The ZR850 viewfinder is an uninviting, dome-shaped plastic frame with no soft rubberized coating to comfort the eye. Its ridiculously short length accentuates the bulky protrusion of the Li-ion battery just below. If this isn’t a dodgy design already, just wait until you upgrade to a bigger battery and attempt to bring your eye closer to the viewfinder. I understand Canon’s minimalist design intentions, but I’ve got a fever, and the only prescription is more viewfinder. The dioptric adjustment is located directly under this malnourished viewfinder, and the battery release button sits to its right. Having the controls on the LCD panel gives the LCD-craving point-and-shooter a bit of an advantage over the seasoned intermediate who wishes to conserve battery power and make use of the viewfinder.
