I wrote that poorly; thanks for pointing it out! You are right; the longer (actually all) 67 glass is quite reasonable speed-wise. I really have no complaint in that regards. Particularily, I think that the 1000mm reflex lens is the cat's meow. Outer bayonet mount ... but it doesn't matter since there is no aperture coupling anyway! Built-in filters. Built in ND filters seperate from the color filters. f/8 versus the f/11 or f/13 commonly found in 35mm reflex lenses. Too bad someone (pentax preferably) doesn't make a 35mm reflex lens like that! Speed-wise I was refering more to the shorter lenses. A 1.x normal or short tele would be nice to have when it is darker. However, perhaps the DOF on such glass would be so short as to be unusable. That is soemthing I didn't consider in my previous thoughts. I just realized that most of my slow shutter speeds have been due to DOF issues, which a faster lens won't do anything for.
