Leica M lenses on Fujifilm X · harvested 2026-08-15
The M-Mount Catalogue
100 lenses. 6 manufacturers. No autofocus, no contacts, no grades, and no apologies for any of the three.
Harvested from the makers' own pages by the editorial desk.
Not scored by P. Lotor, who has never once held one of these.
True of every lens on this page
All 100 lenses below, mounted on a Fujifilm X body through an M adapter, behave the same way — and it is a property of the mount rather than of any particular lens. So it is stated here once instead of appearing as six columns containing the same six answers ninety-one times.
- Focus
- Manual only. No AF motor, no focus-by-wire, no electronic focus coupling.
- Aperture
- Manual, set by a ring on the lens. The body cannot change it.
- Electronic contacts
- None.
- EXIF
- The lens reports nothing. Focal length and aperture in EXIF come from the camera-side adapter setting, if one is configured, not from the lens.
- Stabilisation
- No lens in this catalogue contains optical stabilisation. Any stabilisation is the body's IBIS.
- Autofocus on X
- None. No adapter in the guide provides AF for M glass.
Adapter: FUJIFILM M MOUNT ADAPTER, graded S in the X-mount guide. Graded in fuji-x-guide.json under data.adapters_and_tubes. Third-party M-to-X adapters exist and are not enumerated here.
Why there is no grade column
Deliberately absent and deliberately null rather than omitted. Grades, usage scores and prices are the operator's editorial judgement; a harvester that generated them would be inventing the one part of this guide that is supposed to be a human opinion. The X-mount guide's own principles say grade_ignores_price and unknown_is_better_than_speculation, and those sentences either mean something here or they are decoration.
So the columns are absent rather than empty. 0 of 100 lenses carry a grade, 0 carry usage scores and 0 carry a price, and printing three columns of dashes would suggest a harvest that failed rather than an opinion that has not been formed. When someone forms it, the columns arrive with it.

Records flagged for review
A missing spec field means the maker did not publish it on the page that was read. It never means zero, "N/A", or "unknown but probably". Every lens below has been read off a page the maker publishes. That is a claim about where the numbers came from, not a claim that the numbers are complete.
The wide-angle question, answered once
Symmetrical wide-angle M designs put light on the sensor at a steep angle near the edges of the frame, which on digital sensors can produce edge smearing and colour shift that the same lens never showed on film. On APS-C the body crops to the centre of the image circle, so the steepest rays never reach the sensor and the effect is much less severe than on full frame. This is a property of the geometry, stated once. It is NOT applied to individual lenses. The per-lens `digital_sensor_note` field is reserved for a statement the MAKER makes about a specific lens; no extractor currently fills it, because none of the specification pages read so far carries such a statement, and the harvest will not write one from its own knowledge of how a given wide-angle behaves. It is null on every lens, and that null is the honest value rather than a placeholder: a real per-lens claim needs a real per-lens source, and adding one is editorial work with a citation, not a parse.
The equivalent focal lengths are computed, not published
Every “eq.” figure in the table is stated focal length x 1.5 — the 1.5× Fujifilm X APS-C bodies crop — and no maker on this page states it. An equivalent focal length describes framing only. It does not change the depth of field, the entrance pupil, or anything else the maker stated. 1 record publish no focal length at all, so no equivalent is computed for it.
Flagged for review — 19 records
Records that disagree with themselves, or whose numbers came out of marketing prose rather than a specification table. A lens is not flagged for being unusual: the 7Artisans 35mm publishes f/5.6 as both its widest and its smallest aperture because it has no aperture ring, and that is the truth about the lens rather than a defect in the record.

The Catalogue
Served in focal-length order, wide first. Every value is the maker's own published figure, with the row label it was read from kept underneath — hover any cell to see it. An em dash means the maker did not state it, and means nothing else.

How to read a cell
- ●
- maker states it 33 cells
- ○
- maker states it is ABSENT 1 cell
- —
- nobody has said either way 392 cells
The pair that matters is ○ against —. An asserted absence and an absence of assertion are different claims, and one row apart in the same column they must not share a glyph. Across these 100 records the maker writes the negative down exactly once — Cosina prints “N/A” in the rangefinder-coupling row of the 10mm Heliar-Hyper Wide. Everything else in that column that is not a range is silence, and is drawn as silence.
A printed value is a statement in its own right, so it needs no mark: hover it for the maker's exact wording and the table row it was read from. The marks are for the cases where there is no value to print. ⚑ next to a lens name is an internal inconsistency or weak provenance, listed above.
Specification columns are the manufacturer's own published figures, read from the pages listed under Source with the label recorded per field. Hover a value to see the row it came from. Angle of view is quoted on the format the maker quotes it on — full frame for almost all of these — and is not the angle you will get on an APS-C body.

Uneven by listing. Some 7artisans.store product pages carry a four-column specification table (focal length, aperture range, blades, mount compatibility, filter size, weight, angle of view, focusing range, optical structure, lens material); others carry none at all, with the numbers rendered inside marketing images. The corporate site 7artisans.com is Chinese-only with no English mirror and no working sitemap. Where fields are missing here they are genuinely unpublished, not merely unparsed.

Artra Lab sells its own designs from its own Shopify store, which also carries other makers’ used stock; only products whose Shopify vendor is Artra Lab were read. Nothing on the store states where the lenses are made.
Admitted 2026-11-01 (#57). One record per product listing: the 28mm f/2.8 Φ28 is three listings (brass, black paint, silver chrome) and the 50mm F1.2 Nocturne three limited editions, each with its own table, so each is its own row. The Custom Made Lunaelumen is sold as a Leica M variant but its own table names only Sony E, Nikon Z and Canon R, and it is flagged.
Every site above was read only where its own robots.txt permits it, at the harvester's default rate floor. The per-brand robots findings are recorded in the source file rather than summarised here, because a summary of a permission is not a permission.
Why this is a separate page
The X-mount list is a recommendation engine: graded, scored per use, filtered by budget. This is a reference catalogue of what M glass exists and how it behaves once adapted. Merging them would put a rangefinder lens with no contacts into a sports-lens ranking.
The X-mount ledger lives at The Glass.
