Preposterously large and rare Nikon 6mm f/2.8 lens for sale in London posted over on The Verge. All I can say is “hello lovely…”.
Seriously though, that’s huge. And remember that’s a 6mm in 35mm format, so it’s a “real” 6mm, not 6mm x 1.5x. I have no idea what you’d even use that thing for, other than an exercise in frustration not shooting your own feet (or in this case, your feet, legs, and waist).
