The Leica 28mm f/2 ASPH APO-Summicron-SL is a versatile wide-angle prime for those with extreme detail and resolution in mind. Key features include:
Highly corrected optical design
Dual Syncro Drive autofocus system
Durable, weather-sealed construction
L-mount lens
Highly Corrected Optical Design. The Leica 28mm f/2 ASPH APO-Summicron-SL has a ten-group/thirteen-element optical design. There are six aspherical elements correcting distortion and spherical aberrations to the highest degree. The apochromatic design corrects for chromatic aberrations while the new multilayer coatings suppress surface reflections, flare, and ghosting, creating images with higher degrees of contrast and acuity.
Fast Autofocus. Leica’s Summicron-SL lenses use their Dual Syncro Drive autofocus system. Like the name implies, this system uses two small stepping motors that allow going from minimum focus distance to infinity in fractions of a second.
Solid Construction. All of the complex internals are wrapped up in a rugged, weather-sealed chassis. The AquaDura coatings found on this lens’s exposed elements and seals mean you can rest easy if you get caught out in harsh conditions.
L-Mount Alliance. As with all L-mount lenses, the Leica 28mm f/2 ASPH APO-Summicron-SL can be used on a number of cameras from its native Leica cameras to Panasonic’s S1 and S1R.
