Following the release of the YN-622C flash trigger for Canon cameras, Nikon users are to get the same treatment, with a YN-622N for Nikon. The upcoming radio system — which allows the photographer to use speedlights off-camera while retaining i-TTL control — was officially revealed by Yongnuo engineer Guanchao Liang, speaking to the Flash Havoc weblog.
A technical datasheet has not been released to the public, but Mr. Liang was quoted as saying there would be “a couple of unique features” in the YN-622N, without specifying what they might be.
Because of the different ways in which Nikon and Canon flash systems work, it is likely that the YN-622N will have a much more limited set of capabilities compared to the YN-622C. On EOS DSLRs you can adjust your flashgun from menus on the back of the camera, which is essential since the Yongnuo transmitter has no LCD or control panel to speak of. Nikon cameras do nearly all of their adjustments exclusively on the back of the flash itself, so the YN-622N may be not much more than a fancy “wireless TTL cord” à la the Pixel King triggers.
Upon release (the date of which is to be announced) the Yongnuo YN-622N for Nikon will be on sale at the Yongnuo store. The price will probably be exactly the same as the Canon version, which is already widely available for US$83 a set.
