The lens is officially called the Kipon Handevision IBELUX 40mm f/0.85 Mark 2. Kipon unveiled the original Handevision IBELUX 40mm f/0.85 lens back in 2013, and it was a collaboration between Kipon owner Shanghai Transvision and the German company IB/E Optics.
That lens and this latest Mark 2 version are the fastest production lenses available in the world of photography.
“The focusing on this is a bit of a pain in the ass at f/0.85,” Wong says. “You kinda expect that, really. When you’re looking through the viewfinder or LCD screen, the peaking may be flashing, but it doesn’t necessarily mean the bit you want in focus is actually in focus.
“When we’re talking about f/0.85, that plane of focus, the stuff that’s actually in focus, is incredibly shallow. It’s wafer thin.”
And when shooting wide open, the lens is “soft like baby poo,” Wong says. And there’s a “crap ton” of color fringing, but the bokeh has a nice quality to it.
“It’s not going to be a lens for everyday use, but a 40mm f/0.85 was never going to fulfill that role anyway,” Wong concludes. “It’s probably not going to be for everyone, but if you’re going to spend $2K on a big rose bokeh machine, all credit to you.”
