1,000th lens review: Sigma 1,000mm f/8 APO Autofocus (1992)

1,000 camera lens reviews! I'm think I'm starting to get the hang of this testing business, now. Full disclosure - it's not 1,000 DIFFERENT lenses yet, as I've re-tested old lenses occasionally or tested the same lens on multiple systems. And some of those 1,000 lenses are currently on Patreon early access. Still, please enjoy this review of a very rare optic: the first 1,000mm AF lens made.

All pictures taken by me on a Nikon Z7 camera.
