Sony a7S vs. Leica M Typ240 infinity test with 21 Leica, Zeiss, Voigtlander rangefinder lenses

The Sony a7S is the third camera in Sony’s a7 series and this write-up is the third installment in my series testing various rangefinder lenses on this platform to determine technical performance when photographing a distant, near infinity scene. While this may seem a simple task, the combination of a rangefinder lens with a short exit pupil distance and a scene at infinity is the most technically demanding combination of variables influencing technical image quality from these ‘mirrorless’ cameras. Please refer to the original a7 shootout for an explanation why infinity focus is such a ‘torture test’ for these cameras.

The previous two installments of this series can be found here for the a7 and here for the a7R.

As a bonus comparison, I photographed the same scene on the same day, with the same lenses, using the Leica M Typ240 camera.

As with the previous a7 tests, I’m making this information and the high resolution files freely available for personal, non-commercial use only.
