Sony tech - How to use the A7SIII with an APS-C / Super 35mm lens?
During training with the Sony A7SIII a common question I get is: since you can't use Super 35 mode in 4k video, can you still use APS-C lenses to film with? It's logical that you can't use Super 35 mode (= APS-C sized video mode) in 4k since the A7SIII films 4.2k in full sensor readout. Hence you can only use the Super 35 mode in FHD (1080p). In Sony full frame mirrorless cameras you can always switch between using the camera full frame or in APS-C. For photo you always sacrifice megapixels. The A9/A9II/A7II/A7III's 24MP becomes 10MP in APS-C, A7RIII's 42MP becomes a usuable 18MP in APS-C, A7RIV's 61MP becomes a very decent 26MP in APS-C. The advantage for photo is that you can turn a 600mm lens into a 900mm lens without teleconvertor.
