I was wondering why the cosina lenses I found at VV (value village) on the ’wall of shame’ (bags of stuff, priced) had such value, on line. then I looked closer. bubbles. likened to Leica. (waiter! take this old stuff away! bring me some fresh wine!)
Then the explanation to people that it’s not about the bubbles themselves.. but how they formed, why they formed. Boutique, or pinnacles.. can be like that.....
