I keep an SBOOI 50mm finder on my IIIa and use it constantly. Obviously, it's not needed on my M3. I also have a 35mm finder, but usually just guestimate the width.
I don't know if there is a single 180mm one, but I have this one - its a zoom that goes from 35mm to 200mm. One of the click stops is 180mm. Here is a pic.Jim Cain said:Ok, lets turn the question around to the longest length. Did anyone ever make an 180mm viewfinder that could be used on an M8 and an 135mm lens? I have tried this lens on the m8 with good results--in the center.
