Canon jumps on Thunderbolt

Canon first to jump on Apple Bandwagon

By Steve Hullfish | March 11, 2011


So, when Apple recently announced support for Thunderbolt the biggest question after the release by many in the video community was: "Who else is going to support this?"

The answer has come from a major player: Canon. This is a natural partner who can obviously utilize Thunderbolt's 10Gbps port.

Thursday Canon announced that it would be coming out with at least one video camera that would use Intel's Thunderbolt port.

According to Canon's Hiroo Edakubo, "We are excited about Thunderbolt technology and feel it will bring new levels of performance and simplicity to the video creation market."

Most of the players so far who have hinted at delivering products for Thunderbolt have been storage/hard drive related. Though AJA's John Abt has teased on the Intel site: "Welcome to the future, Thunderbolt technology enables the fastest and simplest I/O for connecting AJA's award-winning professional video capture and playback products to your laptop." And BlackMagic's Grant Petty also hinted, "Thunderbolt technology will revolutionize mobile media creation. It's a game-changer and will accelerate our ability to build the highest quality video creation products that are affordable to everyone."

If you've been living under a rock, or maybe haven't given it your full attention quite yet, here's the skinny on Thunderbolt so far:

Thunderbolt was originally code-named LightPeak and is an Intel technology that uses the same connection as the mini-display port on a Mac. It is designed for high-speed, dual-protocol (PCI Express and DisplayPort) I/O technology. Basically it's the next step after USB3 and Firewire800, with the twist that it's also a display protocol.


At 10 Gbps, Thunderbolt simultaneously delivers high-speed data and display transfers in each direction. At that rate, it is possible to transfer a full-length HD movie in less than 30 seconds or backup a year of continuous MP3 playback in just over 10 minutes. Cool, I was trying to figure out how to get my C-SPAN archive onto my MacBookPro.

Thunderbolt can be daisy-chained. Initially it will be released on Apple products as a copper-wire cable but will eventually utilize optical cables that will allow very long cable runs. The cable will allow power over the cable for bus-powered devices.

Thunderbolt is not just a cable and port. It transmits and receives packetized data - going both directions at the same time - with all the traffic handled by a controller chip in the computer and other external devices - like the newly announced Canon cameras. Intel is promising workstation performance expansion on a laptop. Obviously, with this type of throughput, the types of devices that will be able to benefit from this speed are things like hard drives, RAIDs, and probably IO devices like those by AJA and Blackmagic. This could also allow for "expansion chassis" type devices that will allow laptops to tap in to workstation-like power that was never before possible. For example, many people use workstations, including the MacPro towers, because they need the slots for graphics and video cards. Those cards could possibly sit in an expansion chassis or some kind of external device and be linked to a Thunderbolt-enabled laptop. Intel also claims that adapting existing I/O technologies, like GigE, FireWire or eSATA should be simple to do.

Beyond Canon and Apple, LaCie has also announced support for Thunderbolt. Others are sure to follow.

Looks like an great advance forward over SDI ...
BUT - still not a locking connector!!!

Maybe the physical construction will allow for some sort of mechanical locking mechanism? Cannot tell from the phots.

This is exactly the same as the mini-display port on any fairly modern Mac laptop. There’s nothing locking about it, unfortunately.

Regarding the “expansion chassis” concept: I think I recall seeing some info and pictures of some such device online somewhere several years ago. I’ve forgotten the details.

I see the 8GB RAM limit on laptops as probably the final stumbling block. Will we ever see laptops with 32GB or 24GB? Maybe this is the answer.

A chassis containing 32GB RAM (and other things like I/O cards, etc too) which a laptop can hook up to when needed. When on the road or at a customer the laptop’s internal RAM will be fine.

Maybe the RAM expansion concept could also be done with a docking station that has a Thunderbolt connection.

Forgive me for being cynical, but I don’t feel that “We are excited about…” and “...feel it will bring new levels of performance…”
amount to anything close to a commitment to support Thunderbolt.

What it sounds like to these jaded ears is “It looks good, we are going to sit back and see how everyone else reacts before we commit millions to retooling and re-designing for our products.”
