I can't say I'm particularly struck by the looks of the camera or any Pentax for that matter but I like what I read it's capable of. The range of focal lengths available and the ability to shoot quite close interests me ... this is where my RF645 falls down somewhat!
I thought briefly about a prism finder for the 500cm but I've heard it's far from ideal and makes the camera rather unwieldy.
le vrai rdu
described the sound of the Pentax's shutter as being similar to someone falling down stairs!
