SHOOTOUT: Two Samples of Sony FE 24-70mm f/2.8 GM II vs Voigtlander FE 65mm f/2 APO-Lanthar: Deck and Roof
This page scrutinizes performance of two brand-new samples of the Sony FE 24-70mm f/2.8 GM II, using the Cosina Voigtlander FE 65mm f/2 APO-Lanthar as a reference lens, an exceptionally competent one.
Sample variation is often an issue with sophisticated lens designs, but rarely if ever have I seen such a severe case of bad lens assembly, and the resulting bizarre behavior on the right side.
