The new AF540FGZ II and AF360FGZ II take their older namesakes, and weatherproof them to bring powerful strobes to photographers that want to be able to shoot in rough conditions. Pentax's weather-sealed cameras and lenses have a well deserved reputation for toughness, and adding a strobe to the mix will round out your kit bag. In addition to 28 weather seals, both flashes also offer LEDs for video or long exposure illumination. The AF540FGZ II features Guide Number 178 at ISO 100/ft, a five second recycle time, and will be available for $629.95 next month. The AF360FGZ II has Guide Number 119 at ISO 100/ft, and a 2.5 second recycle time. It will go for $429.95.
