How to set Shake Reduction with macro lenses?

I have a set of macro lenses that screw onto the front of my M series lenses, allowing them to be used for closeup photography. Not quite macro, but close enough for me for now.

They are a set of three, numbered 1,2 and 3. I have used them alone, and combined.

How do I set the shake reduction? Say I am using a 50mm lens, is the shake reduction still set to 50mm? Or, should I just turn it off?

Thanks for your help!

Eric

Eric,
Set SR for the focal lenght of the lens. Those suplimental lenses don't change the focal lenght. they only reduce the working distance, allow closer focusing.

Eric, Dave is right, but the classic rule of close-up photography is righter: use a tripod or other support! Then, of course, you won't need SR and you'll get the sharpest possible result out of either macro lenses or close-up diopters.

Eric,
I forgot to mention that the closeup lenses come in different diopters to change the mag ratio.

Thanks for the info!

So, closeup lenses don't change the focal length, and I should be using a tripod.

And if you are using a tripod, you shouldn't use shake reduction, and you shouldn't need it.

I'll just go ahead and disagree with everyone, or maybe not. If the close-up lens reduces your field of view (i.e., magnifies the image), then you should modify the focal length you set on the SR accordingly; if it simply allows you to focus closer, then you should be OK not changing anything.
