that it would be less
necessary to use higher ISOs, so the higher noise would become
less of an issue. Also, the fact that Pentax is not bringing out
fast primes would be less of an issue.
So I hope the rumor is true.
