I don't know about all that technical stuff, but I do know it's near impossible to get a Sharp shot of a little yellow duckling in the first days after hatching. I can get some of the yellow down sharp, but the lil' ducky's finest down is impossible to resolve, even with the best technique and lenses. The down must need over 100 lpm resolution, and it's pretty low in contrast to its surroundings, even on water reflecting a bright blue sky. Self-defense mechanism? Maybe predators have a hard time seeing a fuzzy yellow ducky also. -- John Mustarde www.photolin.com - This message is from the Pentax-Discuss Mail List.
