Meyer Optik unveils Nocturnus III 50mm F0.95 with new mechanics and Leica M mount

03 Apr

German lens manufacturer Meyer Optik Gorlitz has redesigned its super-fast 50mm F0.95 lens both inside and out, and has added a Leica M mount option to the existing Fuji X and Sony E Mount fittings.

The Nocturnus lll has a new mechanical construction, according to the company, that makes manual focusing and adjusting the aperture almost silent. This new version is somewhat lighter than the Mark ll model, and there is also a slight design change to the outer barrel of the lens that now sees a cut-away in the metal to show the aperture value in use.

The manual focus lens features a 15-bladed iris that closes down from F0.95 to F11, and the stepless aperture construction and ‘nearly silent’ focus control make it suitable for use in video. Inside you’ll find 10 lens elements in 7 groups, which gives the Nocturnus III a close-focus distance of 0.50m and total weight of 790g.

The new version of the lens is due to ship in August this year, and will cost $ 3,000 in either black or silver. Pre-orders made before the middle of April, however, can be made at a discount of up to 60%. For more information, visit the Meyer Optik Gorlitz website.

Press Release

Meyer-Optik-Görlitz launches new Nocturnus III 50 F0.95 with mounts for Sony-E, Fuji-X and Leica M

The third edition of the Meyer-Optik-Görlitz Nocturnus 50mm F0.95, which is known for its exceptional light intensity comes in a new design and features now mounts for Sony-E, Fuji and Leica M. The lens is currently available through a pre-sale campaign on the manufacture’s website.

Meyer-Optik has just announced the launch of the Nocturnus 50 F0.95. The super-fast manual-focus lens is optimized for use with full-frame sensors, but also works with APS-C cameras. The third edition comes in a new design and now features mounts for Sony-E, Fuji-X and Leica M. Within the next 14 days, the lens in offered in a pre-order sale, where it is available for less than 60% of its future MSRP.

Like its predecessor, the new Nocturnus comes with a focal length of 50mm and an aperture range from F0.95 to F11. Thus, the lens features a lot of versatility both when shooting in available light conditions and in terms of depth-of-field. Its 15 aperture blades with anti-reflective coating, make the new Nocturnus III 50 F0.95 a unique tool to create a pleasant bokeh with circular highlights whilst creating great sharpness in the focused areas.

The Nocturnus has a minimum focus distance of 50cm and weighs 790 grams. The new mechanical design of the Nocturnus III makes the Nocturnus also an interesting option for videography: Manual focus control and the stepless aperture ring operate almost silently.
