I bought the EM-5 back on the 23rd of July in 2012. I dropped the thing within the first week of having it (out of my thinktank bag while changing stuff), which was a total bummer, but only scuffed the bottom plate and the top corner, grip was ordered that day. Most of it you wouldn't be able to see because the grip has remained on ever since. I've used the camera extensively with the GX1 I'd only bought two months before primarily as a backup. I didn't do a shutter count before I sent it in, but I know I hit the 30k mark though as I was in the high twenties before I went to Hawaii and have run up another 5,000 or so frames since then. Last week I was working out in Boise, took some shots with the camera my first day of the future in-laws dog, etc. Second day I worked from 8-6 and got back in my car to head to their house. Saw some great light falling up on Bogus Basin and grabbed the camera out of my bag, swapped the 45mm to the 75mm and noticed a dark spot in the corner of the screen. Thought, "hey this is weird". Took the lens off and it was clean on both ends. Put the lens back on, still there... So at that point I look at the sensor and see a crack forming in the lower right hand corner. The camera had been in my car in a parking garage all day with the Olympus 45mm attached, and randomly this happened. Later that night the crack spread and split into two. By the next day it was completely across the length of the sensor. That day I went into the shop I got it from, talked with them about it, filled their form out, and then decided to call Olympus myself. Of course they transferred me to two different people, who couldn't tell me if they'd had similar issues as this. I brought up the fact that I had read on the board that another user had this same issue with his camera and that others I read about from searching (mainly in Europe) had also had this issue. To quickly summarize my understanding, the glass attached to the sensor wasn't adhered properly and caused stress over time resulting in it actual cracking. Of course my problem in the matter is that the camera had been dropped before, I made the argument with Olympus saying that I've used it for months and many thousands of frames with no issues since dropping it. Unfortunately I can't really prove that and frankly after finding out the replacement cost was $163.xx, I just want my camera back. I paid the expedited shipping and let them know that I'm using this for a paid assignment in a couple weeks, so I would appreciate their effort to resolve this quickly. I can't say that I'm super angry they didn't replace it for free and they did say they would make the camera in factory 'new' spec (so I'm hoping the bottom plate does get replaced also). I'll update once the camera has been shipped/returned, I paid for it today and was told it would start being worked on right away (15 business day turn-around). Here is a pic of the sensor I took at the dealer with an EPL-5/60mm. I have one of the overall camera I'll put on later as well. Hey the EPL-5 has decent IS performance, this was 1/15th of a second! The dust/spit particles on there were almost entirely from me and the few guys at the shop checking the camera out, I promise it wasn't that dirty before that day.
