What is the performance of Leica M3(5.0) camera? Help explain the parameter ratio. You see, I just started taking pictures. Sincerely! thank you

There is no magnification of 5.0, is there? The viewfinder of Leica M3 should be 0.9 1. This is the longest in Leica M, so it can also get better framing accuracy, and the viewfinder design is also very convenient to use. However, M3 is a bit old, so there are few Leica M3s that have not been overhauled and maintained in the market. There is no problem if it is handled by the original factory, but the disassembly, repair and maintenance of the camera without the original factory will cause invisible damage, which may affect the assembly accuracy. Leica's second-hand water on the plane is very deep, so it is recommended to be cautious. If you want to buy it, try to consider a machine that is relatively old.
