- For full-frame cameras
- Moisture Resistant Construction
- High precision AF
- Vibration Compensation
- Fluorine Coating
The AX (Anti-reflection eXpand) coating, especially effective for wide-angle lenses that tend to let in harmful light from peripheral areas, was developed to control rays that affect image quality.
High-speed, high-precision AF
Brilliant AF speed and precision is delivered by equipping the lens with a Dual MPU (Micro-Processing Unit) system and employing an enhanced AF control algorithm to improve performance. The AF drive uses USD (Ultrasonic Silent Drive), enabling high torque, high response, and silent operation. Additionally, theres a full-time manual focus override system so manual focus adjustments can be made at any time.
The newly developed VC mechanism reaches 4.5 stops, making it possible to shoot sharp photos over a wide range of photographic scenes, including indoor and outdoor shots as well as handheld shots at stopped-down aperture settings for landscape photography.
The front surface of the lens element is coated with a Fluorine Coating based on a newly developed fluorine compound with high water and oil-repellent properties. Therefore, the lens surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, dust, moisture, and fingerprints, thus enabling your lenses to be continually protected long-term.
Seals are located at the lens mount area and other critical locations to prevent infiltration of moisture. This feature provides an additional layer of protection when shooting outdoors under adverse weather conditions.
Rear filter holder
The SP 15-30mm has a filter holder as a standard feature that lets you insert various sheet filters into the rear side of the lens. This makes photography using filters much easier as it overcomes the problem of the curvature of the front lens elements that made shooting with filters difficult.
