I don't know how much to expect out of that kind of length on such a zoom, but super-megazoom bridge cameras are actually a lot of fun kind of *because* you're toting this really long lens around where you otherwise just wouldn't be pointing like a 400mm lens in the first place. It's photos that otherwise just plain wouldn't happen.
Just one thing: Hey, Pentax, would you put a blessed eyecup, or at least mounting slots, on these things, already?
Someone's gonna have to do it eventually.
One thing about these little guys that's of use, by the way, is to put a knob or handle in the tripod screw: what I found incredibly handy is an old Bogen/Manfrotto "mini-flex head." It's the only way I could really do a steady vertical at those kinds of ranges, or any) and is crazy-useful with either off-angle shots or otherwise using the LCD view, or chimping with one hand, or whatnot.
Here's a photo of my little guy:
For steady at long range, you can hook your left thumb under the rubber head, and curl your fingers over the lens and barrel like you might with a mini-camcorder, and do surprisingly-steady verticals. It's also a natural top for a monopod, (The idea behind these is that for a larger camera, they'd simply become bendy under pressure. That doesn't really fly with a little bridge camera. Not far, anyway. But they're still about the perfect shape if the tripod screw's in a good place and they're very pocketable.
