Why do I see squiggly lines in the viewfinder of my rangefinder?

This type of defect seen through the viewfinder is caused by oil leaking from the unit on to the lens. This is caused during the manufacturing process, and because it can show up months later it's hard to catch during our normal quality control process. If your unit is under warranty, we would be glad to get this replaced.

Please open a ticket with our customer support team to start the replacement process:
