Shake Reduction is outstanding.

Please don't judge the photo composition or subject It was all I had available in the backyard during a break in the crappy weather.

The shake reduction in the K-1 is over the top good during initial tests.

Here, I have my Sigma 70-200 mounted (it's internal SR off). Handheld in a breeze at 180mm, 1/25sec (yes, 1/25 not 1/125) at F11 ISO 200 and with the frog the focal point.

Look how sharp that frog is! Pixel peeping, there is barely (any?) hint of blur...at 1/25th!

I'm quite impressed!

3 stops. 1/180 is in theory what you need, 1/90, 1/45, 1/22.5...

Pretty much expected but awesome to see it works.

Exactly. I was excited for a real world test to see how it compared to the on paper specs.

It sure is. I shot pics with the F fisheye at 1/30s, in live view with the camera held far above my head. Razor sharp results. Plus, the tilting screen was a godsend when shooting like that!

Could you try shooting handheld with a 1s shutter ?
I remember seeing a Nikon lens with shake reduction where shooting handheld at 1sec produced minor blur. Just to compare. Thanks!

What lens? To try you need to know the focal length to be able to compare...

Very true. It was a 85mm lens.

ISO is important too, it has an effect on sharpness.

Anyhow, 85mm is 47% shorter than my shot at 180mm so I'm not sure that would be a fair comparison (if it can't pull off 1s at my previous specs).

That's 6 stops in theory. That would be pretty impressive.

Yes I missed the focal of your shot for some reason
I think it can pull off 1s shutter with mild blur at 85mm looking at your results. Indeed impressive !

See if at 180mm you can pull off 1/3 sec with mild blur. That would be 6 stops from 1/180.

Having done a bit of rudimentary testing, I've set the FX2 button for Shake Reduction [On/Off]. Only use SR when you really need it, i.e., slow shutter speeds, less than say 1/Focal length. Apart from that, yes it is outstanding when required.

It is brighter today than yesterday, so best I could do was 1/10S, F16, ISO100 and 180 and 200mm

Chimping the photo at 100% (no time do download at the moment), I see just a bit of softness. Wouldn't exactly call it motion blur
