Though the A7 IV has major buttons and dials sealed, and sealing is provided throughout the body to minimize entry of dust and moisture (and therefore can be considered somewhat weather resistant), it does not sport an industry rating nor is it rated as freeze-proof. In fact, Sony is careful to post a disclaimer that the “Alpha 7 IV has improved dust and moisture resistance to provide outstanding reliability even in challenging outdoor shooting environments. Not guaranteed to be 100% dust and moisture proof.”
Of course, the Sony A7 IV is supported by a system of high quality lenses, vertical grip, external flashes, microphones, monitor hood, shooting grip with wireless remote commander, grip extension, and software that further expand the shooting system.
