LK Samyang is making another attempt at selling autofocus lenses for Canon’s RF mount. It announced that it’s bringing the Samyang AF 12mm F2, a 19mm equivalent ultra-wide prime for APS-C cameras, to the system and says that users should “stay tuned for more exciting releases in the RF-S family.”
The lens is weather-sealed, and the company says it’s meant for outdoor photography, such as landscapes, architecture, and astrophotography. The lens’ optical formula is made up of 12 elements in 10 groups, with three ED elements and two aspherical lenses. It has a 7-bladed aperture.
It weighs 213g (7.5oz) and is 5.7 cm (2.25″) long. It accepts 62mm filters and has a minimum focusing distance of 20cm (7.9″).
The company previously attempted to make autofocus lenses for RF mount, but pulled them off the market shortly after they went on sale. Viltrox, another third-party company, has said that Canon threatened legal action against it for making lenses for the system.
Other companies, such as Sigma and Tamron, have recently started producing APS-C lenses for RF, though they’ve explicitly stated that they’ve done so under license from Canon. Samyang’s 12mm F2 product page doesn’t appear to mention anything about an official collaboration with the company.
The AF 12mm F2 will cost $449, though it’s currently listed as a pre-order on Samyang’s site. That’s slightly less than the retail price for the lens on Fujifilm’s X mount, though slightly more than it costs on Sony’s E-mount.
