Thank you for viewing! The Nikon AF-S TELECONVERTER TC-20E III is an aspherical teleconverter with a 2x magnification. I purchased it new, but I am selling it because it was not compatible with the lens I had. There is no box, but it has been stored in a dehumidified storage, so the condition is good. - Model: AF-S TELECONVERTER TC-20E III - Magnification: 2x - Features: Aspherical - Mount Type: F-mount There are no smokers or pets in my family.
