That’s great. With the price drop of the A7 IV the A7 III on the used market will also go down, which means I can finally afford the A7 II.

So basically Open Gate recording? "On the other hand, 4K 60fps full-frame is amazing, but currently locked behind high-end models like the A7S III and FX3, with price tags starting above $3,000." ZV-E1.
