Its a superb all round lens with a particular focus on landscape work with a added ability to focus closer than many 24MM lenses, this lens can focus to 0.27m, compare this to a Nikon 24mm f2.8 which focuses to 0.3m.
(the lens has no meter Scala to read. Focusing is done with the camera used on monitor or viewfinder). It must be focused manually. (The lens has no autofocus!). The lens can be optional with corresponding adapter (charge) used in digital system cameras.
