The YN560 IV speedlight took the 560III and introduced a built in controller as well. Now you can have it all in one nice package. Complete wireless radio signal control is built into the speedlight. Using this as a master flash you can control up to 3 groups of speedlights, 560iii or 560iv. You can make all the adjustment to the power output from this speedlight and it will send the information to the ones that you are using off camera. No need to walk over to make those adjustments.. Portrait photographers, Real Estate photographers and more love this speedlight for its ease of use and its tremendous light output.
Built with Volusion.
