The g series was the last of the screw-mount Leicas and was introduced after the M3 with bayonet mount. An improved view-finder with bright-line frames for 50 mm and 90 mm lenses was incorporated. Shutter speed calibrations were changed to be in geometric progression which made it easier to transfer meter readings. The height of the camera was increased slightly compared to the f series. The knurling on the film advance knob differs between early and later models.

This is a late model of the 13.5 Hektor with non-rotating focusing mount and E39 filter mount.

Visoflex I
This was introduced in 1951 and replaced the Mirror Reflex Housing PLOOT it was discontinued in 1962. Available in both screw and bayonet fittings.

This was a simple device providing a focusing screen which could quickly be replaced by the camera. Different accessories could be mounted on the front of the device such as bellows, extension tubes and focusing mounts. The common arrangement was to use extension tubes, a helical focusing mount for the lens and an aperture setting device to fit onto the front of the lens. Magnifiers could be attached to the focusing screen, these were the same as used on the rotating stage and Visoflex I.

The device was developed by Leitz New York. The first Wetzlar model (OOZAB) appeared in 1938 and was re-introduced following the war. The camera was clamped in position by a spring mounted bar, on early versions the bar had a single flat plate to rest against the camera later the familiar H shaped device was used. The standard Leica lens thread was used on the front of the device. This version could be used in conjunction with the Bellows I.

In 1957/58 a second version was introduced by Wetzlar this was of improved construction with rounded edges, the accessory thread was changed to 51 mm. The device was available for screw mount cameras (OOBAZ) and bayonet mount (OOTGU).
