Thank you for viewing. Item for sale: Canon EXTENDER RF 1.4x I am selling this because I am changing my entire camera system. I purchased it used, but it is very clean with no scratches. There is no original box, but it comes with a dedicated pouch. Stored in a dehumidified storage. I used it with the RF100-500, and there was not much perceived degradation in image quality or AF speed. Returns are not accepted to prevent product substitution. I am also selling an R6 Mark II body and an RF100-500. I will offer a small discount if you purchase them together. - Brand: Canon - Model Name: EXTENDER RF 1.4x - Accessories: Dedicated pouch
