You probably forgot that once Epson made a digital M-mount camera named R-D1. Mattias Burling tested it:
This is the Epson RD1, the first digital range finder with a Leica-m mount. It was released back in 2004 but still cost a pretty penny on the used market. I decided to review it after you, my viewers, decided I should via one of my polls here on youtube.
Also Casey tested the Epson:
This is by far the most interesting camera I have ever used. Its a digital camera from 2004 that STILL costs around $900 used. Is it worth the price in 2018? I think so.
