Its all relative, F2.8 is very slow for a normal range optic, but its a speed demon for an ultra wide or ultra telephoto.
I think the entire point of the 40mm F2.8 lenses are absolute minimum physical size with a reasonble speed. If it was an F2.0 it would defeat it's sole purpose for existance.... jco -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
