Funleader Artizlab Classic 35mm f/1.4

Funleader Artizlab Classic 35mm f/1.4

Released in 2025, the Artizlab Classic 35mm f/1.4 is a compact M-mount fast wide-angle whose external design openly references Leica's 1960s Summilux-M 35mm f/1.4 version 2, the filter-thread-less variant often paired with the 12504 hood [1][2]. Artizlab, described as a project founded by Leica collectors and photography enthusiasts working in collaboration with Funleader, set out to pair that vintage look with a modern optical formula at a price far below the lenses that inspired it. Reviewers consistently frame it as a character lens rather than a clinical performer, and a homage rather than a copy[3].

Optically the lens uses a modern multi-coated design that is not the same as the single-coated original it resembles, and contemporary reviews describe it as eight elements in six groups with a ten-blade aperture stopping down to f/16. It is notably small for an f/1.4 35mm, with a barrel built from aluminium and copper rather than the brass favoured by some Leica users, while still feeling tight and free of flex. The focusing tab carries an infinity lock, a feature that divides opinion, and the close gap between the hood mount and the aperture ring can make aperture changes awkward until handling becomes familiar. Minimum focus is one metre, in line with the period Leica design, and the lens is supplied with a 12504-inspired vented push-on hood and a drop-in Serie VII style UV filter rather than a threaded front.

The lens has appeared in both a black finish and a silver finish, and a revised version was released that is described as optically identical to the first run with minor tweaks, reportedly addressing reports of a tight fit on some Leica M film bodies and an infinity stop that was slightly off. Sellers have indicated that current stock is the revised version even when not explicitly marked, which is a useful point for buyers trying to identify which run they are handling.

Optical qualities

Rendering Documented impressions describe a lens with deliberate vintage character rather than corrected, high-contrast modern output. It is reported to be a little soft wide open while still holding usable detail, sharpening up noticeably by f/2 with around f/2.8 cited as a practical sweet spot for street use. Bokeh is generally regarded as pleasant and surprising for the price, and high-contrast subjects shot wide open can show a glow and some colour fringing that is largely correctable in post. Compared with the Voigtlander Nokton 35mm f/1.4, one reviewer found the Voigtlander more predictable and slightly sharper with cleaner flare and less coma, positioning the Artizlab as the more creative, lower-cost option.

History

Development and Launch The lens became available in early 2025 and was promoted as a way to obtain the look and feel of the 1960s Summilux-M 35mm f/1.4 v2 at a small fraction of that lens's value, with early hands-on coverage appearing first from Asian reviewers. Artizlab presented it as their first M-mount lens, designed in collaboration with Funleader and aimed at photographers wanting a classic-style fast 35mm in a crowded field that ranges from budget TTArtisan options up to Light Lens Lab and Voigtlander.

Production Evolution A revised release followed the initial run. It is reported to be optically unchanged but to include small refinements, with the maker said to have corrected a tight fit experienced on some Leica M film cameras and adjusted the infinity stop, and to offer the lens in silver alongside the original black.

Collector Notes Several reviews stress that, despite the strong visual resemblance, the optical design differs from the original Leica Summilux-M 35mm f/1.4 v2, so buyers should treat it as an homage and not expect identical drawing. The original Leica it imitates is single-coated while the Artizlab is multi-coated, an internal distinction worth keeping in mind when comparing rendering. Because current stock may be the revised version even when unlabelled, verifying the finish, the fit on a given body, and the presence of the supplied vented hood and drop-in Serie VII style filter is sensible before purchase. One detail to note as a discrepancy: contemporary reviews state the lens ships rangefinder calibrated, whereas this entry records no rangefinder coupling; buyers should confirm focusing behaviour on their own body.
