Pentax Optio 750Z Review
Top of camera controls
Top of the 750Z is dominated by the mode dial which surrounds the shutter release button (good half-press feel, click full-press). Surrounding the mode dial is the 'front lever' which doesn't as you may think adjust the camera zoom but is instead used to change settings such as exposure compensation (quite a confusing bit of design if you're used to a top mounted zoom lever). As I've commented in other reviews I would have liked the on/off button to require a one or two second 'hold' before powering the camera off, this would avoid accidental power offs.
