Plenty of detail, 13×19 inch prints at low ISO were very sharp, The Pentax W60’s images are perhaps usable to 16×20 for wall display. The limit for 8×10 inch prints is probably ISO 400, as our shots were quite usable at that size, albeit with a little noise in the shadows. ISO 800 shots looked surprisingly good at 8×10, but there was too much noise in the shadows for us to give them an official “usable” ranking. ISO 800 shots were good at at 5×7, albeit still with some noise in the shadows. ISO 1,600 was OK at 4×6, but with noisy shadows. (Better than most of its competitors at that ISO level, though.)
