A photo I made of an Old Fashioned cocktail looking through a fancy Leica 50mm f/1.0 Noctilux-M lens owned by my buddy Dave Krugman. Dave's grandfather passed this lens to his father, and now he has this rare and beautiful piece of glass.
Check out https://instagram.com/GrandArmyBar/ now for a portrait looking throw this glass (this time a by photographer Jose Silva). The lens on its own is amazing but you can also do tricks like this with it... Which is what nerdy photographers do for fun when we're together.
