Originally posted by Digitalis IF we left out the SR mechanism, I think it would be rather easy to come out with a DSLR with a svelte form factor like the LX - but I don't see that happening.
I'm not sure why would Pentax be married to a SR in all of their products? In a camera form like the RX-1, Sony has not introduced in body anti shake / shake reduction. Neither Fujifilm has it in their X100s and the X series. Leica doesn't have it either. Nor Nikon and Canon.
It is nice to have, but not absolutely necessary as the differentiation factor; all others prove it.
If Pentax really thinks the LX form factor would sell, one stop light advantage of FF over the APS-C already works as a form of shake reduction. Better that, than potential users shaking off Pentax as an irrelevant player who always comes late to the game.
