Interesting take down of the rather reliable line of cameras (after early R4). Prices are not at all related to reliability, Rs are not Ms, never were. Their connection to Minolta does not help hold prices either, especially when even today people talk nonsense about that mix of technologies. Some partnerships die their own death, only because they were ill advised, ill marketed, and with too many expectations.
Handling wise I feel Rs where at top of the game, then and even today. Comparing to Canon F1 or Nikon F2, I don't see how anybody, or most, would not appreciate body's shape and overall ergonomics.
SL was meant to be what it could never be, but Rs I think had only one problem, brand name and pricing that could not put it in a completion with any major player in SLRs of their time. Can't sustain production competing with a product at multifold pricing premium with nothing to little more, outside of brand, to offer.
Still, thanks to all that marketing failure, many of us can use an R at rather affordable level (nix the top lenses that is).
