The Nikons I have are FG, F100, N60, D200. I have used an F2 (among others), and am still looking for one at a reasonable price. Don't get me wrong, I love my nikons and they surely do have some excellent glass out there! Part of my decision to go for the R leica is the glass can also be used on my Nikons. I happen to enjoy the compact size of the R4, and even though the design was originally partnered with Minolta, Leica still did quite a bit their own way. It is not just a Minolta body.
The R 90 Elmarit is the lens I have been looking at getting. Fortunately, my local lab/studio owner is a Leica fan and has the R lenses from 21 to 180 and a 70-200 zoom, she said I can try them out and see which one I would want to buy next.
Anyways, I am really enjoying using this camera!
