All of the lenses feature a classic all-metal body with two of the new lenses being from the fast-aperture Nokton series, including an 40mm f/1.2. The latter is the fastest full-frame 40mm ever produced, according to Cosina. It features a minimum focusing distance of 16 inches and is designed to provide edge-to-edge sharpness. Of particular interest to video shooters, the aperture ring can be switched into a silent, step-less mode that allows smooth iris changes without an audible clicking noise, according to DPReview.
The 35mm f/1.4 is patterned after the classic M-mount version, but uses an updated optical formula redesigned for Sony digital sensors. Interestingly, it is built to include aberrations when shot wide open in order to produce a more charactered bokeh. Stopped down, the sharpness will naturally increase.
Finally, Cosina showed off the final version of the APO-Macro Lanthar 60mm f/2 that it originally announced at Photokina last September. With a minimum focus distance of 12.2 inches, this lens features a reproduction ratio of 1:2 to detailed close-ups. That’s not the strongest magnification ratio out there, but the bright f/2 aperture is a unique feature not often found on similar macro lenses.
While all three of the above lenses were on display at CP+, Cosina has not yet released information on when they will be available to the public — or how much they will cost. Not all Sony users will look to put such an “old school” lens on their high-tech digital cameras, but those after a classic shooting experience definitely have something to look forward to.
