Each lens is checked for previously undetectable high-frequency details using 46-megapixel Foveon direct image sensors.

HSM (Hyper Sonic Motor)

HSM (Hyper Sonic Motor) delivers high AF speed and extremely quiet performance and the enhanced algorithm offers even smoother automatic focusing.

Minimum focusing distance

This lens offers a minimum focusing distance of just 40 cm, a maximum magnification ratio of 1:5.6, and superb image quality at every shooting distance.

Rounded diaphragm

High-precision, rugged brass bayonet mount

Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.
