Hi Tim I used SR today with the monopod and the K10D and Pentax 70-210mm at 1/90 and it worked very well. greetings Markus

I feel pretty confident that SR does not have any effect using critical shutter speeds, but it might have negative effect using other speeds. I'll probably report back on this later.

I was really hoping it could give me an extra hand. The manual tells me to shut SR off on tripod, but I have been hoping it was otherwise in a gimbal mount. After getting the camera I have been testing a bit, but haven't been able to draw any conclusions. So I decided to do a semi scientific test. I used a K-500/4,5 at 1/30 with a Velbon CF-630 (a medium class tripod) at my lawn. It was rather windy, so I believe the test was rather realistic. What I did, was simply to shoot 75 shots with SR on, and then 75 more without. At both series I used basic tripod technique with one hand leaning on top of the setup, and my nose glued to the LCD. I put the files in a random queue, to make sure I wasn't biased when judging the results. I scored them in three categories: 1 junk, 2 so and so, and 3 potential keepers. The result was disappointing I'm afraid. I found no impact of SR whatsoever. It may be a bit early to make drastic conclusions based on this, but I do know that SR does not affect the result at 1/30 with that lens. I may try again at other speeds and lenses with other weights. But I don't really believe it will be worth the effort. The positive thing is that the test also suggests that there is no reason to be afraid of leaving SR on with gimbal mount at tripod. I believe the manual is over conservative on that point.
