The Leicaflexes have one of the shortest (possibly *the* shortest) shutter lags of all mirror flipping SLRs, one of several ways in which they're somewhat "rangefinder-like".

The R series are quite different cameras, so comparisons are meaningless.

Haven't used the R6, but the R4 & R5 have somewhat longer shutter lags than many cameras I've used.
