Review – Opteka E-TTL / E-TTL II Off-Camera Flash Sync Cord for Canon EOS Cameras

I was looking for an affordable ETTL Flash Sync Cord and I found this Opteka E-TTL II for Canon Cameras, having use some opteka products and found them to be reliable, I decided to give this a try, hoping that I would be lucky enough not to experience some of the mishaps that other reviewers from amazon have mentioned on their review of this product. I mean for $19.00 + free shipping from ebay, it’s not bad. This same item is sold at amazon for around $25 by 47Street Photo.


  • Heavy-duty coiled cable (Extends up to 4 Feet)
  • Compatible with Canon Brand & Canon Compatible Flashes
  • E-TTL & E-TTL II Compatible
  • 1 Year Warranty

First Impression

It came in a nice little box, Opteka has redesigned their packaging for all their products, and it looks nice. After opening the box, and holding the item, it looks like the cord is built from good quality materials. Looks really great, and sturdy enough to handle rigorous usage.

Now the Testing: I first tested it on my Canon 20d with Tamron 17-50mm F/2.8 VC, in ETTL mode, the first shot was great, I was impressed. But that’s it, the next shot I took, I noticed that the flash output has been decreased significantly when I look at the back of my 430EX II, I saw that it’s in TTL mode, no mater how much I adjust my flash compensation, the flash output won’t changed. I replace the flash batteries with newly charged ones thinking that it’s probably because of the batteries, but output are still the same, the ETTL worked three times but that’s it. When I switch my flash to manual mode, the flash won’t fire at all.  So next thing I did was to try it on my Canon Rebel XS with 50mm F/1.8, the Flash didn’t fire at all, whether in ETTL or Manual mode. I decided to return it, and thankfully 47Street Photo has agreed to give me a full refund and they sent me a prepaid return shipping label.

Unfortunately like many others who bought and reviewed this product at amazon, I was really disappointed. This product is so unreliable I wouldn’t recommend it to anyone. If you are looking for a reliable Flash Sync Cord I would suggest sticking with your camera manufacturer.

Do you have any experience with a reliable third party flash sync cord? Which brand?
