Camera · ILCE-7M4 · Dec 2021
Sony's fourth-generation full-frame hybrid body, and the model that established 33 megapixels and 10-bit video as the baseline for a mid-range camera.

The A7 IV replaced the enormously popular A7 III and moved the series decisively toward video, adding 10-bit recording, a fully articulating screen and the BIONZ XR processor.
Its mixed card slots are the detail that matters most for long-term ownership: one slot accepts both CFexpress Type A and SD, the other SD only, which shapes how owners configure backup recording and which cards they end up buying.
