Key Take-Aways:

The SG-image MF 24mm f/6.3 is a manual-focus full-frame pancake lens with a single fixed f/6.3 aperture, a 76 degree diagonal field of view, a 0.25 m minimum focus distance and a 1:8.0 maximum magnification. SG-image lists a metal barrel and an approximate weight of 74 g, gives the size as 58 mm across by 16.7 mm long and sells it for $76 in the L-mount selection. The maker pitches the wide focal length and narrow fixed aperture at “set it and forget it” shooting with a massive depth of field. As of Oct 2026, one video and no written reviews are linked. isofss, a Japanese-language channel, sets it against the Color Skopar 35mm F3.5 pancake in a head-to-head, and its title, “Small is justice”, frames compactness as the lens’s appeal; there is not enough coverage linked here to say more about its image quality.

From SG-image:

This MF 24mm f/6.3 fixed aperture pancake lens is the ultimate tool for discreet, everyday shooting. With a razor-thin design that’s no bigger than a body cap, this lens transforms your full-frame camera into a truly pocketable and inconspicuous companion.

Its fixed f/6.3 aperture and manual focus allow for a simple, “set it and forget it” shooting style, providing a massive depth of field for capturing sharp, in-focus street scenes with ease.

SG-image publishes one set of figures for all mounts (E, X, Z, R and L), so the figures above are that single set. The maker gives the weight as “Approx. 74g” and the filter size as “37/49mm”; the frontmatter uses the first figure, 37 mm. The maker lists one aperture blade.
