Pentax 110 18mm f/2.8 Lens

The Pentax Auto 110 18mm f/2.8 is one of the smallest interchangeable wide-angle SLR lenses ever made, designed for Pentax's wonderfully quirky Auto 110 miniature SLR system. Despite being barely larger than a bottle cap, this little lens is a genuine piece of photographic engineering, offering a wide-angle perspective in a package that makes even pancake lenses look enormous.

Designed for the Pentax Auto 110 and Auto 110 Super cameras, the 18mm f/2.8 provides a field of view roughly equivalent to 36mm on a full-frame camera. That makes it a great option for street photography, travel, landscapes, and everyday snapshots on 110 film.

Like the other lenses in the Auto 110 system, the 18mm features a fixed f/2.8 aperture, with exposure controlled by the camera body's internal shutter and aperture mechanism. It's an unusual but clever system that helped Pentax create one of the most compact interchangeable-lens SLR systems ever produced.

These lenses have also developed a following among mirrorless photographers who enjoy adapting unusual vintage optics for creative projects, particularly on smaller-sensor cameras.

Condition: ONE-OFF

This lens is in one-off condition due to moderate internal haze. The haze is noticeable and may result in reduced contrast, increased flare, and some softness, particularly when photographing brightly lit or backlit subjects.

The lens remains usable, but buyers should expect some optical imperfections compared to a clean example. It could also make an interesting candidate for someone interested in experimenting with softer vintage rendering or attempting an optical cleaning.
