It’s surprising the difference one cable can make to data transfer speeds, especially as the cable length extends, not all cables are made equal.
That’s instantly apparent as the TetherPro cable is plugged in, everything about it from the bright colouring, length, to the thick diameter and reinforced connectors are bigger and more industrial than your standard USB cable.
Although primarily designed for data transfer the TetherPro cable will also sustain 60W of power delivery if you need.
At 4.6m that’s quite an extension and will suit most small to medium-sized studios.
I’ve used a Sony A7 III connected to a MacBook Pro running TetherTools own Smart Shooter software in this test.
Plugging in and loading up, and the camera is recognised quickly. Also, the delay between the camera and the LiveView preview is minimal if at all.
Taking a few frames and the speed is close to instant, proving a fast connection has been made between the two devises.
I switched between Sony’s Image Edge Desktop, which I’ve been using for several years, to Smart Shooter. There are a few distinct differences, the main one being speed.
After a few shoots getting used to the Smart Shooter software and testing the cable, I’m impressed. I’m used to a slight lag before the images arrive at the screen, but the process is quick and fluid.
But how fast is that connection? To test I disconnected the camera and replaced it with the excellent GNARBOX 2.0. If you haven’t been introduced to one of these incredible boxes, then check out the full review here.
Checking the transfer speeds and the read speed came in at 312MB/s and write of 282MB/s. These speeds are as fast as most SD cards, so to have this transfer speed through a cable of this length is superb.
Compared to a cheap USB Type-C cable measuring 2m, not quite the 4.6m, enables transfer speeds of 38mb/s read and 26MB/s to write, which is a huge difference.
The transfer speeds are just part of the story in a busy studio or location shoot. The cable’s weight and quality are also essential. If you think about it the cable will be dragged around the studio floor as you shoot. This means that the cable exterior and connectors need to be tough and well insulated and protected.
The TetherPro cable doesn’t let you down on any front; the right angel connecter is tough and easy to secure into the camera. Likewise, the computer end is similarly reinforced.
I usually use a Tether cable in the studio, the excellent AREA51 that I looked at last year, here the TetherPro is a step-up on that build quality.
Measuring the difference in speed between the two cables and the AREA51 cable comes in 249MB/s, and 248MB/s write so quite a close contest.
When it comes to the cable itself, it’s double the thickness of a standard cable. Over several weeks of use, this has stood up to being dragged along studio and workshop floors and being trodden on, slept on by several dogs and generally abused as cables tend to be.
After an extensive cable test, I can say that there’s nothing to fault about the cable’s speed and reliability.
