Description — Lensbaby 50mm Canon RF Mount
The Lensbaby Obscura 50 is a 50mm, full-frame special effect prime lens built for mirrorless camera systems. Offered in Canon EF, Nikon F, and Sony E mounts, it delivers broad compatibility across popular mirrorless platforms. At just 70g, this lens is remarkably lightweight, making it a practical addition to any creative kit without adding meaningful bulk.
Focus is entirely manual, with no autofocus and no image stabilization, keeping the shooting experience deliberate and hands-on. The lens carries a maximum aperture of f/32, suited to the special effect character of the optic rather than light-gathering performance. With its standard focal length range classification and prime construction, the Obscura 50 occupies a unique niche for photographers drawn to experimental, fine-art, or abstract image-making.
No filter thread is specified in the product data. This is a lens for creative photographers who want results that diverge meaningfully from the clean, sharp rendering of conventional optics.
