Well... For a very long lens that's true - but then just buy a long lens with OS and turn off the sensor shift. Best of both worlds, all your other lenses can be smaller/lighter and still benefit from an extra stop or two of hand-held stability. I've never acquired a very long lens because I know in my heart that I'll never want to carry it around. I have, OTOH, appreciated the extra stabilisation on M lenses from the 80s! Really good point about heat, and one I didn't even consider because I don't care about video even slightly! I guess Pentax users are a small self-selecting market.
