Hi, I have been lurking for quite a few months. Long story short I take a ton of pictures with my D700 but was looking for something lighter and smaller. Picked up a O-MD EM-5 a about a week ago, and I have been generally pleased with it, after setting the menu system up some. Till yesterday. I take the SD card every night and grab the pictures off of it, then put it back in so it is ready the next day. Yesterday when I turned the camera on, about 1 second before I wanted to take pictures of my son acting crazy, the camera said there was not a memory card inserted. I did not notice the message till after I thought I had taken 4-5 pictures. (which didn't save) Turned the camera off, pulled the memory card and put it back in. Turned the camera on and it was fine. The exact same thing happened to me again today. I don't see the error till I stop trying to take pictures and all of those chances are lost. I suppose some of the blame should rest on me to see the message before I try to start shooting, but the memory card is seated properly and empty and ready to take pictures. I have since updated the firmware to 1.6. Has anyone else run across this issue? It's driving me crazy and making me want to go back to my D700. I am using a used PL1.4 and it only seems to rattlesnake every once in a while. I am still getting used to the skin tones I am getting. Thanks.
