Do you ever turn SR off?

Joe,
I only turn it off when using a tripod or copy stand.

There is currently a debate about whether SR (or AS, SSS, IS, or whatever you want to call it) should be turned off at certain high shutter speeds too.

There are some that argue that at high enough shutter speeds (for example 1/500sec. or higher) that a person can take the photo faster than the SR can adjust for. In other words, the SR can still be on the move while the shutter is finishing taking the shot. Ergo, some blurriness is actually being caused by the SR mechanism being too slow in moving.

Wow! This is a 3 year old thread being resurrected but I'll add a thought I don't see mentioned. I always turn SR off when I have mounted my Sigma 17-70mm f 2.8-4 lens. The OS built into the lens is superior to the SR in the camera by 1 to 1-1/2 stops so I use it.

If the SR is "too slow in moving" then it won't actually effect anything when taking photos at high shutter speeds - since by your words, it wouldn't have moved so much by the time the shot has been made. Then, it's no different from leaving SR off. So, may as well keep it on.

Vylen: It ends up being a similar effect to the shutter speed not being quite fast enough to stop the subject's movement, just in reverse.

I was watching a podcast earlier today and heard it's best to turn it off when using a very slow shutter speed (consequently when it's on a tripod anyways)... just for the simple fact of overheating and battery drain.

Alizarine · 03-30-2011, 04:01 AM

Hmm I don't turn it off manually...

the camera turns it off for me when the SR "isn't allowed" for the situation, such as when shooting in HDR mode in the K-x

so in a way... I don't turn it off~

I rarely turn it off on my K-r. I have noticed that when I change the setting so that I can use a wireless remote shutter release, the camera turns SR off for me. Cool feature!

I see SR as gimmick of some sort...... I see no difference whatsoever it being on or off on K100D and Kx.

I have yet to notice anything of the sort...

Mount a 50mm lens, select, say, 1/8s shutter speed, handhold the camera...post the result with and without SR.

Or a 200mm+ lens and shoot at 1/100s.

I've done both--neither are easy (if not impossible) without SR.

For those of you that do turn it of, except on a triod, why do you? Why on MF lenses? Why when panning? Why in bright light at speeds of 1500?

I turn it off when it`s on a tripod or when I`m panning simply because PENTAX say I should and they know more about their cameras than I do ( although it`s amazing how many people on this forum know more than PENTAX.)

That will not help much, the same servomotors used to lift and hold the sensor when SR is on is used to lift and hold the sensor when SR is off.

I woud like the option for always on SR rather then SR only when half press shutter and then waiting that few moments while the SR kicks in and the SR icon lights up.

KFrog · 04-01-2011, 08:49 AM

I almost never turn SR off on my camera except when it's on a tripod. I'm sure there have been times when I forgot to turn it off, but most of those times when it's on a tripod I used the 2 second delay and the remote which turns it off anyway.
