Originally posted by Sunday I am reading one must disable the shake reduction system when using a tripod. I understand it may not be necessary using the SR together with a tripod, but cannot understand why it should be disabled.
Does it affect the image? Can somebody explain in technical terms, other than "it's written in the manual"?
Thank you.
Without knowing the full technical details of "how it works" I know the basic concept is that it detects vibration, and moves the sensor with oscillation calculated to counter the movement.
When SR is left on whilst on a tripod It basically introduces slight shake to the sensor as it is trying to find/compensate for shake that isn't there. But If you are ever using a tripod you should be using remote shutter or shutter delay. I know that even the 2 sec shutter delay automatically turns the SR off.
It should also be turned off when using techniques where blur is desired, eg panning technique.
Have a look at this
HERE (post 9 & 11) for the results SR can have. The photos here were taken by a lens with Image Stabilization (IS) but it works on the same principles as SR.
I hope this covers in enough detail for you.
