Chinese photo enthusiast Benny Wong mounted his large (and rare) Canon 50mm f/0.95 lens onto his tiny Olympus E-P1 Micro for a pretty awesome looking setup.

The Canon 50mm f/0.95 is known as the Canon “dream lens”, and there’s a Flickr group dedicated to it that contains plenty of sample photos. The lens occasionally pops up on eBay for $500+, and the adapter needed for using it with your MFT camera will also set you back an additional $100-$200.
