I bought this lens to use on my Leica SL as my everyday utility lens, given its length and macro capability. I use it with an R to M adapter attached to an M to L adapter. The output, frankly, is amazing. Colors pop. The Leica renowned microcontrast delivers a sharpness that I can only describe as emotionally powerful. All of this in a rock solid, 38 year old lens for less than a quarter of the price for a new M version!
