Old DSLRs from Canon, Nikon and Sony can be repurposed as webcams
Several older DSLR and mirrorless cameras, including Canon's EOS 6D and Rebel T6, Nikon's D5300 and D750, and Sony's A5100, A7 II and RX100 IV, remain on manufacturer compatibility lists for webcam use. Setup typically involves installing the maker's webcam utility, connecting via USB, switching to video or remote mode, and selecting the camera within apps like Zoom, Teams or Google Meet.
