The A10 doesn't leave any room for an optical viewfinder, so you're stuck with the 2.5 inch LCD. No worries, since the 232K pixels of the screen provide a sharp, color accurate display. It's not completely fluid while panning the camera moderately fast, but it is adequate. The LCD was a little hard to see in full sunlight. Even with no optical viewfinder, you can toggle the display completely off using the Ok button. Continued presses of the Ok button present varying amounts of information, with the most informative display showing the mode, flash status, Shake Reduction status, battery status, image resolution and quality, white balance setting, metering mode, ISO setting, and a live histogram..
