Leica always stated the framelines (prior to M8) were set for the closest distance the lenses can focus (70cm up to 50mm, 1m for 75 and 90, 1.5m for 135) plus the amount normally cropped by a cardboard slide mount. So my impression from using the M8 briefly was that Leica just lowered the magnification but didn't change the framelines' respective proportions, they just forgot that with digital nothing is cropped by a slide mount, hence the appearance of a greater difference between framelines and capture. Either way, my 20D doesn't show fully what's captured either, except unlike the rangefinders what's outside the viewfinder is blocked from my view. Would that I could afford (and could carry) the 1DS. I love my old Nikon F for it's 100% viewfinder! All told as Jaap says, once you get used to it and know instinctively how much outside the framelines you get, it becomes a non-issue. Used to be, a lot of people claimed they could just use the M framelines as is, but I think that was because by the time they got the film developed they forgot exactly what they'd framed 😀
