EM5 Mk II shutter problem?

Very strange. I don't know why it would not also affect video however.

I would try a different SD card, different lens and clean the contacts, update to the latest firmware (if it is not already at the latest), and see if that solves the problem. If not, then it sounds like a hardware problem.

Thanks, yeah, I should do all those things - I did try a different lens, no change. Updating firmware now, Updater can't find the camera :-|

Are you using the latest version of Olympus Workspace for updating the firmware? Did you get the LCD screen for Storage on the back of the camera when connected to the computer? Assuming your USB cable is good, not getting the back screen on the camera would probably imply a hardware problem.

Mechanical or electronic shutter? The samples don't present as any mechanical shutter issue I've encountered. Odd though, that video looks normal.

My first though is an electronic failure of some kind.

Good luck!

Ok the firmware update was done (my issue was that I didn't "OK" the storage option), on the body and 2 lenses. Process went as expected, with OK on the screen at the end. No change to image quality....

Unfortunately that does not sound good. The only thing that has ever given me corrupted images on my E-M1s is a bad SD card and problems with the camera writing the image to the card.

You might reformat your SD card with the


If a different SD card gives the same issue, it would appear that a repair is needed. I don't know of any easy way to clean the camera SD card contacts, but I doubt that is the problem.

FWIW, these 'distortions' are not the result of of memory card errors or bit corruption that occurred during 'transport' as these would result in errors during decoding the JPEG data. So IOW these aberrations we see in the photos are encoded into the image.

Olympus SD card problems are not always as expected and software used to process the files can result in different results.

For example the first image below appears the same as a RAW image when imported to LR as it does in the exported LR jpg. However, if you open the image in Olympus OV3 it will not have the distortion and the exported tiff/jpeg even when opened in LR will not be distorted.

The distortion is specific to the particular SD card and never happens with other cards RAW/TIFF/JPEG images in either OV3 or LR. The first image is the LR RAW file conversion, the second OV3 converted to Tiff and the Tiff exported from LR. My problem SD card randomly produced corrupted images of the RAW and jpeg files in Adobe but not in Olympus software.

I do agree the specific problem is probably not an SD card problem. However, I would at least want to eliminate any possible SD card problems before sending the camera for service.

I have no reason to doubt your observations, however I base this on examination of the JPEGs in OP, these are perfectly valid JPEGs with no signs of any bit errors.

So, I see a lot of JPEGs that are corrupt due to memory card problems, or got corrupted during transfer at some point (bad contact, bad cable etc.) and ones in OP are not like that. My own JPEG decoder is designed to pick up such anomalies. So I am fairly confident these files are as written by the camera.

I'd like to add that these JPEGs embed restart markers, I think all modern Olympus cameras do, don't know if this is an option you can turn on/off. Which is cool by the way because it contains corruption to a very small area. Now IF aberrations would be the result of bit errors due to a bad cells for example, or bits flipped while copying etc. they would not look like that as the first restart marker after corrupt bits would recover colors etc.. You'd not see those green bands for example.

So IOW these pictures may not be what you expect them to look like, however it's not due file corruption. These were encoded erroneously to begin with IMO.

Do the images look like this when viewed in the camera? I'm wondering if file transfer might be the problem.

Yeah they are the same in the camera. I am aware that the images viewed on the camera were the .jpg versions, I was holding out some hope that the RAW versions would be intact - but no such luck.

Yeah, tested with another card, same result. Also tested with mechanical and electronic shutter, same result. I guess it goes back to Olympus...
