Chinese manufacturer Yongnuo has been a popular source of affordable speedlights for photographers in recent years. One of its latest units really steps up the game in the technology department though.
What’s more is that Yongnuo also makes the YN-E3-RT transmitter that includes all of the features and functionality of the Canon ST-E3-RT. Yongnuo’s version actually adds a few features, including an AF assist light and second curtain sync in manual mode.
While I haven’t tried either of these Yongnuo products, the price makes them very tempting to give a shot. The Yongnuo YN600EX-RT is widely available for a $188 buy it now price and the YN-E3-RT transmitter runs around $120-$130 fixed price. You can buy the both of them for about $300 as a kit.
Compare that to the $500 asking price for the Canon EX600-RT and the $280 price of the Canon ST-E3-RT transmitter unit. While you are likely going to encounter challenges with any required repairs, it would hard to blame the frugal photographer for going the Yongnuo way to grab Canon’s latest Speedlite technology. You can find them both from Chinese sellers here on ebay.
