Image Quality & Optical Design

Ultra-Wide, Sharp, and Fast

The 15mm focal length offers an 86.9° angle of view, perfect for capturing expansive scenes. Its f/1.4 maximum aperture provides excellent low-light performance and creative control over depth of field.

Advanced Optics

The 13-element, 11-group optical layout combines FLD, SLD, and aspherical elements to suppress chromatic aberration, reduce distortion, and maintain edge-to-edge sharpness even at wide-open apertures.

Flare & Bokeh Control

The rounded 9-blade diaphragm produces smooth bokeh, while lens coatings and optical design minimise flare and reflections, ensuring clear, high-contrast images in challenging lighting.

Design & Handling

Portable and Durable

Measuring 64.8 mm in length and weighing 220 g, this lens is extremely compact and balanced. Dust- and splash-resistant construction and a coated front element enhance durability and ease of cleaning.

Intuitive Controls

The manual aperture ring offers direct control, with an 'A' position for camera-based aperture adjustments. The included petal-shaped lens hood reduces flare and protects the front element during active use.
