Almost forgot - When I first bought the M8 I was interested in using it for black-and-white because I saw many images online from the M8 that were converted to black-and-white and I was impressed with the look. I thought using some older lenses would be very good for this purpose as well so I found a 50mm Summarit and then the 85mm Summarex. They are great for black-and-white as I hoped but I am also really struck with how rich the colors are from the older designs. This really surprised me, I wasn't expecting it.
