We are not talking about exposure, noise, light admittance, depth of field, etc. its about keeping a sensor in a given spot accounting for momentary movements in all axis. The accounting of movement to have a clear, crisp, sharp images. So the notion of 6x, 8x, etc is meaningless. Yes physics does have a hold here. It appears that Pentax has had a massive amount of improvement with their algorythms and shake reduction technology with the release of the new full frame model. Yes the m43 has a little bit of wiggle room do to not having as big of a sensor, thus shaving a little bit of weight off the sensor,but it is just a crop of a larger sensor. Unless someone knows exactly what the weight difference is, or the compensation rates, etc. of the mechanisms/ sensor, the difference between the two are meaningless. What matters is if the photographer is happy with his camera, along with getting the results they desire with said tool.

Would it though? I mean there is much more involved then crop factor. Just because there is a crop factor of two, doesnt make there be a crop factor everywhere else. The weight of a m43 is not half as heavy, the mechanism is not half the size, and it wouldnt mean that to get the same movement in the location you need to have double the shutter speed or half the shutterspeed. So to say 16 seconds and 17mm well its not realistic....
But in general, i think we can say if the camera can stabilize for the same amount of time with its shutterspeed, with the same person, with each camera having the same field of view only, then id say its on par with each other.

Impressive, nice image

I did some more testing outside this time, and I tend to agree with your statement on not sure on what it would be useful for. conditions were not the best super sunny and really windy, but I got some shots off. on average though between the wide end and the long end Id say it was about 30%-40%. and that was using the image I posted before as what acceptable for this test would be. In reality though I wouldn't claim any of them would be great outside of just posting on facebook. Long Exposures belong on a tripod.
Ill stand by my original unbiased comment that the Olympus has a great stabilization system, but I would say the one for Pentax is a tad better.
Oh and one last comment on the long exposures, outside of doing these tests. Either with the Pentax or Olympus, Not sure why anyone would want to look at a blank view finder for 2 seconds anyway. Just a thought :lol:

Something came up today to where I wasn't able to do the full test, I did manage to get some time to snap 8 images to at least show something for today. It was nothing special with the Olympus at 25mm (35mm equivalent being at 50mm). With only capturing 8, Id say 3 are very useable, 2 are passable, and 3 well I label them as my head still hurts from last night and my vision is still spinning.
I still have to figure out how I will post them, or at least make a contact sheet to show the images at once and upload that, but here is one of the acceptable ones
shutter priority, 2 seconds, camera picked the remaining settings, soooc JPG with no processing.
One more thing, I did not use a tripod, or prop myself up against anything. Also I would not normally have a shutter speed this long with out a tripod.

Ok. Weather today looks like it will be good, hopefully it wont be windy. To make the tests even. Ill take 10 shots across each the focal lengths( lets say 24, 50, 100, 150, 200 35mm equivelant) have the camera on shutter speed priority at 2 seconds, there will be no tripod or anything to brace myself on.

Ill need to reshoot the photos, but preference on focal length?

Its hard to believe, but yes id say consistently. I agree that the human body is not that stable, so it goes to show how good the stabilization system is [emoji6]
There is also other factors that come into play and technique and breathing are important

That is true, they have, and it works really really well. The pentax stabalization though i feel is a little better as far as ibis is concerned though.

Technique plays a huge part in it. How you breathe, how you hold the camera, etc. its hard to believe that the Oly delivers a consistent 2 seconds but it does. Might not be the sharpest at the telephoto end of the spectrum, but it is passable if one needed to use a long exposure. Again ive had consistent results, not propped up against anything using the olympus omd em1ii and the oly 12-100 f4 pro lens. Ill see if i can find the image but if not ill take another, it was at 100mm with a 2 second exposure.

I was able to get 2 seconds hand held with the olympus at 100mm focal length. As far as what i had with the k1, ill need to go back and see what was the shutter speed i had with that one when i was comparing the stabilization between the two.
