YONGNUO YN560 IV Review

This is a powerful flash, with a guide number of 190 at ISO 100. It can illuminate the scene of your shot, even if you're taking photos in the dark and the object is further away.

This flash can take sharp images of fast movement and pictures where the object is sharp but the background is blurred, if used in slave mode with speedlights with HSS capability, like YongNuo YN-568EX.

This flash fits ISO standard shoe that most modern cameras have, including Canon, Nikon, Pentax, Olympus, Fujifilm, and Panasonic cameras. Although it still is a good idea to double-check if this flash is a fit for your camera in terms of voltage.

YN560 can be used to activate other camera flashes from up to 27 feet away thanks to the built-in wireless transmitter. It can also be used in slave mode, activated by another flash or a wireless trigger. You can create groups of connected flashes with models YN560-IV and YN560-TX and use wireless triggers: RF-603 (I/II), and RF-602.

YN560 is faster at reaching its full power after being triggered than an average flash. It's recycle time is three seconds, while many brand flashes (Canon, Nikon) take as long as six. It's even faster if you connect your flash to an external battery pack via the HV port.
