shake reduction
Wanted to reply to this even though I am not using a scope yet, am doing this experiment based on the idea of getting one this year. The attachment was taken with my Pentax K200D+300mm SuperTak+1.7xTC (stopped down to f/8 on the lens) on a monopod which was then shoved into a water bottle pouch attached to the front of my belt (had to lean hard down into the pouch to get more stability). The Shake Reduction was set to 250mm even though the lens focal length adds to 510mm (as I understand manually set SR, you do not add-in the crop factor). Bird was somewhat far, not sure, did not measure it off of google. Also, it is a 100% crop and was judiciously sharpened with PSP XII and Focus Magic. Not too bad for an experiment. Looking for an f/6 ED scope that is not more than 5 pounds in weight, hard to find. The new Orion triplet is f/6 but comes in around 6 pounds. Will be experimenting soon with the telenegative I tore out of that tamron lens last week.

Thats something i will experiment with, as i have a K200D too. Never thought of doing such a test. Soon as i stick my scope on, i set IS to 600mm
I'll try 200 and see what IQ is like on my monopod
