I had both S100 and S95, in bright<a href="http://stmmmxzqqwj.com"> dlygiaht</a>, you can't tell which camera produce better picture. But indoor and low light big different between them. S95 can't use iso above 400 without notice lots of noise, with S100 u? can use till ISO 1600 still very usable. I compare them in low light. Is shocking the S100 indoor and low light image is as good as M4/3 with their kit lens.
