Image Quality & Optical Design

Ultra-Wide, Sharp, and Fast

Designed for APS-C sensors, the 15mm focal length offers a broad 83.6° angle of view, ideal for capturing immersive landscapes and interiors. The bright f/1.4 aperture enables excellent low-light performance and precise subject separation.

Advanced Optics

The optical construction features 13 elements in 11 groups, including FLD, SLD, and three aspherical elements. This combination suppresses chromatic aberrations, controls distortion, and maintains edge-to-edge sharpness while reducing size and weight.

Smooth Bokeh & Flare Control

A rounded 9-blade diaphragm ensures smooth out-of-focus highlights. The lens design and coatings minimise flare and reflections, maintaining contrast and clarity even in bright, high-contrast environments.

Autofocus & Video Performance

Stepping Motor AF

The stepping motor provides quiet, fast, and accurate autofocus, ideal for both stills and video. Focus breathing is well-controlled for smooth focus transitions when recording.

Design & Handling

Compact and Lightweight

Measuring 62.8 mm in length and weighing 240 g, this lens is extremely portable, making it ideal for handheld, gimbal, or vlogging applications. Dust- and splash-resistant seals enhance durability, and the coated front element resists water and oil.

Intuitive Controls

The customizable control ring allows quick adjustment of aperture, exposure compensation, and other functions. The included petal-shaped lens hood reduces flare and protects the front element from accidental bumps.
