Publicly documented as reading the same way as the A7 III generation, but not yet added to our model-matching table — treat as not-yet-supported until we do.

Canon, Nikon, Sony and Fujifilm publish a rated shutter durability for most bodies — for the A7 IV (ILCE-7M4), that figure is approximately 150,000 actuations. This is a statistical durability rating from the manufacturer, not a hard limit — many shutters keep working well past it, and some fail earlier.
