I am seeking opinion from the experts here. I am a beginner here, with limited budget, but like photography alot. Used to have a compact camera, but would like to upgrade to a semi pro camera. Saw this camera that i saw, Olympus SP-560UZ, which is kinda within my budget. But realised that it's on 4xAA batteries instead of litium batteries. Any comment on this camera, especially on the batteries? Are AA batteries as good as Litium batteries? Thanks.
