Thanks! I suspected the f4 with the mb20 would be lighter, while heavier with the mb21. Got mine as a f4s, but it's gone back to a f4 with the mb20: makes it a much more "luggable" proposition!
One thing I know for sure now: the f6 is much, much lighter. Not surprising of course: it's missing the mb40 at the bottom! :rolleyes:
fm2n/md12 is a combo I'm starting to like more and more. Still prefer the fe2/md12, but it's growing on me. The last 4 b&w rolls have been taken on that and the "feel" is just peachy. Dang: I need more time to take all these babies out!
