Probably not a review for the lens in question

This review of the Sigma XQ 500mm f/8 is probably not for that mid-70s era, fixed narrow aperture mirror lens. (The review mentions AF, DG, and f/4.5.)

Nice catch. As the user is no longer a member, and there was no clear indication of the lens reviewed, I have deleted the review.
