Canon Extender EF 2x III - Good Condition. By attaching this between a camera body and an EF lens, you can double the focal length while maintaining the high performance of the EF lens. I purchased this from Camera no Kitamura last month, used AB (Good Condition) with professional maintenance, but I am selling it because I found it difficult to achieve the desired results due to significant autofocus issues when used with a dark zoom lens. I have only taken about 20-30 shots with it since purchasing. Camera no Kitamura's rating was AB (Good Condition), but in my opinion, it is a beautiful item with no scratches or dirt. Items for sale: ・Extender body ・Front cap ・Rear cap Everything in the images is included. It has been used very little and is in beautiful condition, but please understand that it is a used item and consider purchasing it. Thank you.
