I made a "half-joke" before, that I use a third-party camera body with my Nikkor lenses. For film- I moved from Nikon SLR's to Nikon Rangefinders about 20 years ago. I've used fixed-lens Rangefinder cameras since 1969 and SLR's since 1970, age 11 and 12 respectively. I have and use both RF's and SLR's, like seeing out-of-the-frame for RF's, simple/positive-lock manual focus, and seeing through the viewfinder the moment that the picture is taken. SLR's- ultra-wide angle, longer telephoto, and micro-Nikkors.
With Digital- Nikon DSLR's The Df is as close to a classic SLR that I'm used to. Nikon is not going to do a Digital RF- so onto Leica. Nikon made most of their RF lenses in S-Mount, Contax Mount, and Leica mount. I have most lenses in all three mounts.
This vacation, I took the Leica M9 and 4 Nikkor lenses and the Nikon Df and 4 Nikkor lenses.
Today, it was the M9's turn. Most of these are with the Nikkor-PC 8.5cm F2. This type lens is the one that got the attention of David Douglas Duncan and the following tour of the Nikon factory. This lens was made ~1955 or so, which is as old as the Gulfarium in Ft Walton Beach, Florida. I've been going there since a kid, starting about 50 years ago. It has been refurbished, expanded, and extended to a rescue and breeding program in the last two decades or so.

This lens has a long throw for the focus, it helps with moving subjects when you want to track where they will be. Not all were in focus, but more than half of shots like this worked out.
