While searching for the best affordable film RF I learned something about the system design, namely the effective base length, RF construction and leaf shutter top speed. I find that pro grade RF such as the Leica has a long base length that the viewfinder is far away from the lens, beside to allow more precise focusing it also reduce blocking of view due to the lens, I don't see that much on vintage RF such as the very best Konica IIIA, the Minolta V2, Hi Matic, Petri 35....etc., but on the Yashica electro 35.
Similar to SLR, on low end RF the rangefinder is made of glass and mirror, on high end ones such as the Konica IIIA it's made of solid glass, so will not have mirror oxidation problem over time and produce clearer brighter image. On the other hand not all RF has automatic parallax correction built in that the viewfinder will shift when focusing, the rest simply provide a 2nd frameline for close distance. Regarding the shutter speed, most of the vintage RF can go up to 1/500sec that suited most needs, except the Minolta V2/V3 can go up to 1/3000sec but seems not necessary.
I am looking for a reliable and affordable vintage RF I guess I will go for the Konica IIIA, it has everything I want except a long base length, since it's a fixed lens camera I don't need high precision focusing. I wouldn't go for the Yashica mainly because it's electronic, I don't trust electronic camera that old, once it failed it will be total lost, that's why I don't consider the Pentax K2 and LX, it must be a fully mechanical one, so my choice is very limited.
