OPS and Focal Length


If I'm using an old manual lens with my GX10/K10D and want to use OPS do I put in the focal length of the lens or the focal length x 1.5?

For Optical Picture Stabilization aka Shake Reduction, you enter the ACTUAL focal length of the ACTUAL lens you have. And forget you ever heard of Crop Factor. (I like the German term, formatfaktor.) Putting a lens on another camera does not change its focal length. A 100mm lens is a 100mm lens, no matter what size sensor/film frame it is feeding light to. Smaller frames just see less of an image circle, that's all.
