Chase Reynolds did a pretty extensive lens comparison between 13 lenses for his Sony a7RII, a7SII, a6300 and out of all the lenses tested the Sony FE 55mm f/1.8 and the Zeiss Loxia 50mm f/2 Planar rose to the top for Chase. My personal favorites for an autofocus lens and manual focus lens are the Sony Planar T* FE 50mm f/1.4 ZA and Leica 50mm f/1.4 Summilux-M ASPH, but everyone has their own preference. There are so many great lenses today. Be sure to check out The Ultimate 50mm Lens Comparison at Lens Rentals and pick your favorites.
