Actually, isn't IS a wee bit...well pointless maybe...on an 800? The amount of visible shake handholding that is going to be quite marked and you have to turn IS off when using a tripod anyway.
Honestly it's really quite useful on the long lenses. The 800mm I suspect will be used by the wildlife chaps, esp the birders and at f5.6, any additinal stop or two shutter speed you can get would be briliant. With the new IS (Nikon anyway) you can leave it switched on when on a tripod and so it is handy.Chris

Not on the newer versions you don't. It has a mode switch to turn off vertical IS for tripod and panning use.

Fair enough. I guess I'm jealous - my 400L doesn't have IS Chris

On the 800 f5.6 it's going to be a miniscule difference in the overall weight of the monster and your sherpa won't notice the difference so just go for it
