Sometimes the bird is just too darn far away. One of the things I really like about the mirror lenses is the (lack of) mass; I can hand-hold the 800. I don't do much better than 20% usable, that way, but it makes a number of opportunistic shots possible. As the high ISO sensor performance improves, I think the f8 and f10 solutions for very long lenses will get much more usable than they used to be, too. I don't know if this will carry over into someone electing to make really long and relatively slow refractor lenses or not. -- Graydon -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
