Congrats on your R4 and 50mm 'cron. I've got an R4 with a Vario Elmar 35-70mm and an M5 with a Summicron 35mm f/2. How do I feel about my Leicas? I'll refer to the Henri Bresson quote someone posted a few posts back and that's that. Nothing like Leica cameras. Even the compact digital ones are amazing, never mind the digital M's. But the camera is only as good as what you create with it through your own composition.....the camera's just a tool, but you might as well have the best tools for the job!
