+24 pts“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.”

+37 pts“VERY weird choice with the a7s. The a7r is ancient and is not a good camera. The a7riii will give you better AF, better battery life, better ergo, better controlls etc.”
