Sony FE 35mm f/1.8 Aperture Series: Mosaic (Sony A7R IV)
This series from f/1.8 through f/8 evaluates the diminutive Sony FE 35mm f/1.8 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 FE 35mm f/1.8 Aperture Series: Mosaic (Sony A7R IV)
Includes images from f/1.8 to f/8 at up to full camera resolution.
I had no idea that there were thirteen (13!) 35mm full-frame lens choices for Sony, not counting zoom options!
