Review on Laowa 100mm f/2.8 2:1 Ultra Macro APO Lens for Nikon F: Unleash Sharpness and Precision in Macro Photography by Patrick Goodrich

I love this lens. I knew it was manual focus when ordering, but I wasn't aware that this version has a manual iris. I agree, I just don't like how easy it is to push it to a different setting. This is my only complaint. I experimented with the aperture settings very quickly and found that F4 or 8 worked best. Full aperture is not the best setting for sharpness, but it is more than satisfactory.
