I bought the older Voigtlander 15mm recently and it came with the viewfinder but I don't need it as I'm using it on an M8. It's VERY bright and clear, minor signs of wear when examined under a work light but overall in very good condition. A joy to use but I just can't visualize the 21mm equivalent FL. Would probably work great for an 18mm lens as well. Asking $75 and also open to trades for some entry-level medium format gear. Will ship worldwide.
