Extremely thin focus. This lens will bite you if you use it like a 50mm.

If you use a rangefinder, you’ll gradually master the 50mm perspective. A 75mm lens stands confidently at the gate of the telephoto world, and it will surprise you with the ultra thin focus. This is common for all Leica aspherical lenses – there’s a great gap between focused and defocused area, so it would be more interesting to use it in the middle distance, rather than close distance. If I only shoot in the Focus distance wide open, I’ll be amazed by the shallow depth of focus… but, that’s it. Because this lens is very sharp, once I shoot in the middle distance, the subject stands out thanks to the sharpness and the big bokeh of a telephoto lens. This won’t happen with a lens lacking of sharpness wide open. This is a very interesting lens, indeed.
