Lens Description

The Pentax Q 01 Standard Prime is a normal prime designed for cameras with a Q (4.6X) sensor. This bright prime has a 8.5mm focal-length. It provides the same field of view as a 39.1mm lens on a Full-Frame camera.

This prime can focus down to 20cm from the imaging plane which gives it a maximum magnification of 0.05X. The lens supports autofocus and features a switch to disengage AF for focusing manually. While this lens is capable of AF, it does not have a built-in focus motor. It can only focus with a compatible camera body which features a mechanical AF-coupling.

This lens is only available for Pentax Q. Follow this link for all current compatible digital cameras: Pentax Q mount cameras.
