There is only a hand full of lenses which incorporate an apodization element which improves bokeh at the cost of light transmission. Today I will compare two of them. The Sony STF 2.8/135 was released 1999 by Minolta and is known for it’s uniquely smooth bokeh. The Laowa STF 2/105 is a new lens released this year by Chinese newcomer Venus Optics. In this post I will see where their strengths and weaknesses lie.
The Zeiss Batis 18mm 2.8 is the latest addition to Zeiss’ line up of modern autofocus lenses and also the widest AF prime lens to date for Sony E-Mount. As many people (include me here) are now engaged in landscape astrophotography I am especially interested how the new Batis fares in this regard.

The Voigtländer 15mm 4.5 Super Wide Heliar E aspherical III is the first native E-Mount lens by Voigtlander. As there are three adapted Voigtlander lenses in my basic A7s-kit – see my reviews – I simply had to try this one out!

The Zeiss Loxia 35mm 2.0 Biogon is one of Zeiss’ manual focus lenses specifially designed for E-mount cameras. The modern design, the aperture “de-click” feature and the transfer of Exif-data sets it apart from adapted lenses. Read on to learn how it fares optically. Update: conlusion updated (06/05/2016)
