Got my e-m5 today took some shots and after I transferred the images to my pc I put the card back in without any indications of any problems. Took a few more shots but when I pressed the play button to review the images in camera I get this "no picture" or no image" prompt and it goes back to regular shooting mode. The remaining values don't change either so there's nothing being recorded. I had to format the card to get it to work. Again the same thing happens when transferring images but there is no error message which is what is confusing. Another card has similar results only the other card gets an error message and cannot be formatted in camera like the first. Both cards are class 10 Kingmax and Trancend cards which have been in use on my compact canon and GF-3 without any problems. I'm hoping I'll be able to rule out the camera. My PC has been running slow because it's near full capacity on the hdd and I'm using an external card reader plugged into a usb, not sure if those are factors. I've done a quick search to see if this is a common problem with the body and I'm still going through the results. Hopefully I can rule out the body since this was the last one they had at the store.
