I have nothing so big either. I'm familiar with the "prime over zoom" concept, Bob. Actually, Pop Photo's SQF tests of both the DA*300 f/4 and the DA 55~300 /f4-5.6 showed the 55~300 as producing much superior resolution results at all comparable aperture settings. I realize, of course, that's only one test and doesn't account for sample variations. Due to its light weight and zoom extension, the DA 55~300 almost demands a solid rest.
