7Artisans has been making lenses since 2015 and, like most of its back catalog, this is a fully manual lens with no built-in electronics. The lack of autofocus isn’t really a problem because, as a fisheye lens, the depth of field is gigantic.
The only real issue is that no lens-based EXIF data is recorded in images. I love the huge viewing angle and funky-looking distortion of fisheye lenses, this one being a ‘diagonal’ rather than ‘circular’ fisheye, so it delivers a frame-filling image on the full-frame cameras for which it’s designed.
