There’s a new super-fast prime lens for mirrorless shooters. The Handevision Ibelux 40mm f/0.85 (yeah, you read that right – f/0.85) is the product of a partnership between Chinese manufacturer Shanghai Transvision and German optical design firm, IB/E Optics. The press release calls the Ibelux 40mm f/0.85, “the fastest lens in the world.” There are faster specialized custom lenses but the Ibelux 40mm is nearly a full stop faster than Leica’s revered f/1.0 Noctilux, making it the fastest “serial production” lens available.

Look at the sample images from the below link


There IS a cheap alternative that will get you these specs.

There's a decent "zhonghi" or similar focal 0.72x focal reducer available. Use it with a 50-55mm F1.2 lens like a Nikon or Pentax 50/55mm F1.2 for ~$350


BTW, I've been noticing the prices rising steadily on F1.2 lenses, and availability is declining. KEH's supply of 50/55mm F1.2 Nikon's has dried up. FD lenses are still good, but changing the mount to EF may be necessary (look up edmika).

Been quite pleased with my Canon 55mm F1.2 SSC FD lens on the focal reducer. Assuming you've paid $400 (which is plenty), and it's $100 for the adapter, you're only looking at $500 for an equivalent lens.
