The Sigma 20mm f/1.4 DG HSM Art Lens features a fixed focal length and an ultra wide angle that allows you to capture landscapes, group photographs or wide spread spaces in single frame. Designed for APS-C DSLRs the 30mm (35mm equivalent) focal length makes the perspective more dramatic with the versatility to create exciting visual compositions.
The fast f/1.4 maximum aperture delivers stunning low light performance. The Sigma 20mm Art lens is equipped with a 9 blade rounded diaphragm that delivers a beautifully rendered bokeh which helps your subject stand out against the blurred background.
The auto-focus of the Sigma 20mm f/1.4 is driven by the HSM (Hyper Sonic Motor) which is both quick and quiet. The high speed focusing performance enables you to capture fleeting moments keeping your subject sharply focused. The HSM is also great for video shooting, allowing you minimising unwanted noise pickup generated by the operation of the lens when recording using the camera's internal microphone. Manual focus is also available, allowing you to fine-tune your focal point when shooting extremely shallow depth of field images.
The Lens construction incorporates 2 FLD elements, 5 SLD elements and 2 aspherical elements that minimize the chromatic aberration, coma and field curvature to deliver sharp, distortion free images throughout entire focusing range. The multi-layer coat applied to the lens elements reduces the reflection, flare and ghosting to ensure maximum clarity across all lighting conditions.
The built-in petal shaped hood guards the front element and protects your images from unwanted flare caused by harsh sunlight directly hitting the lens. This adds contrast to the image, ensuring the colours and details remain true-to-life.
The Sigma 20mm f/1.4 Art lens features an updateable firmware for future-proof performance and camera compatibility. Compatible with the Sigma USB Dock (sold separately) the lens can also be calibrated for focus fine-tuning and other parameters to deliver maximum imaging performance.
