Clear distance and depth of field scales on the barrel facilitate precise adjustments, while a smooth rotating, knurled ring offers seamless manual focus control. Further enhancing its durability, SP (Super Protect) coating on the front and rear lens elements repels dust, water, and grease, ensuring consistent performance even in challenging conditions.

The lens covers a practical focal length range of 30.5 to 61.5mm in the 35mm format, making it ideal for everyday photography needs. Its HD coating minimizes reflections and flare, enabling high-contrast, ghost-free images. The DC autofocus motor operates discreetly for quiet performance, while the weather-resistant construction with seven seals ensures reliability in various shooting environments. Additionally, the rounded nine-blade diaphragm produces beautiful bokeh effects, adding a touch of artistry to your shots.
