My e-pm2 and shutter shock findings....

All testing done with one target,at one sitting, using same method...

Oly 17 f1.8  - None observed

PL 25 f1.4 - None observed

Kit lens 14-42 & 40-150 - micro and regular four-thirds - observed from 1/60 to 1/200 shutter speeds

Sigma 30 & 60 - same as kits

Thought it interesting that I didn't observe the "ghosting" with two of my lens.  Going to have to test with my Panny G2 eventually...

Anti-shock settings?

Was that with or without engaging 1/8 sec anti-shock?

Re: My e-pm2 and shutter shock findings....similar to your findings..

Ted,

I also noticed, with the kit lens, at slow shutter speeds a blurring. Originally thought it was my fault with holding the small camera steady. Did a bit of digging on DPreview and turned on the anti-shock setting and whatdayaknow- blur went away. Also experimented with turning off image stabilization still looking at results on that. Overall its not a big deal just something to be aware of. Any camera will have certain quirks and so it goes.

cheers and beers,

Joe

Off, may turn on and test later but will utilize with susceptible lens going forward.

Will try the anti-shock next time with the Sigmas, been dealing with digital camera "quirks" longer than I care to admit!  😁

My own tests with the E-PM2 showed:

Increased sharpness with anti-shock set to 1/8 sec.

When IS is turned on, there is sometimes quite significant blurring regardless of the anti-shock setting.

Returned my e-pm2

I had bought the e-pm2 from newegg's eBay promo... yes the bargain $200 price! Yet I returned it.

I concluded the shutter shock could not be avoided. I turned off the IS, updated the firmware and enabled the 1/8s shutter delay... not matter what I did, most of the images were blurred.

However, once the camera "Hits" the image right, the images were amazing, DR was fantastic. But the hit rate was very low (I imagine less the 20%), and I could not trust the camera. I would still grab my old GF1 if I had to have a "keeper" image.

When I had the EM5 a couple of years ago, I never experienced this kind of behavior. The keeper rate on the EM5 was higher than any camera I've ever owned.

"Hit rate 20%" huh?

Hi Sam,

Wondering what you are photographing with a hit rate of 20%? My epm2 is very good with no problems with focus, exposure etc. Indoors its fine, in those conditions where its warranted I use the anti shock setting. I'm curious about the  20% though...

cheers and beers,

Joe

Re: "Hit rate 20%" huh?

I think the shutter shock was a huge part of the equation. I tried to capture 4-5 images in a row for each scene, and consistently in 2-3 of them you could see shutter shock effects. Again, once the camera hits the image right, it's fantastic. It was more frustrating to see the good images coming out of this little camera, and knowing that it IS capable of getting them... yet it doesn't most of the time ;-(

I went out several days, and compared my old GF1 with the e-PM2, using the same lenses, back-to-back. None of my GF1 images were blurry (granted the e-PM2 has much higher resolution), yet MOST of my e-PM2 images were blurry ;-( The Dynamic range of the new sensor is amazing, and as I said once the camera hits the scene right, the images are MUCH better than the GF1.

For a casual / family user the e-PM2 kit is a FANTASTIC buy at $200. But, I already had that, and wanted the new camera for the sensor, and detail/landscape work. Shutter shock takes out a lot of the detail, and basically turns it into a 6-8MP camera, with great Dynamic Range, and fantastic high ISO capability.

e-PM2's pros:

  • Fantastic Dynamic Range
  • high ISO / low light capabilities
  • Small
  • Nice kit lens

e-PM2's cons:

  • Shutter shock even with IS turned off, and 1/8s delay
  • Small LCD (in practice it's about a 2 inch screen for 4/3 ratio image)
  • external flash
  • Tight mount (one of my lenses would not mount on the camera)

Ted I didn't see any photos but here is what I experienced when I checked my camera. Are they similar to yours.

Re: My e-pm2 and shutter shock findings....

Nope, didn't see any evidence of ghosting on the text you posted unlike what I found with my camera and lens combos which did exhibit the anamoly.   Wish I was so fortunate with all my lens I checked, but I'm happy not to have it with two of my lens!

Well I only checked one lens but Im going to check them all. Did you use a tripod. I know if I turn off IBIS I get double images at low shutter speeds.

Sam,

I've had the EPM2 and kit 14-42 and 40-150 for about 1 month and have experienced none of this shutter shock to my knowledge.

Here are a few examples using both lenses handheld with IS on and no enabled shutter delay.  Are these not sharp?  Maybe you have a bad camera.

Trying to help,

Joel

Re: My e-pm2 and shutter shock findings....

IBIS on for all testing, I only use tripods for portraits but have no reason to expect a difference based on other's findings along with my results...

Re: Returned my e-pm2

I may have had a bad camera (copy). Either way, it was returned.
