The IIIg (1957) is the final screw-mount (LTM / M39) Leica. It refines the IIIf with a **larger viewfinder** showing **parallax-corrected projected frame lines** (50 mm and 90 mm) — the first time Leica brought the M3-style frame-line system to a Barnack body. Mechanical horizontal-cloth shutter to 1/1000s, no meter, no battery, no AE. Built simultaneously with the M3 (which made the M-bayonet Leica's future); the IIIg was kept in production as a lower-cost alternative for photographers who already owned LTM lens systems.

Released 1957 as the last Barnack body. Production ran three years and ended 1960 — total volume only 41,000 units, an order of magnitude lower than the IIIf (184,000) or M3 (226,000). The IIIg lost commercially because the M3 was simply better at every job; surviving sales went to LTM-system owners who didn't want to re-buy lenses for M-bayonet. After 1960, Leica's screw-mount system became collectible-only.
For LTM enthusiasts, the IIIg is the ultimate Barnack — the only screw-mount Leica with M3-style frame lines and the polish of late-Wetzlar build. Used prices reflect the rarity: a clean black IIIg approaches $3,500 in 2026; chrome bodies go for $1,800–2,500. It's also the most-functional screw-mount: the larger finder makes 50/90 lens use practical without external accessory finders.
For shooters who own an LTM 50mm Summicron, Summilux, or specialty Voigtländer lens, the IIIg is a meaningful upgrade over the IIIf. Otherwise, the M3 is the more rational purchase.
Leica Screw Mount lenses (any era). Same as IIIf but with a more usable finder. Can adapt to M-bayonet bodies via Leica official LTM-to-M adapters.
