In retrospect the seals on the back aren't THAT bad but they are starting to disintegrate which means I will need to replace them at some point.

I can't believe how cheap the lenses are though, I can build a holy trinity for nothing. How does the 180 look on 6x7 is it close to 100 or 85? Haven't decided on a wide I want the 50 but I hear it distorts pretty bad
