Canon Extender EF 2x III - Good Condition. By attaching this between your camera body and an EF lens, you can double the focal length while maintaining the high performance of your EF lens. I recently purchased this from Camera Kitamura last month as a used AB (Good Condition) with professional maintenance, but I am selling it because I found it difficult to use with a dark zoom lens, as the autofocus struggled and I couldn't get the shots I wanted. I have only used it for about 20-30 shots since purchasing it. Camera Kitamura rated it as AB (Good Condition), but in my opinion, it is in beautiful condition with no scratches or dirt. Items included: * 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 this is a used item. Thank you for your consideration.
