do I have a defective E-PM2?

Just received my "bargain" e-pm2 a couple of days ago. I've shot a few hundred frames with it, and I've gotten a bunch of these kinds of RAW files. Has anyone else seen this kind of behavior?

Same image from RAW+JPG files

The RAW file:

The RAW file

and now the JPG:

The JPG file

The card was formated within camera before taking the images.

Different cards, and different lens. It doesn't happen every time, but I'd say out of the initial 300 frames I've shot with it, I've seen more than 15.

This ain't good.

On the bright side, I got very fast warranty service on my PM2. I mailed it in on a Thursday and had it back the next Friday.

Do a few more tests, interesting (and I see, frustrating).
.

I very much doubt it is the cam.
.
As I understand it, JPGs are processed from the in-camera RAW (applying colour balance, sharpening exposure comp etc.) even when you don't keep the RAW.  I think that most (if not all) cams work that way? IE there's a RAW processor of sorts built into each cam ..
.
Can anyone confirm (or refute) that belief - with any authenticity?
.

Try, (say) After Shot Pro from Corel - it is free to test) as an alternative developer.

If it persists, email the images to oly and take the cam back to the retailer them to a cheap card and send it back ..

Intriguing ..
Changing/fixing the cam made a difference?  
What was it, software?

I use lightroom, and these images are exported from lightroom to a smaller JPG file that I've uploaded.

So far, my understanding is this behavior is NOT normal ?

My problem was not the same as the OP's. I was just relating that the warranty service was very fast.

It displays fine on the camera. I assume it maybe using the JPG file to display.

Here is another example. (with Oly 45mm lens)

I use my MBP retina's built-in SD card reader.

Importing to lightroom, I normally convert RAWs to DNG during import. In this case, either the DNG or ORF files behave similarly, and both have/display the odd artifacts.

thanks. I'm gonna update the firmware and see what happens. I won't try other RAW converters, since they are not part of my workflow. If the RAW's are having issues with Lightroom, then the camera will be going back... ;-(

I must thank you for the wonderful website you've created, and I tried to read most of it before the camera arrived.

My main question after using the camera for a couple of days is... How to deal with Shutter-Shock on these small bodies?

Turn on 1/8 sec anti-shock, and turn off IBIS. I had very good results with my EPM2 with that combo.

Thanks. So far I've tested the e-pm2 against my old GF1, and there is not much improvement ;-( Out of several hundred images taken of the same subjects with the same lenses (20/45/14-140), I see not much of Resolution improvement... I suspect mostly due to shutter-shock. (FW 1.0 with IS turned on).

I just updated the FW, and I will turn the IS off, and redo these tests. I hope to see better results.
