My Batis 25mm finally arrived two days ago. This completes phase one of gear acquisition. A7ii, Sony 70-200 f/4, Sony Zeiss 55 f/1.8, Voigtlander Heliar 40 f/2.8, Zeiss 25 f/2.0 I have never been a wide angle guy before, so I am challenging myself with the 25mm. On my Leica M8.2, my two favorite focal lengths were 50mm and 25mm. So I am only challenging myself by the crop factor (1.3) of the M8.2. I am still learning and experimenting but am extremely pleased so far. The most difficult thing for me has been learning the many tricks of autofocus.
