Pentax Flash AF 180 FG
This compact, lightweight auto flash features a maximum guide number of 18 (at ISO100/m) and a dustproof, weather-resistant structure with 18 sealing parts across its body, including the hot shoe.It provides simplified operation: a single turn of the discharge mode dial, which also functions as the power switch, makes it ready for flash photography.
It also provides other useful features, including: a tilt head mechanism which moves a maximum angle of 135 degrees for bounce flash applications, to capture soft, natural images; and a removable wide-angle panel to cover an angle of view as wide as 13mm (when mounted on an APS-C-format digital SLR camera).
