When do you turn SR off?

My default lens is a 35mm prime. 1/f rule of thumb (ignoring SR) says that my shutter speed should be 1/50 or 1/60 of a second. If I'm outside I can get 1/200 of a second or better easily enough. At what point does in-body shake reduction cease to have any effect?

Presumably there is some point at which SR actually makes things worse. What sort of multiple of the 1/f speed would we be talking about?

For me, the only time it's off is when I select self-timer mode

wrong question.... IMHO.... the question is "When to turn SR on?" and for me it is only when absolutely needed..... I prefer using a tripod before resorting to SR...
SR is only for low light handholding situations such as wedding receptions where the tripod would be too cumbersome for candids...

Seriously, why turn SR off when using it handheld?
My SR is always on

My SR is always on -- it turns itself off in certain modes (self-timer, mirror lock-up, remote trigger). It should be off when using a tripod -- it can make it worse, but when I use a tripod I usually also use mirror lock-up and a remote so it turns itself off. So if you have your camera perched on a rock or something you might turn it off even if you are still "handholding" it sort of. (I much preferred the exterior SR switch on the K10D where I could flip it off easily and also easily see if it was on or off.) It is also not much use for macro where you get "in-out" shake that actually makes a difference. If it is handheld and your shutter speed is already very fast compared to focal length (x5) then it really doesn't matter whether it is on or off -- I've done enough personal tests to determine there is no particular reason to turn it off most of the time.

My SR is also always on. The only time it comes off is when I am shooting on a tripod (turns off Automatically with self timer) and when I am using the panning technique for moving stuff (which I do manually).

My SR is always on EXCEPT:

* tripod or timer usage
* macro focus distance
* twisting MF zooms
* forgetful negligence

Well, on the K-x, she SR actually can play tricks sometimes, and ruin shots taken in otherwise reasonable conditions (1/100, in vertical position, focus at infinity).

Ok, if you wish to limit discussion to only those cases where a tripod is used, sure, don't use SR. But in the cases where you are not using a tripod - which is the vast majority of shots taken by the vast majority of photographers - then SR should geneally stay on, as it will help even in situations where you might not expect, and will rarely if ever hurt.

What about 1/500 or 1/1000 and faster shutter speeds. I have a "sport" user mode set up on my K-5 where I use 1/500 or faster, and I'm considering turning off SR for it. I've heard advice for canon and nikon shooters to turn off their VR/IS (on their lenses obviously) off at these fast shutter speeds, so I wonder if it applies for us too

I also have a "panning" user mode and SR is off for that.

I don't wish to limit the discussion.
I factor my own human behaviour into my process. I use a tripod as often as possible... by keeping the SR off I never forget to turn it off before mounting the camera onto a tripod... it's really that simple for me. SR is something I resort to when needed, and since it's only needed in lower light, environments where you want lower iso and slower shutter speeds.... and the tripod is too cumbersome... I rarely use it.
in fact... I'll use flash in those conditions before turning on SR.

boils down to habits, I guess...

MIne is on all the time, except on a tripod. And SR helps when I shoot because I have a problem where my hands shake uncontrollably most of the time.

I tried RioRico's, in turning it off for my macro shots, I couldn't tell any difference, so I leave it on for those shots too.

Do you think he SR will be less tricky? I think K5 has a "he" SR, I find it less tricky than K-x which was always playing tricks, but "she" was very cute! I still regret selling her

Not that often. Because Pentax removed the switch, and it takes too much time to do it in menu with a big chance to forget it there, while the dedicated switch is in front of you all the time. I hope they return it back in next models.
