A scarce LTM rangefinder-coupled collaboration, the Lomography x Zenit Mercury 35mm f/2 is a Soviet-flavored standard wide that close-focuses to 0.45m.</parameter> <parameter name="long_description">## Lomography x Zenit Mercury 35mm f/2 Few modern rangefinder lenses are as poorly documented as the Lomography x Zenit Mercury 35mm f/2, a product of the partnership between Lomography and the Russian optics maker Zenit (KMZ). Collectors who have handled it report finding it through eBay rather than mainstream retail, with little published technical information and no widely circulated optical diagram, which has given it a reputation as an obscure, mysterious Russian lens [1]. The name ring is engraved "Mercury2," and at least one reviewer has linked the name to the Soviet-era Mercury half-frame cameras, speculating that the lens nods to that earlier line rather than copying its optics directly. Mechanically it is a compact LTM (M39 / Leica thread mount) lens with rangefinder coupling, so it can be used on Leica screw-mount bodies and, via an adapter, on M-mount cameras. The optical formula uses seven elements in four groups with a nine-blade aperture, and it focuses unusually close for a coupled rangefinder optic, down to 0.45m, which is well beyond the typical 0.7m to 1m minimum of vintage 35mm rangefinder lenses. The user who reviewed it noted achieving roughly 0.4m focus after servicing and described a close-focusing rangefinder lens of this type as remarkable, since coupled rangefinder optics that focus that near are uncommon. Reliable production details are limited. The lens is part of the broader run of Lomography x Zenit collaborations that also includes the New Petzval and the Lomogon, but the Mercury 35mm f/2 received far less promotion than those products. No factory variants, finish options, or special editions are widely documented; collectors should treat finish and engraving details as unverified until checked against the individual example in hand. --- ## Optical qualities **Rendering** Documentation is thin and rests largely on a single hands-on user account, so the following should be read as collector impression rather than tested performance. That reviewer described overall imaging as slightly low in contrast, comparing the look to the Jupiter 3+, with a saturated, distinctly Soviet color character on film. The center was reported as very sharp, even reaching strong edge-to-edge sharpness when stopped down to about f/5.6, while the extreme corners showed weak rendering with a hazy, soft quality and pronounced coma wide open. The same account found close-up performance notably better than distant subjects and suggested the high central resolution against degraded corners helps isolate a subject. The lens was also judged to weaken in high-contrast lighting. These are the observations of one user and have not been corroborated by formal testing. --- ## History **Development and Launch** The lens emerged from Lomography's collaborations with Zenit (Krasnogorski Zavod, KMZ), the Russian manufacturer behind the firms' jointly produced art lenses. It appears to date from around 2016 and was sold with minimal marketing, which is why so little reference material exists for it compared with the better-known New Petzval and Lomogon lenses. **Special editions** No major factory special variants, regional names, or alternative finishes are widely documented for this lens. **Collector Notes** Buyers should be cautious about mechanical condition. The one detailed account of the lens reports that the example arrived unable to reach infinity focus and required adjustment by a specialist repairer before it was usable, after which it focused down to roughly 0.4m. Given the scarcity of the lens and its limited paper trail, confirming infinity focus, rangefinder coupling accuracy, and the absence of internal haze is advisable before purchase. The "Mercury2" engraving on the name ring is a useful identification point. --- ## Sources * [1] Chan'Blog (chan.nds.hk). *Lomography Zenit 35mm f2 神秘俄鏡*. https://chan.nds.hk/blog/?p=9915
