Pentax Auto 110

This model represented the only complete ultraminiature SLR system manufactured for the 110 film format, although several fixed-lens 110 SLRs were sold.

To ensure that light travelling past the diaphragm blades could not get through to the film over time, the camera's mirror system also functions as a light-tight seal when in the viewing and focusing position.

In 2012/2013 ISO 100 film has been produced and marketed under the Lomography label, and gives excellent results, without the need to modify the cartridge casing.

The camera was offered in a special edition "Safari" model, identical to the Auto 110 except for the brown-and-tan color scheme.

Introduced in late 1982, the Super is nearly identical in basic shape and size to the previous model and accepts the same lenses.

The flash synchronization socket cover on the Super is permanently attached to the camera in an attempt to prevent loss, though many still get lost when the plastic tether breaks.

The 110 lenses have found a new life with the Pentax Q system, which will accept them with an adapter, albeit with a 5.6x crop factor (effective increase in focal length).

[2] The lenses can also be mounted on Panasonic/Olympus Micro Four Thirds cameras with an adapter, and the crop factor is only 2x, the same as on the original Pentax 110 body.

The 110 Winder II, introduced in 1982, adds a continuous shooting mode and improves the battery cover door, which was fragile on the original.

A custom electronic flash unit, the AF130P, was part of the original Auto 110 system, and was produced until the camera ceased being manufactured.
