dim brightlines in Leica finder
I just got a 135mm Leica finder (SHOOC) and the brightlines are not what I was expecting. They are close to invisible in most situations, other times I can see part of the frameline. They are *darker* than the surroundings. A couple questions:
1)Most brightline finders (or Leica or this one in particular) the brightlines are easy to see, right?
2)How do they work? Is this correct:
Light enters the front, reflects off a mirrored surface on the side close to my eye, and is reflected back off brightlines on the surface farthest from my eye, creating lines brighter than the surroundings.
3)assuming that's right, could the front element be in backwards right now? How would I take it apart and fix it?
I bought this from KEH and returning it is an option, but I wanted to use it tuesday; so if I might fix it by taking it apart, I'd love to try that even at the risk of ending up with just parts. Thanks for any help and I'm going to keep searching for any resources...
