I post (hopefully) high quality videos from most of the concerts I attend! When I can get it in, I prefer to use my Panasonic GX85 camera body with an Olympus 45mm or 75 mm f.1.8 lens attached. If that isn't allowed, I use my Sony RX100 vii - a tiny point and shoot with very nice quality. On the very rare occasions the Sony is not allowed, I will use my iPhone 13 pro.
