Hi Bruce Thanks for the clarification. Speed does not seem to be such an issue with most of the photos I see from you to let those fine A lenses go? Greetings Markus

No need to do mental conversions in your head. You put in the actual focal length of the lens. In my simple testing I found that for the A 35-105/3.5 and A 70-210/4 zooms, that SR worked markedly better when the correct focal length was input to match the shooting focal length. The downside to that is, using zooms with SR is not as easy and quick as I would like. It sort of pushes me towards considering more modern ones. -- Best regards, Bruce Wednesday, April 18, 2007, 8:47:04 AM, you wrote: MM> I did it wrong then so far by telling SR 77mm for a A 50mm macro and 42 MM> for the 28mm?
