hey everyone...well i've just started having a problem with my camera, when i turn it on, it starts off fine, however after i take a photo, the viewfinder remains black...however all the menu items are still there...when i turn it off/on it goes back to normal...i'm thinking that it might have something to do with the batteries, as they haven't been holding a charge very well...and when i do charge them, the shut-off doesn't happen anymore, so they get hot..i'm hoping this is it...just want to know if i need it fixed, cause i'm heading to costa rica in 2 weeks, and have been looking forward to getting some good photos...thanks for any info
