The YN-560 III is an excellent manual power flash when TTL is not needed (e.g., in studio photography). It's distinguishing feature is an integrated radio receiver with multiple trigger options from three current-generation products. A Yongnuo RF-603 II is an affordable radio transmitter/receiver. I intended to use one on my camera (and more on my non-Yonguo flashes), but I opted for the Yongnuo YN560-TX controller when PhotoGear.com recently had a sale. The YN-560-TX goes beyond triggering, adding radio control of power and zoom for up to 6 groups of YN560 flash, very useful when flashes are above eye level on light stands. A YN-560 IV flash can also serve as master, but I prefer having less weight on my camera and generally do not want light coming directly from my camera when shooting people. So the YN-560 III is the perfect off-camera flash for me. I have two YN-560 III flashes (with the Nikon-style foot) triggered by a YN-560-TX (again for Nikon) on an Olympus E-M5 camera. They work properly together, and the light from the Yongnuo flashes correctly triggers optical slaves on my Nikon flashes. The quality of construction (sturdiness of the plastic body, non-removable battery door hinge, and head pivot smoothness) on the Yongnuo flashes is similar if not better than on Nikon SB-800 flashes. I like that no rubber button needs to be squeezed on the head before it turns or tilts through detent positions. Moreover, the Yongnuo buttons are easier to push than Nikon buttons while still working consistently. The YN-560 III does have deficiencies. First, the vertical viewing angle on the display is narrow. That makes the display very hard to read when the flash is high on a light stand or perhaps close to the floor. Before I used the YN560-TX controller, I needed to move my head around a lot to find the right viewing position or ended up lowering the flash to see it sometimes. Second, the low battery indicator and associated beep, only activate when the batteries are a few shots from becoming unusable. A continuous battery level meter would be nice, but the low battery indicator and behavior on the SB-800 is actually worse (flash goes to sleep with no audible warning and requires button press to wake). Third, like many third-party flashes, a ring must be screwed tight to lock the flash to a hot shoe. The screwing causes a locking pin to extend and retract, which is the same as on a Nikon so it is secure. It just takes more time than flipping a lever. Finally, the LCD backlight activates for a short time only when its button is pressed; it does not turn on automatically when other buttons are pressed. These issues are not showstoppers and I find myself preferring the Yongnuo flashes over Nikon flashes now. I am positively surprised at the overall quality of YN-560 III. The Yongnuo product provides a high level of functionality and outstanding value.

I owned multiple camera and sometimes I uses it simouslatanously so I won't be able to switch by taking my flash on and off, that is too much trouble, the sad thing is, I am just an amateur and I won't have able to purchase OEM flash for all my camera, that is a bit costly and overrated, so I guess the yonguo 560 III might be the perfect option, I can buy 3-4 flashes with the same price that I can only buy for 1 OEM, the quality is great , work both for wiresless slaves as well as a master with triggers !!

For the price purchased and the functionality available in this Chinese made product, the quality is exceptionally better than expected. Performance is on par and would highly recommend this to any amateur just getting into photography. Very happy with this solid performer !

Third one I've bought.

Incroyable qualité. Parfait pour l'éclairage en manuel et se faire un petit studio !

Great product, works as expected!
