Thank you for viewing. Functionality was confirmed on a 7D. Currently, there is an aperture issue, and while autofocus works, the shutter does not fire. The shutter fires in manual focus. There may be other defects that I am unaware of. I will check to the best of my ability if you have any questions. The exterior has scratches. There is distortion around the front. There is some dust inside the lens. Includes the body and rear cap only. This is a junk item, so please consider the above condition and purchase it with the understanding that it is for repair or parts.
