I’d like to see them reduce the number of steps it takes to custom white balance. As of now, you’ve got to depress a fn button, scroll down through custom 2, custom 3 then set, depress, point at wb card, depress again, then choose where to save - as many as seven steps if you’ve saved your setting to C1 (fewer if you’ve saved to C3).
I’d also like to see Sony add tap to focus on the playmemories app, as well as zebras.
