The Leica IIIg, the final model of the Barnack Leica series. The Leitz product code is GOOEF. The serial number is in the 840,000 range, produced in 1956. The IIIg is generally regarded as having been introduced in 1957, meaning this example was manufactured in the year prior to its official release, just like the earliest IIIg batches. As with early Leica M3 bodies, the serial number engraved inside the body of the IIIg matches that on the top cover.
The IIIg appeared three years after the debut of the Leica M3 in 1954. True to products from Leitz’s golden era, no expense was spared in its design and manufacture, and its outstanding quality is captivating even when simply admired. Technologies from the M3 were incorporated, including bright-line frames for 50mm and 90mm lenses with parallax correction. The viewfinder is excellent, and in terms of usability, this is arguably the most refined and user-friendly Barnack Leica ever made.

There is a crack in the vulcanite covering on the right side of the rear panel, and depending on the viewing angle, traces of repair can be seen. Aside from this, only light rub marks are visible around the logo area on the top cover and on the bottom plate, and overall the camera retains a very clean appearance.
The crack in the vulcanite has been carefully repaired, so it can be used with confidence. The distinctive tactile feel, with its pronounced original grain, is something unique to original vulcanite of the period.
Fully overhauled in December 2025. Film advance, shutter, and all other operations are extremely smooth, and the viewfinder is clear and bright.
A clean, well-sorted Leica IIIg well suited for practical use.
