I want to shoot tethered with a Hasselblad H3D-39, which connects over FireWire 800, but my Windows laptop only has USB ports. Can a FireWire-to-USB adapter make this work, and will Phocus or Lightroom recognize the camera through that setup?

As far as I know, there's no Firewire-USB adapters available. Emulating Firewire over USB is quite difficult, as technology is so different.

  • In USB, there's no guaranteed bandwidth available.
  • In Firewire, there is (which is really important for streaming video)
  • Firewire allows DMA (Direct Memory Access), while USB does not. That means special driver emulating DMA is required for Firewire adapter. This is a huge performance hit.

Also, do note that there's no Firewire on newer Macbook laptops (since mid-2009), according to Wikipedia page. However, official Apple-made Firewire-Thunderbolt adapters are available (29€).

No. A simple FireWire-to-USB adapter will not let a FireWire-only Hasselblad H3D tether to a USB-only computer.

FireWire and USB are fundamentally different interfaces. FireWire supports features like direct system access and guaranteed bandwidth that USB does not provide, so a passive or generic adapter cannot make the camera appear as a normal tethered device. Because of that, Phocus or Lightroom would not be expected to recognize the camera through a basic USB adapter.

Some niche converter devices exist for very specific FireWire uses, but they typically only support limited device types and are not a general solution for camera tethering.

In practice, you need a computer with native FireWire support or a supported expansion path that provides real FireWire functionality, not just a plug adapter. On some systems, Thunderbolt-to-FireWire solutions can work when true Thunderbolt is available, but USB alone is not enough.
