I am unsure which is which, unless you always list them in left-to-right order. Regardless, it is pretty amazing how well these old lenses compete in colour and sharpness. Only 28 Elmarit looks like it lags behind its compatriots.
I figure I would give the final update on what I decided. I sold both lenses on craigslist (got my money back) and used that plus more to buy a Canon 24mm F1.4L II. My reasoning is pretty simple. I have Leica primes at 35 F2, 50 F2, 60 F2.8 Macro, 90 F2, 135 F2.8 and 180 F2.8. 28 is not really enough of a jump from 35 to justify a prime. If I didn't have my Grandfather's 35 Summicron R (which I will never sell), I would probably just go from 50 to 28 (find a good V2) and call it good. Since the 24 Elmarit R is a minolta design and not well regarded (plus clips the mirror on full frame), it is not an option for me. I don't want to go to another brand really (a la CY Zeiss), because I will just have to deal with another kind of adapter (and I don't like cheap adapters, so it will cost $150 for a good Fotodiox pro) and possibly non-matching color. I didn't want to do anything nikon becuase they focus the "wrong" way (which is fine if all your lenses are that way, but if all your other lenses focus the other direction it is a problem). The 24 1.4 L provides a great fast AF lens as my walk around prime. It is damn nice too!
Oh Ya, it also has lens profile available in LR3 that makes it even better
