This compact lens is ideal for subjects such as landscape photography, architecture, astrophotography, and travel. It features a crop format RF-S design and is extremely lightweight at just 213g. A bright f/2.0 aperture and great corner-to-corner sharpness are paired with reliable autofocus performance that is both quiet and precise.

Samyang AF 12mm f/2.0 RF-S Lens for Canon RF Mount in More Detail
High Sharpness and Resolution
The Samyang AF 12mm f/2.0 RF-S lens delivers good levels of sharpness across the frame, making it a great choice for photographers who want high image quality at an accessible price. Its optical construction includes three Extra Low Dispersion (ED) elements and two aspherical elements to reduce the effects of chromatic aberration, distortion, and sagittal coma. This optical formula makes it well-suited for capturing astro and nightscapes in particular.
Bright f/2 Aperture for Creative Versatility
With a bright f/2 aperture, this lens excels in low-light situations, enabling clear images with a lower ISO even when light is limited. A shallow depth of field can isolate your subject when shooting very close, with a minimum focusing distance of just 0.2m allowing you to capture dynamic compositions. Additionally, a seven-blade aperture creates pleasing background blur and produces a distinctive starburst effect for creative possibilities when capturing point light sources.
Fast, Quiet Autofocus Performance
Samyang’s Linear STM (Stepping Motor) ensures that this lens delivers smooth, and accurate autofocus. Its near-silent operation makes it ideal for both photography and video, so you can capture moments with greater precision without disturbing your surroundings.
Compact Design with Great Features
Weighing just 213g and measuring 57.2mm in length, the AF 12mm f/2.0 RF-S lens for RF mount is designed for portability, ideally suited to outdoor photography and travel. The lens is compatible with tripods and gimbals, offering flexibility for both stills and video. Its sleek matte finish, accented by a red ring, complements your Canon camera design.
The inclusion of an AF/MF switch adds excellent manual override control, while robust weather sealing protects against light rain, snow, and dust covering the majority of outdoor shooting conditions. At 62mm the compact filter thread is a bonus for adding cost-effective lens filters, with options spanning astro filters such as the Urth 62mm Neutral Night Lens Filter Plus+ and the Hoya 62mm Starscape Filter, to a simple 62mm Circular Polarising (CPL) Lens Filter.
