Leica 35mm Optical Viewfinder SBLOO 12010. This is an optical viewfinder that attaches to the cold shoe. It's essential for using 35mm wide-angle lenses that the Leica M3 doesn't support. When you look through it, there's a bright frame, and you frame your shot according to that. It's a 35mm viewfinder with a universal mount, so you can enjoy stylish and practical customization by attaching it to something like a FUJIFILM X100VI. The frame is clear, and there are no issues with framing, but there is some clouding in the inner lens. Please check the photos for the scratches on the exterior. *Evaluation is subjective.
