RE: PMA News: Pentax ist, new Lenses and Optio 450 and 550

Interesting - the film chamber is on the right!?!?

It seems to have the same type of on/off switch as MZ-S (perhaps DOF
too?), no self timer but a remote control option, a top wheel which has
no markings (presumably for shutter and/or aperture) and some sort of
button just in front of it (to shift between aperture and shutter
adjustment on the wheel in manual mode?)
