Leica has just expanded its lineup of full-frame mirrorless lenses with the official release of the APO-Summicron-SL 75mm f/2 ASPH. and the APO-Summicron-SL 90mm f/2 ASPH. These two telephoto apochromats are designed specifically for the SL camera and are optimized for ultimate image quality. Also, the German-built lenses offer fast autofocus and durable construction to make them suitable for professional use. The two lenses share many features, including a fast f/2 aperture for shallow depth of field, but differ notably when it comes to the focal length. Leica is billing the 75mm as a more versatile option that will work in street, portraiture, and many other situations that will benefit from a slightly longer than normal look. It also has a minimum focus distance of 1.6'. The 90mm, on the other hand, is ideal for portraiture with its more compressed telephoto look that many portrait photographers crave, and a minimum focus distance of just under 2'.
The two lenses share a long list of features that make these some of the best lenses available today. These features include a Dual Syncro Drive Precision Autofocus system that provides fast and accurate movements, one aspherical element and anomalous partial dispersion for crisp, clear imagery across the frame, and a floating element to ensure optimal performance at any focusing distance. Professional lenses aren't just their image quality, since the ability to perform in less-than-ideal weather is critical for working photographers. The lenses are made in Germany to precise specifications with various seals to prevent intrusion of dust and moisture, while an AquaDura coating protects the front element. Additionally, the lenses come with a lens hood, caps, and bag.
