Thypoch Simera 35mm f/1.4

Thypoch Simera 35mm f/1.4

The Simera 35mm f/1.4 was one of the two lenses that introduced Thypoch, a Chinese maker, to the Leica M community, arriving as a fast, fully manual rangefinder prime aimed at photographers who want a wide-aperture 35mm without Leica pricing [1][2]. Thypoch positioned it openly against Leica's own 35mm lenses, borrowing several Leica-style design cues while keeping its own identity and a much lower cost. The lens is notable among M shooters for a distinctive depth-of-field display that uses a row of dots filled with red to show the in-focus zone for the chosen aperture, a feature reviewers singled out as one of its most appealing touches.

Optically the lens uses 9 elements in 5 groups and a 14-blade diaphragm, which gives near-circular openings as the aperture is closed down. The barrel is built from aluminum alloy rather than the brass used on some Leica and later Thypoch lenses, yet it remains solid and relatively compact at roughly 50 mm long and 272 g, with a 49 mm filter thread. It focuses manually and is rangefinder coupled, with a textured, well-damped focus ring; the minimum focus distance is 0.45 m. The M-mount version carries an infinity lock catch on the focus mechanism, which reviewers found more of an annoyance than a help, noting that Thypoch dropped the lock in favor of a Leica-style focus tab on the lens versions made for mirrorless mounts. The lens is offered in black and silver finishes and is not six-bit coded, so it will not be automatically recognized by Leica M bodies.

The same optical design has been produced across multiple mounts, including Leica M, Sony E, Nikon Z, Canon RF and Fujifilm X, with the non-M versions using a different focus tab arrangement. Finish variants have also been described, including a non-brass "Typ I" matte black intended to match cameras such as the Leica M10 and M6, and a glossier black aimed at black-paint Leica bodies. Buyers should note that the lens is a recent production item rather than a vintage collectible, so condition concerns are typical of a new lens rather than the haze or coating problems found on older glass.

Optical qualities

Rendering Documented impressions describe a contrasty look that some reviewers compare loosely to the "Leica look," with pleasing subject isolation and smooth out-of-focus backgrounds at f/1.4. One reviewer felt that, online, images from the Simera would be hard to distinguish from those of a comparable Leica 35mm and that it could be mixed with Leica lenses without obvious mismatch. Coverage of this specific lens is still limited compared with long-established M lenses, so the notes below reflect early reviews rather than years of collector consensus.

Sharpness Center sharpness is reported as generally very good, with strong close-up detail, while the edges are somewhat soft wide open and improve noticeably on stopping down.

Contrast and color Color reproduction is described as accurate and the overall look as contrasty, with minimal distortion noted in testing.

Bokeh and transitions At f/1.4 the background blur and subject isolation were found pleasing, with soft out-of-focus areas, aided by the 14-blade diaphragm.

History

Development and Launch Thypoch entered the market with the Simera 28mm f/1.4 and Simera 35mm f/1.4 as its first products, both fast manual primes for Leica M. First-impression coverage of the M-mount pair appeared in early 2024, presenting Thypoch as a new manufacturer for the M system. The brand name is explained as a combination of "thy" and "epoch," with the Simera line name said to mean "today".

Production Evolution The Simera 35mm has been expanded from its original Leica M form to a range of mirrorless mounts, and the mirrorless versions adopt a focus tab in place of the M version's infinity lock. Differing barrel finishes have also been documented, including matte and glossier black options intended to complement specific Leica bodies.

Special editions No widely documented factory special editions of the Simera 35mm f/1.4 are noted in the available sources beyond the standard black and silver finishes and the various lens-mount versions.

Collector Notes Because the lens lacks six-bit coding, it will not be identified automatically by Leica M bodies, which is worth keeping in mind for users who rely on lens recognition for corrections or EXIF data. Prospective buyers should also confirm the mount version they are getting, since the M-mount model uses the infinity lock while the mirrorless versions use a focus tab. Accessories such as the matching hood, caps and 49 mm filters are worth verifying as present and correct when buying used.
