thanks very much, Jorge! Leica is a long story. I got my first Leica, the M9 in 2009 with a defect sensor, got another sensor change last year and will sell it soon. I love the M Monochrom, it simply is a beauty! The puristic design of the camera is the best I know, the files are great to work with. And I like the Leica lenses. but I use the Sony A7R almost 100% since I got it. This is a universal camera for my needs and wishes. I use any lens on it like Nikon, Canon, Leica M, Leica R and enlarging lenses. Focus for the OTUS or the Zeiss 100/2 for example is easy and perfect. Let's see, what we will get soon this year :-) more than 400 portraits are in my flickr album: https://www.flickr.com/photos/dierktopp/sets/72157627967118544/
