Thank you for viewing. This is a set of the MFT-MOUNT AF TUBE 10mm and 16mm macro extension tubes from Commlite, compatible with Micro Four Thirds mount. There are some minor scratches and dirt, but the overall condition is good. Operation has been confirmed. Note: Since these are macro extension tubes, infinity focus is not possible. The price reflects a discount, so negotiation on price is not possible. Thank you for your understanding.
