Megadap ETZ21 Pro+ Mount Adapter I purchased this used a few months ago, but I am selling it because I am changing mounts. I had no particular problems while using it, and there were almost none, so I think the condition is good. The previous owner also hardly used it. I hope you will check the images carefully, but even so, there are some signs of use, small scratches, and scuffs. I cannot guarantee its use, so please understand. Thank you. - Brand: Megadap - Model Name: ETZ21 Pro+ Thank you for looking.
