Japanese optical manufacturer Cosina has announced three new lenses at the CP+ show in Yokohama. The trio consists of two lenses for full frame Sony E-Mount cameras, and a new Nokton 50mm F1.2 lens that will come with a Leica M fitting.
COLOR-SKOPAR 21mm F3.5 Aspherical | Sony E-mount
The COLOR-SKOPAR 21mm F3.5 Aspherical is designed for Sony E-mount cameras and measures only 39.9mm in length. Its 10-bladed iris promises attractive out-of-focus highlights, while the closest focus will be 20cm (~7.9 inches). The optical design uses nine elements in eight groups, and Cosina claims the lens has excellent contrast and resolving power even when used wide open.
The lens will be manual focus, and will feature electronic contact with the camera.
MACRO APO-LANTHAR 110mm F2.5 | Sony E-mount
The other E-mount lens is the MACRO APO – LANTHAR 110mm F2.5, which will offer close-up shooters 1:1 reproduction from a closest focus point of 35cm (~13.8 inches). Cosina says it aims to eliminate chromatic aberration, and that it will use a floating focus group to ensure maximum sharpness at all focusing distances.
The optical design packs 14 elements in 12 groups into a 99.7mm long housing, and the iris will contain 10 blades. Again, focus is manual, but electronic contacts allow the lens to communicate with the camera.
NOKTON 50mm F1.2 Aspherical | Leica M
The lens for Leica M-mount cameras is a new standard NOKTON 50mm F1.2 Aspherical VM that will feature two double aspherical lenses and a coupled rangefinder focusing system.
Cosina claims the lenses performs very well wide open, and that it will produce attractive blur in out-of-focus areas. The 12-bladed iris will contribute to the out-of-focus effect, and the closest focusing distance of 70cm (~27.5 inches) will ensure users can make the most of it. The 4.9cm-long lens will use eight elements in six groups and will accept filters in the 52mm fitting.
This lens joins the existing 50mm F1.1 and F1.5 versions in the Voigtlander Nokton series.
Cosina has not said yet when these lenses will be available or how much they will cost when they arrive; however, the company did have working reference samples on display at the show that visitors could try on their own cameras, so it’s reasonable to expect that we won’t have to wait too long.
