K-3 II Panning Shake Reduction

There have been quite a few threads discussing K-3 & K-3 II AF performance; but I'm interested in one particular aspect: panning.

Background - I shoot motorsports fairly frequently, and love slow (<1/80) shutter speed panning shots. I'm currently using a K-5, and more often than not, a 60-250mm that I prefocus. I generally fire a short burst, and my keeper rate is...OK.

I'm pondering the upgrade to either a K-3 or a K-3 II. I've weighed the other differences; but none are as potentially important for this use case as the shake reduction while panning.

So, for those who also shoot fast-moving objects, man-made or otherwise, do you think the panning SR is good enough to tip the scales in favor of the K-3 II? How effective is it in the real world?

I wasn't aware any Pentax had SR dedicated to panning? There is no option for vertical or horizontal stabilization. I may be wrong here but i think you should be turning SR off while panning.

It's a first for Pentax. When it detects panning, it shuts down stabilization along the axis of motion, and maintains it in the other axis. From the Imaging Resource review:

"At the same time as improving the efficacy of the stabilization system, Ricoh has also made another change which should mean that you get better results when shooting moving subjects: The Pentax K-3 II's Shake Reduction system can now detect and account for panning motion, stabilizing your motion on all but the axis of the panning motion."

Pretty trick, no?

I had a K7 then I recently got the K3ii. I also do quite a bit of motor sports photography and it's panning detection works well. On the K7, I had to turn the SR off in order to get clear panning shots as the SR was countering the panning, making the image significantly worse. When I would take my people shots, I would forget to turn it back on, another issue. With the K3ii, its no longer the case. On top of that, I can take panning shots handheld, which I couldn't do before. The panning detection doe work and it works well!!

Does it work the same on the K3 ?

the 8+ FPS will likely do more for your images than the shake reduction. i use a k3 and shoot motorcycle racing constantly. rarely go as slow as 1/80 but do a lot at 1/125.

as far as i know the k3 doesn't have panning shake reduction, so it must be a k3ii thing?

I believe the panning SR is part of the upgrade from K3 to K3ii. The other upgrades are the GPS (which replaced the built in flash), AstroChaser mode and pixel-shift high res setting.

Thanks, JC!

I'm the world's most absent-minded shooter; so simply not having to remember to switch it is a huge plus.
