Anyone have any experience with any of these cameras I'm looking to purchase one off of ebay - as alternative shooting at least once or twice a month - and I'm not sure which one to get. very light usage though. i've read on some of the listings that the light seals have been replaced for some cameras or either have been replace. Without looking it up, I don't know what it is, but have an idea. Is this something that is common with the om-1, om-2 and has been corrected with the om-4. obviously, it won't be my main camera but i'd like to do some film work and can use the lenses with my e620. any thoughts on what one model over the other? it's really just for play. also what about the olympus om10 - i found a used one for $35.00 and that could suffice. any experience with any of the om cameras you have would be appreciated. i think i saw a several reviews on this site and will go back and read them. i'm leaning toward the om4, but being that i won't be using it but a few times a month, the om1, less expensive, would be okay. just trying to figure out what's all missing from the om1 and om2 that the om4 has. thanks in advance.
