7artisans 75mm f/1.25 II

The 75mm f/1.25 II is 7artisans' second take on its ultra-fast short telephoto for Leica M mount, positioned as an affordable counterpart to the Leica Noctilux-M 75mm f/1.25 ASPH. At a list price of around 469 USD, reviewers have repeatedly framed it as a budget route to extreme subject separation, noting that the closest Leica analogue costs many times more [1][2]. The Mark II is a thorough revision rather than a cosmetic refresh: it pairs a new optical formula aimed at higher wide-open sharpness and lower chromatic aberration with a noticeably lighter body, reduced from roughly 600 g on the original to 514 g [2].

The lens uses a seven-element design in six groups, with the manufacturer specifying one extra-low-dispersion (ED) element and one high-refractive (HR) element to control color fringing and improve consistency at full aperture [1]. It is built largely of metal, with an aperture ring carrying engraved markings, luminous indicators, and a depth-of-field scale, and a focus ring that turns to a minimum focusing distance of 0.8 m [1]. The 12-blade diaphragm is intended to keep the aperture opening round for smoother out-of-focus rendering. The lens is not rangefinder coupled, so focusing relies on live view, an electronic viewfinder, or focus aids rather than the M body's rangefinder patch; one field test stressed that the review sample arrived uncalibrated and required adjustment before it focused accurately, and that focus peaking and magnified manual focus were effectively necessary for consistent results wide open [2]. It accepts 62 mm filters and is offered in black.

This is the second M-mount version of the lens, succeeding the earlier 7artisans 75mm f/1.25, which used a Sonnar-derived seven-element formula, weighed about 600 g, and was widely sold under the "Photoelectric" branding with a 0.7 m minimum focus and a higher blade count cited in some listings [3][4]. Buyers should be careful not to confuse the two generations, as both share the same focal length and aperture but differ in optical design, weight, and minimum focus distance.

Optical qualities

Rendering Documented impressions of the Mark II describe sharp, contrasty images with good color and a three-dimensional look once the lens is correctly calibrated, with a smooth transition into the out-of-focus areas that lends portraits a painterly quality [2]. The manufacturer markets the lens for soft, creamy bokeh and strong subject isolation at f/1.25 [1].

Sharpness A field test reported some softness at the widest aperture, which the reviewer considered expected for a lens this fast, with images becoming sharp and contrasty when stopped down slightly; performance was judged broadly comparable to a Nikkor 50mm f/1.2 AI-S and clearly better than an older Voigtländer Nokton 50mm f/1.1 [2].

Digital use Because the lens is not rangefinder coupled and has a razor-thin focus plane wide open, reviewers found focus peaking and magnified manual focus on mirrorless bodies, or careful micro-adjustment on a digital M, close to mandatory for reliably sharp results [2].

Collector and user notes The most consistent practical caveat is calibration: at least one reviewer found the lens unusable until adjusted and noted that 7artisans supplies calibration tools with it, so this is treated as part of setup rather than a defect [2].

History

Development and Launch 7artisans introduced the original 75mm f/1.25 as what it billed as the world's smallest f/1.25 portrait lens, built around a Sonnar-type optical formula and sold for use on Leica M rangefinders and, via adapters, on mirrorless cameras [3][4]. The Mark II followed as an updated design, with hands-on coverage of the new version appearing in early 2026 [2]. Its stated purpose is to deliver Noctilux-class shallow depth of field at a fraction of the cost of Leica's own 75mm f/1.25 [2].

Production Evolution Relative to the first version, the Mark II adopts a revised optical formula incorporating ED and HR elements, cuts weight from about 600 g to 514 g, and updates the aperture ring with refined damping, clearer markings, and luminous indicators [1][2]. The earlier model was commonly listed with a 0.7 m minimum focus distance, whereas the verified figure for the Mark II is 0.8 m [3].

Collector Notes The main point of confusion is between the two generations of 7artisans 75mm f/1.25, which look similar and share specifications on paper but differ in optical design, weight, and close-focus capability; checking for the "II" designation and the lighter body helps confirm which version is in hand. Prospective buyers should expect to calibrate a new sample and verify that the supplied calibration tools and caps are present [1][2]. Some retailer listings for the lens line cite differing blade counts and figures across versions, so specification details should be confirmed against the specific generation being purchased rather than assumed from a single listing [3][4].
