The 120mm f/2.5 APO-Macro-Summarit-S is ostensibly a macro lens, but it should be equally at home for any kind of work. It is equivalent to a 96mm lens on a full-frame 36X24mm DSLR.
The 120mm f/2.5 macro affords close-up capability to 1:2 reproduction ratio, with a very good working distance of 57cm from the film plane.
Leica states that “a floating element ensures unmatched performance from infinity to extreme close-ups”. Which sounds terrific, since it might mean exception performance for landscape applications. But 1:2 is hardly an “extreme” close-up, but presumably it means the 1:2 close focusing capability is also excellent.
The 120mm appears to offer the highest performance of the S line, according to its MTF chart.
