50 mm battle: Sonnar vs Planar

This technical post is a comparison between two Zeiss ZM lenses: the Sonnar f/1.5 and the Planar f/2. For practical reasons the comparison is not done on film, but with a Sony A7. I compare jpg files.

Let’s start at f/2. Left Sonnar, right Planar

This is the full picture: the Planar has more vignetting.
