Descripción

Canon had a 1.4/24 mm lens with aspherical surfaces in FD style for its redoubtable New F1-camera system and Leica was thinking about such a design for their Leica-R system. The Summilux-M 1:1.4/24 mm ASPH. has been on the market since 2008 and is part of the current range of 1.4 designs for the wide angle group of lenses. The Leica-M range of lenses is rather complete as long as one has to rely on the mechanical coupling of the rangefinder and the select number of frame-lines in the viewfinder. Room for expansion lies in the area of very high-speed lenses and this Leica Summilux-M 1:1.4/24mm ASPH. joins the Summilux-M 1.4/21 mm ASPH. and offers comparable performance. At maximum aperture the 24 mm version is bit behind the 21 mm version, but one has to be very careful to note the difference.

In the not so distant past, one could hardly compare with decency two lenses with apertures so widely different as an 1:1.4 and an 1:3.8 and then only detect small differences. It is certainly a tribute to the Leica designers that the new 1:1.4 designs can be approached as fully normal lenses without making reservations.

The choice between the Summilux-M 1:1.4/24mm ASPH, Elmarit-M 1:2.8/24 mm ASPH. and and Elmar-M 1:3.8/24 mm ASPH. can be made solely on intended use and need for speed. For reportage, documentary, snapshots and location photography for fashion and portraits this is quite often appropriate. In these situations the high-speed allows a new type of imagery and combined with the compositional advantages of the wide-angle, the photographer is to blame if the pictures are not visually pleasing and arresting. The best snapshot lens with excellent image quality is the Elmar-M and the Elmarit-M is a fine compromise between speed and size.
