I thought you might enjoy a couple of photos of one of my favorite shooting rigs ... Leica M10 Monochrom with Pentax-L 43mm f/1.9 Special and 43/50 Viewfinder https://flic.kr/p/2smLxYy https://flic.kr/p/2smEMR8 This is such an excellent lens, its SLR equivalent (Pentax-L 43 Limited) my favorite from the years I used Pentax equipment. I've had the lens for a few years now ... they were made in a small batch of about 2000 and sold mostly in Japan. I found this example without a finder at a good price, which didn't matter when I was using it on EVF cameras, but since I'm using the Leica M (digital and film) most of the time now, I've been hunting for the original finder made for it. I finally located one at a fair price; it arrived yesterday... it's beautifully finished and optically excellent. An M, the Pentax 43, and the new Voigtländer APO-Skopar 75mm f/2.8 are a compelling, 'do most of what I ever want in a very small package' travel kit ... Leica M10 Monochrom Travel Kit w 43 and 75mm lenses https://flic.kr/p/2smLxYJ The 75mm is a stunning performer too, and it's actually a little smaller/lighter than the Pentax 43. Also note that I find the use of a green filter on a monochrome digital sensor does "just the right thing" about 95% of the time, so I include one for each lens as a part of the travel kit. Now to go out and do some shooting again. :D enjoy, G — "No matter where you go, there you are."
