Connect MiniDv camcorder via USB C & Firewire or MiniDisplay port

I'm looking to transfer MiniDv tapes to my 2017 Macbook Pro via a USB C connection. The camcorder has a Firewire 4-pin connection. Therefore I'll need a few converters in order to be able to import to my Macbook Pro. I'm wondering what adapters will work.

I understand that worst case I'll need a Firewire to Thunderbolt adapter and then a Thunderbolt to USB C adapter. I'm wondering if there might be cheaper option...

Would I be able to use an adapter like this which is a Mini DisplayPort to USB C instead of the $50 Apple Thunderbolt to USB C.

I know that Mini DisplayPort and Thunderbolt 1 inputs are the same shape, but will an adapter like I linked above be able to handle the transfer of video from my camcorder to laptop?

Since FireWire is consumer grade and well supported, you have identified the least expensive manner of connecting. Thunderbolt 3 does use USB-C connector, but unless you are willing to use a usb capture card or computer and pipe in HDMI, I would set aside USB adapters and stick with thunderbolt 3 to 2 adapter and then the thunderbolt 2 to FireWire adapter. All from Apple.

• Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter
• Apple Thunderbolt to FireWire Adapter

With tax and shipping that’s under $80 in USA.

No. You will need a Firewire to Thunderbolt adapter and then a Thunderbolt 3 to Thunderbolt 2 adapter.

USB-C is only the connector type, it’s still a Thunderbolt port.

You can’t use a mini DisplayPort cable because you’d be missing the Thunderbolt signaling. Yes the, the physical connectors are the same, it doesn't mean all the connector pins are there. Remember, DisplayPort is a component signal/protocol of Thunderbolt. In other words, a a Thunderbolt cable will support mDP, but an mDP cable doesn’t support Thunderbolt.
