An APS-C-only fast wide prime — the most-recommended budget lens in the Sony E creator community. Used on his A7 III in crop mode, which gives him roughly a 24mm-equivalent field of view.

An APS-C-only fast wide — she shoots it in crop mode on the A7 IV. The same lens Jeff Su uses for the same workflow, which is a strong signal that this is the de facto pick for E-mount talking-head.
