Light Lens Lab 28mm f/2 "Apochromatic"

What exists of this lens is a line on someone else’s list. On 11 August 2026 Leica Rumors reported that five apochromatic M-mount lenses were to follow the 35mm f/2 Apochromatic — 28mm, 50mm, 75mm, 90mm and 135mm, all at f/2 — coming, in its phrase, “in 2027 and beyond”. The 28mm is the widest of the five. No formula, no prototype, no price, no ship date and no confirmation from the maker have appeared since.

Light Lens Lab’s own announcement, published a week before that report on 4 August 2026, is narrower and worth reading against it. It sets out an aim to “independently develop high-performance optical designs”, calls the 35mm f/2 “the first lens created under this project”, and commits to exactly one named successor: a newly developed 50mm from 2027 with “its own new, independent optical design”, after which the research continues “in other focal lengths”, the 50mm “followed closely by other focal lengths”. A 28mm appears nowhere in it. The distinction is worth holding, because Leica Rumors rests its report on a previous post by the maker and this is that post: the promise of more lenses is the workshop’s, the list of which five is the rumour site’s. So the specification on this page is a rumour site’s account of a range the maker has said will continue, and the aperture and the focal length are the entire claim.

The distinction the announcement draws matters more than the focal length does. Almost everything Light Lens Lab has shipped exists because an older lens does, and the interesting question about each of those lenses is how much of the original survived the copy. The apochromatic series is defined against that: designs of its own, aimed at a correction standard rather than at a discontinued object. There is no vintage 28mm f/2 apochromatic rangefinder lens to recreate, so nothing in this catalog is the counterpart to this entry and none is linked as one.

There is a second reason to hold this page loosely, and it is specific to 28mm. This would be the workshop’s second attempt at a fast 28 for the M. The first, a 28mm f/2 ASPH announced in August 2023, was cancelled a year later; the maker said the design had proved impractical in physical size during testing, and shipped a 28mm f/2.8 instead. The obstacle then was mechanical rather than optical — a fast 28 that will not fit on a rangefinder body is not a rangefinder lens — and nothing in the 2026 announcement says what has changed. An apochromatic design carries more glass, not less. Until a barrel is shown, treat the f/2 in the name as an intention.
