The 7Artisans 9mm f/5.6 ASPH was just announced and it can be ordered now on Amazon.
7Artisans announced the launch of the 9mmF5.6 full-frame prime ultra-wide-angle lens, which is the brand’s full-frame ultra-wide-angle camera lens following the launch of the previous 12mmF2.8 II APS-C.
Features of the 7ARTISANS 9mm F5.6 ultra-wide-angle lens:
This is a non-fisheye ultra-wide-angle lens designed and developed specifically for mirrorless full-frame cameras, suitable for Sony E, Nikon Z, Canon RF and L mount.
This lens has a field of view of 132 degrees, making it one of the few ultra-wide-angle lenses on the market. The manual focus lens features 16 elements organized across a dozen groups, including two aspherical and two ED elements.
The lens has a five-bladed aperture diaphragm that goes from f/5.6 to f/22 and promises 10-pointed Sun stars. The lens features separate dedicated control rings for aperture and focus and can focus as close as 7.9 inches (20 centimeters) .
The lens weighs 1.02 pounds (463 grams), and the lens dimensions are Φ55*length 78mm. Not a terrible weight for walking around with when you’re out shooting.
