Voigtlander 65mm f/2 Macro APO-Lanthar Aperture Series: Mosaic (Sony A7R IV)

Voigtlander 65mm f/2 Macro APO-Lanthar

If you want to see what the 60 megapixel sensor of the Sony A7R IV can deliver, this is a reference example that maybe cannot be beaten.

This series from f/2 through f/8 evaluates the Voigtlander 65mm f/2 Macro APO-Lanthar on an extremely demanding subject that makes mincemeat of most lenses, mercilessly revealing every weakness, lack of symmetry, etc. Most lenses require f/5.6 or f/8 to sharpen the whole mosaic.

Sony A7R IV 4-shot pixel shift was used to capture the best possible detail. Results with pixel shift will always look notably better than without (assuming no checkerboarding issues).

Flatness of field is of particular interest because at 60MP, small deviations across the field are not so small, and stopping down past f/4 begins to degrade micro contrast from diffraction.

Voigtlander 65mm f/2 Macro APO-Lanthar Aperture Series: Mosaic (Sony A7R IV)

Includes images up to full camera resolution of 60 megapixels.

The about $999 Voigtlander 65mm f/2 Macro APO-Lanthar surely is a must-have lens and a 'steal' for any Sony shooter for whom manual focus is acceptable. Meaning go buy one right now if you are serious about image quality on the Sony A7R IV.

This is the best lens so far that I have tested on the Sony A7R IV— few lenses approach it, let alone deliver what it does at f/4.
