Yep, once you catch on to its methods, it is at the least a camera that grows on you and develops its own very nice functions. But in my weaker moments, I'll admit- if that lens was mounted on a Fuji GW690 body, I'd snatch one up in a second. The lens is what makes it worth dealing with all the unique elements.
One of the nice things about the rangefinder setup is that there are no mirrors. All prisms. Well, they did silver the back side of a couple of prisms for a while but then gave that up. Any problems in the silver lead to ghost areas but no real damage in use. The later Chevron simplified this, but the Chevron sis add a small overlapping image section along the center split. This gives both matching lines and superimposing images for focusing.
Once you catch on to how it works, it has its own well-done logic. One of the problems is that since the mechanics are so sui generis, not many people work on them. Not because they are difficult but because you need to throw out what you know about other cameras and deal with its own logic.
