Yep, there's a good reason why the first additional lens I bought for my RB67 was a 250 -- other than the price being attractive. It's exactly the same magnification ratio as a 135mm compared to 50mm on a 35mm camera -- long enough to matter, but not heavy enough to always stay home. Not sure I'd take that camera to the zoo, though. Hard to get it under forty pounds with lenses and backs and including tripod. Which is the main reason I'm still trying to find money for an M645.
