Originally posted by Zygonyx Well, you might find the answer if you use old but shining and fullcompatible Pentax or other manufacturers K-mount primes, but such an use is definitely not widespread amongst what i called " gogo "
I was actually being satirical in my first reply.
Shake reduction is one of the things that brought me to, and keeps me with, Pentax. If Canon and Nikon started offering in-camera SR, then I might give them consideration for my next DSLR (if they could exceed the value proposition of the competing Pentax model, which I find doubtful based on history).
Catch-in-Focus is another one of the great features that Pentax offers, but is hard to find on competing models. Although with focus-peaking, perhaps CIF is not as important for manual lenses as it used to be.
