Convenient handling

The lens' wide zoom ring ensures convenient handling. Putting the zoom ring in front allows the lens barrel to be more compact. The inner focusing system eliminates front lens rotation, enhancing the lens' stability and allowing use of Circular Polarizing filters.

Designed to minimize flare and ghosting

Flare and ghosting were thoroughly measured and monitored from an early stage in the lenses development to establish an optical design which is resistant to strong incidental light such as backlight. The Super Multi-Layer Coating reduces flare and ghosting and provides sharp and high contrast images even in backlit conditions.

Minimum focusing distance of 45cm

With a minimum focusing distance of 45cm and a maximum magnification ratio of 1:4.6, this lens is excellent for close-up photography.

Hyper Sonic Motor

The HSM (Hyper Sonic Motor) ensures a silent, high-speed AF function. Optimizing AF algorithm, smoother AF is achieved. It also enables full-time manual focusing capability which allows sensible focus adjustment by simply rotating the focus ring.

Incorporating Rounded diaphragm

The 9 blade rounded diaphragm creates an attractive round bokeh at large-aperture settings.

Design concept

The new product lines incorporate rubber for the attachment part of the provided lens hood. For better usability, the designs of the lens cap and AF/MF changeover switch have been improved. In order to ensure high accuracy of the product, all metallic parts and the new compound material, TSC (Thermally Stable Composite), which has a high affinity to metal parts, are housed internally. On the zoom ring, the last three digits of its release year are engraved so the lens can be identified according to the year of its launch.

Brass made bayonet mount

This lens incorporates a brass made bayonet mount which has both high accuracy and durability. A special treatment
