        hi, how do see/compare the low iso performance of the two cameras?

        Come on Snapsort, you need to sort out your scoring system.

        The A580 is a very good camera, but the A77 is unquestionably better in so many ways. You award the same score to both cameras for video, without taking into account that the A77 has a superb ultra fast video focus, whereas the A580 doesn't video focus at all. I used to own an A580 and found the video useless for anything that moves! Also you score electronic viewfinders zero (the same as no viewfinder at all) why?! Okay score pentaprism highest then pentamirror, then electronic, but a score of zero (i.e. of no consequence whatever) is just silly when the A77 viewfinder has been widely acclaimed.

        Edit: Scoring now appears to be revised, so A77 comes out ahead of A580, but A77 still scores zero for (its excellent) electronic viewfinder
