Originally posted by DougLee I appriciate your comments Swift1, as much as the 55mm impresses me, I don't think I want this to be as wide as I can go and for now I can't afford to get both, so I think the 45mm is in. On the Tele end, I know the newer 200mm is supposed to be excellent but I worry about the max apperiture of f/4 making the viewfinder too dim when in shade or indoors. Do you have any thoughts on viewfinder brightness when your 90mm is mounted vs your 200mm?
I have only ever used the 200/4 mounted on a tripod and using the Waist Level Finder so I can't really comment on viewfinder brightness. You could always set your 90/2.8 to f/4 and set the Auto/Manual switch to manual and play around with focusing. The DoF will be different than a 200 but that will give you an idea of the brightness.
If it were me and I was planning on mostly shooting handheld, I would probably go with the 165/2.8 as the extra stop and slightly shorter focal length would help with handheld shooting.
