Shooting tethered with a USB 3.0 camera has its challenges. Photographers using some of the most popular on the cameras on the market, including USB 3.0 cameras from Nikon, Canon, Phase One, Mamiya Leaf, Pentax, and Sony can experience dropped tethering connections or are unable to get a tethered connection at all. The TetherBoost Pro USB 3.0 Core Controller provides consistent power to maintain a stable connection for tethered image transfer when using a DSLR or medium-format digital back system connected to a computer via USB 3.0 cables – now at distances up to 65 feet. This streamlined solution in a durable aluminum housing alleviates current frustrations among photographers experiencing dropped tethering connections or who are unable to get a tethered connection started at all.
NYC DigitTech George Brooks explains why photographers need a TetherBoost Pro USB 3.0 Core Controller:
“Cameras like the Nikon D810, Canon 5D Mark IV Phase One IQ series, and Sony A7Rii that use USB 3.0 for tethering present a new issue. Unlike USB 2.0, USB 3.0 devices can draw a maximum of 900mA of current. This is no problem for the more robust ports on a Mac Pro or PC workstation, but the USB ports on MacBook Pros and iMacs do not offer the same performance. While they can generally supply enough current to sustain a connection with a standard 15-foot tether cable, the same cannot be said for longer cable runs. That’s where the TetherBoost comes in. For DSLR cameras that use the USB 3.0 Micro-B Connection like the Canon 5D Mark IV, 5DS, Nikon D810, and Sony A7Rii my experience has shown that a TetherBoost setup is required in order to use cables longer than 15 feet when tethering with a MacBook Pro. I like to use the TetherBoost when tethering to my MacBook Pro as well, just to be safe.”
