Leica SL
Leica has launched a new series of high-performance prime lenses for its SL full-35mm mirrorless system, with the first two available now and another two schedule for launch in the latter half of 2018.
 
The new lenses available now are an APO-Summicron-SL 75mm f2.0 ASPH and an APO-Summicron-SL 90mm f2.0 ASPH.
 
Both have an all-glass optical construction which employs 11 elements (in nine groups), including one aspherical type to correct for distortion. All elements feature anomalous partial dispersion characteristics to minimise chromatic aberrations and optimise centre-to-corner sharpness. Both lenses employ an AF drive using ‘Dual Synchro Drive’ (DSD) stepping motors which enable the entire focusing range to be traversed in 250 milliseconds. The 75mm lens has a minimum focusing distance of 50 centimetres while the 90mm’s is 60 centimetres. In both cases, this enables a maximum magnification ratio of 1:5. Both models have a minimum aperture of f22 and a 67 millimetres diameter filter fitting.
 
On the way is a Summicron-SL 35mm f2.0 ASPH and an APO-Summicron-SL 50mm f2.0 ASPH. The APO-Summicron-SL 75mm f2.0 ASPH is priced at $6400 and the APO-Summicron-SL 90mm f2.0 ASPH at $7000.
