I know there's nothing really similar about them, but I can't help but be reminded of the D2/LC1 whenever I see RD-1 photos. Similar beautiful tonality and color, but with better DR on the RD-1.
Fortunately, I keep a little stone with "it's the photographer, not the camera" engraved on it, and rub it each time I go to this thread. So far it has saved me a lot of money...
