Thanks Jeremy and Bernard. I will reshoot something at f8 and in the 120mm range, tripod and release ( as always) Unfortunately my camera can not shoot with ML. It is only a means to clean the sensor. My question to Bernard is: how large would you feel comfortable printing your lovely pano at?
This one was shot handheld, but is still pretty sharp. A width of 1 meter should still deliver very good perceived sharpness on this 50+ megapixel image.
