I found an olympus stylus infinity. About to pick it up but i realized that the front panel that slides was partially chipped and it the battery was dead so i passed on it. then one day I walk in the thrift store and I find the exact same stlylus infinity but it had power this time (which i find really weird). It seems to be snappin' pictures ok but i was worried that maybe the aperture or the focus wasnt working correctly, so I passed. Should i have picked it up?
