Since I have enjoyed the Retina's so much I picked up another Kodak rangefinder with the original intent of adapting its lens to my XP2.
Camera was in to nice of a shape to do that though so I cleaned the shutter and rangefinder and calibrated the meter and rangefinder. It is an interesting and very conflicted camera. Some parts are a great design but then it has a 'but' that goes along with it. It is a bakelite beast, but it actually feels very solid in hand.
No take up reel, film is pushed (not pulled) into an area for it to self roll. Double stroke winder which is a linear motion.
The rangefinder uses a large prism (no half mirror) and has 1:1 magnification. The main viewfinder has a gel color filter in it so that the rangefinder spot is very high contrast. Not as bright as a Konica IIIa but the patch is higher contrast and easier to see.
But the viewfinder position is in the way of trying to shoot with both eyes open using either eye in the rangefinder. Camera is in the way trying to shoot right eyed, your hand (on shutter release) is in the way shooting left eye. Shooting upside down you can use both eyes, if you can handle the inverted controls.
Camera has interchangeable lenses (35,50,90) and the rangefinder works for all of them.
But you need an auxiliary viewfinder to frame the 35 or 90.
It has a built in uncoupled meter but it uses the EV system so you need to turn a marker on the lens to the actual on body shutter speed and then adjust aperture to get the same EV number on the lens.
Full manual control is available but aperture is marked on the bottom of the lens so you have to flip it over to read it. While you are there you can also look at the film counter which is under the lens.
Haven't put a roll through it yet. I have the 35 and 50 and they are said to be very good lenses.
