While visiting Chicago a few weeks ago, I noticed a line going from the left side, down to the bottom, on the beach pictures I took. My assumption was that there was something on my lens. So I stopped, cleaned the lens, and resumed shooting. I took a test shot to see if I'd fixed it, but the line was still there. I quickly went back through the shots I had taken that day, and the day before with a different lens, and sure enough, the line is visible in every shot. (It's more apparent in lighter shots.) So I took the lens off and there it was, a crack from the side of the sensor to the bottom. My favorite local camera shop took a look and said that I could send it in to Olympus but it would probably cost $300-$400 to fix it. To say I'm very sad is an understatement. I love my EM-5 and I feel like I was just really getting to know it, lol. I'm curious if anyone here has experienced this, heard of this, or knows how this could happen? It hasn't been dropped or overly manhandled, but I have been traveling quite a bit between very humid locations and very dry. (Someone has suggested this can cause problems.) I'm curious if it's worth sending in to Olympus to have fixed, or if there's some weird, known issue that Oly would fix it for free. Regardless, I've been looking at upgrading to the EM-1 and just made an eBay offer for $600 on a silver body with 540 actuations. Fingers crossed the seller accepts my offer--his asking price was $699 which is the lowest I've seen in 2 weeks.
