Yongnuo Speedlite Transmitter ST-E2

Picture by Yongnuo

The Chinese Strobist blog has published a detailed review comparing the performance of the Canon ST-E2 Speedlite Transmitter and the new Yongnuo brand model (not yet released).

The testers extensively evaluated the design, controls, range, and performance of the Canon and Yongnuo units against each other. Results and conclusions are summarised and averaged in the table below. Most notably, the Yongnuo model offers a swivelling head, AA batteries and a longer range than the Canon.

Where to buy

The Yongnuo ST-E2 is slated to be released “by the end of the year”. Yongnuo EX speedlights compatible with the Canon infrared wireless system are planned for 2011. Both will be available upon release from the official Yongnuo eBay store and other Yongnuo resellers.

    awesome, can’t wait to get my hands on one of these.

  • LR Editor

    Latest indications from Yongnuo suggest these will be released next week at a price of around US$90.

    the yongnuo ST-E2 is selling on ebay now. look this page, Yongnuo ST-E2 maybe it’s unexpected.

  • Peter

    I really cannot find that US$90 price on anywhere yet. Can anyone locate that price for me? I want a set badly. The cheapest I can find currently is http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=170545956810 from Ebay. I tried to locate that seller’s own website and that’s even cheaper than his eBay…But still I cannot find even the US$120 described in other groups(not to mention US$90)

  • Frederick

    Yes. The YongNuo ST-E2 has been released by some resellers online already! The cheapest I can find currently is US$139.99 from Ebay. I tried to locate that seller’s own website and that’s even cheaper than his eBay…I am very budget-minded and still wondering if I should go for other solutions like TR-332 over this one.

    Can YongNuo version turn off the flash trigger function and function purely as AF assist light source to save battery and red flash?

    I’ve got this and the canon version. I found the recycle time on the Yongnuo version very slow compared to the Canon, over a second. I think this is the downside of the more powerful beam, and cheaper batteries. You can see a short review here:

    wow, when this yongnuo came to indonesia, cant hardly wait^^

    Having tried a number of 3rd party flash guns and transmitters, many of which do not stand up to the test of time, I decided to stick with either the manufacturers own or certainly the bigger names. You cannot be left wanting in the middle of a wedding or commercial job.

    As for transmitters, too frequently I found issues with the infrared losing connection in bright conditions or where I wanted to hide the flash such that line of sight was obscured. I’ll stick with my more expensive Pocket Wizards, even though they are more expensive and now with the TTL minis, they’re fantastic.

    Hi there, thanks for a great informative website

    I bought a YN ST-E2 and it wont work with my EOS 600D, but works fine with 5dmk2 and 550D, did canon change the ttl protocol? Is there a qyuick fiz that you are aware of or could you suggest a workaround – im a bit desperate with getting this unit and not getting it to work

    Thanks in advance

      Apparently, yes they did change it. Not sure what the solution is, other than only use it with your older cameras…?
