Leica Noctilux-M 50mm f/0.95 Asph

If you can afford this and get your hands on, Grab it! This lens is the King of Kings! I could not get this lens for a year, and still very happy with Noctilux f1.0 (3rd gen). The bokeh was factastic and stop down, you get sharp photos as good as any Summilux/Summicron. However, I kept looking for 0.95. I placed orders in two stores, both telling me the wait time could be more than a year! When I found ebay listing at the same price, I did not hesitate a second before placing an order(well, I checked the seller's history and feedback to just to make sure.). Anyway, the 0.95, although quite heavier, beats 1.0 in sharpness, focus turns, and looks (So beaitiful on my M9), with different but preferable bokeh. Only problems with this King are the price and availability. This lens works great with Sony Nex, and Canon cameras, too, with proper adapters. This is the lens for very special occasions. The Object pops up while the background is smeared with silky painting. For daytime uses, you probably need at least an 8x ND Filter. For nightime, well, this lens makes it daytime.Read full review

Stunning images! Nothing compares. The most beautiful shallow depth of field and bokeh. The images the Noctilux produce just have that something special to them. No lens can do what it does!

It is more of a want than a need. This lens exceeds expectations, it is simply the best you can get.
