I have just got a Sony A7III for my new astrophotography hobby, and main interest at the moment is shooting the Milky Way. Later my interest will move towards the more DSO type stuff with longer lenses on an equatorial mount, but for now using a tripod and wide angle lens is what I want to do.
Really in between these two lenses: the Sony FE 24mm f1.4 GM and the Sony FE 20mm f1.8 G.
Anyone have any experience of either one?
I have also heard focussing to infinity is tricky with these. Has that been your experience? As a beginner, this needs to be something I can do quite easily, so if it is hard on these lenses I may need to think about the Zeiss Batis 18mm f2.8 as a backup choice.
