So, I'm afraid I might stir up a hornets nest here, but here it goes...

I wanted to get back into micro four thirds, so I just purchased a used ep5, after reading extensively about the shutter shock issue. I convinced myself before making the purchase that the problem was probably overblown, and that I could overlook it if I did encounter it, etc, etc. I really wanted that ep5. It looked beautiful.

After receiving my camera I did my best not to look for it, never zooming to 100%. Then I noticed some photos I took of my cat with the 45mm 1.8 looked a little blurry, so I hit the zoom button in Lightroom, and... oh crap, vertical doubling so bad it made my eyes hurt.

So then my inner nerd couldn't resist the urge to setup a test scene to see just how bad it was. It was bad. I like to think I'm not too picky about sharpness, but almost every photo shot between 1/80 and 1/250 looked unacceptably blurry. If I was evaluating a lens, I'd return it without hesitation. Everything at 1/400 was tack sharp. Shots below 1/80 did pretty well too. Shot the same scene with my lx7 and d90, and those were nicely sharp also (to reassure myself it wasn't my technique).

I'm attaching two 100% crops from my testing, both shot with the 45mm 1.8. The blurry one was shot at 1/250, and the sharp one 1/400. I did 10 shots at each available shutter speed between 1/80 and 1/250, and I'd guess 50% to 75% of the shots looked like this example. Some worse, some better. Maybe 10% were sharp.

So, I'm most likely returning the camera. And I'd really, really like to get an em5 to replace it. But will I be just as disappointed in the em5? My reading indicates that shutter shock isn't unheard of on the em5 either. But it doesn't appear to be a big enough problem to warrant being mentioned in the review here on DPReview, like they did with the ep5.

45mm, f/2.8, 1/250, ISO 200


This looks more like a simple case of miss focus to me, as in attaining focus lock but then moving the camera backwards or forwards slightly before pushing the shutter all the way.

That looks like prototypical shutter shock to me. Much more vertical than horizontal blur. Certainly not a matter of misfocus.

Do some test using a tripod.

If you want to know how shutter shock works when shooting hand-held, you need to test hand-held.
