My new Oberwerk binoculars have stiff focusers. They were stiff right out of the box and get stiffer out in the cold. Keven from Oberwerk sent me a focuser from a damaged unit to test with. It got stiffer out in the cold but mine is a bit more so. Is this normal? And has anyone found a way to loosen them or do they loosen with use? This appears to be stiff by design.
