Medium format

Last week I went out with a group of photographers shooting medium format. I was kindly lent a Mamyia RZ and fell in love with it. It was my first experience with medium format cameras and looking into that 3d viewfinder was fascinating. Of course, it's not as easy as it seems, the focus and depth of field are not exactly what you see in the viewfinder, but still, with a bit of practice...

Now that I think of it, what is this fascination I have with bicycles lately? I don't even know how to ride one.
