The Elgato Cam Link is worth checking out if you're serious about this - it's an HDMI video capture device which presents itself on the computer end as a UVC compatible USB webcam and will accept the HDMI streams DSLRs usually send. They're expensive though.
There are other similar devices on the market too but not sure how good they are for this situation.
- atonse 6y agoThey're all bought out by price gougers. I've been trying to get one for two months but won't pay $400 for one.
- localhost 6y agoIf you’re using a PC, I bought the PCIe version of the camlink from Best Buy a few weeks ago without any problems (they even have it in stock).
- tomatocracy 6y agoEven before that they weren't cheap though. The RRP for the camlink 4k is USD129 I think - more expensive than a typical 1080p webcam.
- atonse 6y ago$129 is fine with me. The quality you get out of a DSLR is really good. I’ve entered that phase in my cycle where I’d rather buy separate pieces that are good quality and put them together.
- kbouck 6y agoElgato sells other capture cards (eg. HD60), which still seem available. I recently bought a raspberry pi hi quality camera (and lens) to tinker with, and was able to connect it to my mac via pi->hdmi->capture-card to make a nice webcam view with the bokeh effect. the total cost of this example does add up, but still cheaper than a DSLR setup.
- sambroner 6y agoCan you share more about this? What’s a capture card? And how did the latency turn out? I’m interested!
- kbouck 6y agocapture cards are devices primarily intended for game streamers to give your computer an hdmi input to stream/record games from a game console, but are also useful for other purposes such as turning your dslr into an expensive webcam. i have this one: https://www.elgato.com/en/gaming/game-capture-hd60-s-plus https://www.elgato.com/en/gaming/game-capture-hd60-s-plus you can find others from magewell i don't have measurements but the latency was indistinguishable from a directly connected webcam.
- stragies 6y agoIf you use the usb gadget mode of the raspberry pi to present the PI as a USB WebCam, you can forego the HDMI-connection, and thus the need for the HDMI capture card.
- lurquer 6y agoI've been trying to get a FPV drone camera feed into my Windows 10 computer so OpenCV can muck around with it. OpenCV easily recognizes Webcams, but sucks at picking up 'video adapter' kinda stuff. (That is, I'm going to be using an RCA to USB dongle, such as EasyCap.) If you can 'trick' OpenCV into thinking a webcam is attached at the USB, everything is golden. Can you describe this raspberry pi method of 'presenting' the device as a USB WebCam? That sounds promising... edit: Forgot to mention OpenCV is part of a c++ 64bit program I'm writing.
