> an Ethernet port !!!

Yeah, there can be a lot of bandwidth required. RAW images at 24.2MP are around 30-40MB (https://toolstud.io/photo/megapixel.php?width=6016&height=4016 https://toolstud.io/photo/megapixel.php?width=6016&height=40...) and at 20FPS you're above 1Gbps (which a crowded wireless network certainly can't handle). Add those bandwidth requirements to some of the real-time workflows professionals engage in today (see http://www.imaging-resource.com/PRODS/sony-a9/sony-a9A.HTM http://www.imaging-resource.com/PRODS/sony-a9/sony-a9A.HTM and the comments around 11:53) such as: "first Sony camera with an ethernet port. Have to be real time. Shows, presidential debates, every shot I took went right out onto the network as soon as I shot it." and "for major UFC events, it’s vital to be able to do a live workflow, where images are constantly going back to an edit station and go out to the world immediately. Not only the ethernet, but the wireless is key for social media outfits all over the world." and ethernet makes sense.

  usb 3 is 5Gbps, thunderbolt is 10Gbps, thunderbolt 3 is 40Gbps. i don't think it makes sense to put ethernet ports on anything smaller than a rack blade.

    If you're suggesting they went with a USB or TB ethernet adapter instead, think about the complexity of supporting the numerous available NIC chipsets on something like a camera...

      There is a Linux inside Sony Alpha. No problem with drivers :)

    They can also only go 5m, 3m and 3m, respectively, before interfacing to a computer (which then uses ethernet to go somewhere else anyway). Ethernet makes sense if you consider that images are going straight from the camera to the control room (which is hundreds of feet away, and possibly parked outside in a truck), and that there's likely already network infrastructure (switches and cabling) in place for dozens of other reasons.

    Ethernet provides (close to) the advertised bandwidth without any fuss and is compatible with everything. Contrast with the others you listed.

    I do. It's increasingly common to have a rolling NAS on film sets and being able to hook up the camera and storage with an ethernet cable is a no brainer for many productions. Time is money and video workflows have historically been a logistical nightmare. Generally when you're shooting narrative on a pro camera you have to stop every 20-30 minutes to swap media. I would much rather string a cable and have one less technical person and two more people in the art department for the same money. Media management is a huge bottleneck, not to mention a source of continuous low-grade anxiety.

Sony is better at being Apple than Apple is.
