Ellie ★★★★★

The electronic contacts on the A-series mount paired perfectly with my film body, making metering a breeze for such a compact lens. Shot a whole roll of street scenes at f/2 and the soft fall-off had that classic vintage character I was after.

Claire R. ★★★★★

The aperture ring on this lens clicks into each f-stop with a satisfying tactile precision that my newer lenses lack. For the price, the sharpness in the center of the frame is genuinely impressive, making it a steal for anyone with a compatible body.

Abigail F. ★★★★★

Shot a roll with it on my old K1000 and the manual focus ring feels buttery smooth. For a vintage lens the glass is surprisingly clean, and those electronic contacts work perfectly with my camera.
