After trying the D-LUX 5 at Photo Plus Expo 2010, I had the opportunity to shoot with two very legendary lenses in the Leica lineup. The 50mm F/0.95 Noctilux is the fastest lens available in the lineup and the 90mm F/2 has been touted as one of the sharpest lenses the manufacturer makes. See the samples below, all of which were shot wide open.
The intro photo for this story was shot with the Noctilux. All photos shot with the Leica M9 reviewed a while back.

For portraits, the 90mm is amazing. This is also one of the perfect portrait focal lengths.
