Yongnuo Speedlite YN560 IV

Featuring both a 2.4 GHz wireless radio transmitter and receiver, the Yongnuo YN560-IV Speedlite is a long range manual flash unit capable of triggering other flashes from up to 328' away as well as being triggered with the RF-603 and RF-602 wireless transmitters. The YN560-IV is powerful with a guide number of 190' at ISO 100 and 105mm. The unit is also quite versatile with a zoom range of 24-105mm, which is able to be expanded to 18mm with the built-in wide-angle diffuser. Additionally, this output can be adjusted from 1/1 to 1/128 power in 1/3 and 1/2 EV steps.

Full bounce and swivel lighting is possible due to -7 to 90° tilt and 270° of rotation with the locking flash head. The flash can also be triggered optically with either instant sync or skip pre-flash options for simpler off-camera firing. A built-in PC sync port further enhances the flash's connectivity and a Multi mode allows for stroboscopic lighting effects. The flash runs on 4 AA batteries and has a recycle time of about 3 seconds. It comes with a protective case and a stand.
