K&F CONCEPT KF-42E2 M42-E Lens Adapter
Product Details
This is a K&F Concept M42-E lens adapter.
I purchased it for my Sony mirrorless α7IV, but it was barely used and has been stored in a dry cabinet, making it in excellent condition.
I will ship promptly.
Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.
Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.
Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.
Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
