I saw O'Toole's comments about the Voigtlander 110 f/2.5 Apo Lanthar. That is the first negative report I've read about that particular lens. Here's a quick Chat GTP summary: "The Voigtlander 110mm f/2.5 APO-Lanthar is an outstanding, premium manual-focus macro lens for Sony E-mount, widely praised for its exceptional sharpness, apochromatic (APO) correction, and beautiful bokeh. It offers 1:1 magnification and produces excellent image quality with essentially zero chromatic aberration." If you google reviews on the lens, you'll see that it is highly regarded. I have used premium Rodagons, Componons, Nikkors, and many others. The Voigtlander is the best. I routinely use one on a Sony A7r IV for copying 35mm slides and negatives. It easily out resolves whatever I put in front of it in combo with the Sony.
