I just converted my Leica 80mm Summilux to fit my Nikon D700 and this is what I have shot so far. This lens is incredible. It offers such a unique character foot print, that I love how all my images look. At 1.4 you can see how beautiful the depth of field is. And of course as you stop down it just gets super sharp. I know that Leica Lenses are super expensive but I feel that their performance warrants some consideration.
