Omnar W-Nikkor-C 3.5cm f/1.8 LTM Satin Black Custom Build

Omnar W-Nikkor-C 3.5cm f/1.8 LTM Satin Black Custom Build

This is a small, fast wide-angle for rangefinder cameras: a 35mm lens with an f/1.8 maximum aperture, finished in satin black and built as a custom limited offering. The name pays tribute to the original Nikon W-Nikkor-C 3.5cm f/1.8, a fast 35mm optic from the rangefinder era, while the build itself is a contemporary product dated to 2025.

Optically the lens uses a compact seven-element, five-group arrangement and a nine-blade diaphragm, which gives a near-circular aperture as the lens is stopped down. It is physically very small for its speed, measuring 26.5 mm long and 50.5 mm in diameter, weighing 200 g, and accepting 43 mm filters. The barrel is fitted with an LTM (Leica screw, M39) mount and is rangefinder coupled, so it focuses through the camera's coupled rangefinder down to a minimum focus distance of 0.9 m. It is not six-bit coded, as expected for a screw-mount lens, and can be used on M-mount bodies with an LTM-to-M adapter.

Documented public information specific to this particular satin-black custom build is limited. As a small-run modern interpretation of a vintage formula, individual examples may vary in finish and detail, so prospective buyers should confirm the exact configuration with the seller rather than relying on a single reference example.

Optical qualities

Rendering Detailed, independently published rendering tests for this specific satin-black custom build are limited. Based on its design parameters, it is a fast 35mm lens with a seven-element, five-group layout and a nine-blade diaphragm, the latter favoring rounded out-of-focus highlights when stopped down slightly. Because it is a compact, high-speed wide-angle, the widest aperture can be expected to trade some edge performance and to show the gentle, lower-contrast character typical of classic fast 35mm rangefinder designs, but precise claims about sharpness, contrast, flare, distortion, or vignetting are not made here in the absence of confirmed test data.

History

Development and Launch The lens takes its name and optical inspiration from the Nikon W-Nikkor-C 3.5cm f/1.8, a fast wide-angle from the Nikon rangefinder period. This custom build is a modern product dated to 2025 and supplied in LTM (M39) mount with a satin-black finish.

Collector Notes As a custom, limited build rather than a mass-produced catalogue lens, key points to verify before purchase are the exact finish, the mount and rangefinder-coupling accuracy on the intended body, and the included accessories such as caps and a suitable 43 mm filter or hood. Examples should be checked for coupling alignment and clean glass. Where documented production details are sparse, confirm specifics directly with the maker or seller rather than assuming uniformity across units.
