YongNuo YN-560 IV Speedlite
With a 190' guide number at ISO 100 and 105mm, the Yongnuo YN560-II Speedlite is a powerful manual flash unit able to be triggered in a variety of methods. The flash can be triggered optically with either instant sync or skip pre-flash options for simpler off-camera firing. Also, the unit is 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. 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.
