FAQs:
What is a Summicron lens?
‘Summicron’ is a designated label Leica uses for lenses featuring an f2 maximum aperture. Summicron lenses come in various focal lengths, including 28 mm, 35 mm, 50 mm, 75 mm, and 90 mm. Leica originally assigned the term to their first M-system lenses. Later, Leica also used the term for R lenses and, finally, for the most recent SL lenses.
What does Leica ‘SL’ stand for?
Born from Leica’s fundamental idea to support the work of creatives with the highest level of optical quality, Leica designed SL lenses to deliver unsurpassed results for photographers and filmmakers. Users can expect edge-to-edge sharpness, accurate colour reproduction, and natural bokeh when purchasing an SL series lens. APO lenses in the SL series hold the highest standards, with apochromatic correction for exceptional results and a compact build for easy storage and transportation.
