Hi, thank you for contacting My name is Russell. I will do my best to provide the right answer to your question.

How long has tethering been working, on this same computer with this same operating system version, with this same camera?

How old is the camera? in months or years since you bought it.

Has the camera been dropped or otherwise subjected to mechanical shock(s) in its lifetime?
Has the camera been operated in or subjected to, temperatures below 32 degrees F (freezing point) or above about 100 degrees F ? Has it ever been subjected to a humidity higher than 85 % ?

Hi Russell, I've only been shooting tethered for 6 months, always on my mac book pro OS 10.5.8. the camera is nearly 5 years old but has never been dropped or had temp issues!


I think the digital port has had it, can't see that it can be anything else which is why I thought i'd ask you! I've tried it with 2x new cables..


Many thanks

Well, Steve, it still might be that the digital port that has the problem is on your computer. If you had two Firewire ports on your computer (I understand that to be very rare), you might try the other port.

If you already have, or there is only one Firewire port on your machine, then these possibilities need to be mentioned:

1. you could (if your camera model allows it) try using a USB cable and USB port instead. (I don't know that this is even possible.)

2. you could try the camera on a different computer.

- And also: does anything else about your camera work through the cable? does the computer acknowledge that it is present, when it is connected? can you take snapshots as opposed to tethered video, and transfer those snapshots to the computer, at all? Your Canon 1Ds is, after all, a fully independently capable camera.

Can you even take photos or video with the camera on its own, and see those in Review mode?

Being a complex Canon camera, it needs to be asked: when you are connected, A. are you in the right camera Mode? and B. does any icon appear on the camera's screen showing that it senses it is connected? (I can look up and tell you the details of what to look for, if you are uncertain.)

Computer port is fine. Camera doesn't connect to second computer. Its a 1Ds so doesn't shoot video. The icon does not appear on camera screen and yes I can shoot as normal to the card! Are you not familiar with this camera?

Expert:  Russell H. replied 4 years ago.
I had to look up the model #, I admit.

It does sound as if the part of the camera that communicates with computers might be broken or dead.

Since I am out of other ideas about the case, I am Opting Out, opening the question to any other Expert who might have a different approach, or something to add, to offer to the case.

(I am not ceasing communication, just opening the case to others.)

Hi. My name isXXXXX a camera repair technician with over 20 years in the business and I'll be glad to help you with your question today.

What usually happens is the cameras firewire port breaks a leg to the main circuit board. If you're lucky, that's all that happened to it this time. The port itself is available separately from Canon but you'll need a technician to install it. If the fault is in the electronics it requires replacing a main circuit board and reprogramming. This is going to require some troubleshooting by a good repair shop. Below is a link to a directory of repair shops, one of which should be in your area and able to help you.
