A light and compact lens with a big zoom.
This is a 500 mm mirror reflex manual focus lens. It covers the 24x36mm full-frame format. It comes with a T-mount, so a T-mount to K-mount adapter is required in order to mount the lens on a Pentax K-mount camera.
The lens aperture is a fixed F6.3, it has no aperture control. It can be used in Av and M exposure modes.
The not focus parts gives a donut bookeh.
