Ricoh introduces weather resistant LED flash units for Pentax DSLRs


Ricoh today announced the launch of two weather-resistant auto flash units -AF540FGZ II and AF360FGZ II ,for Pentax DSLRs with a maximum guide number of 54 and 36 at ISO 100/m. These units are designed to provide solid, dependable operation even under harsh outdoor conditions including rain and fog. With 28 seals applied to crucial parts of the unit body including the hotshoe, these flash units feature highly dependable weather-resistant construction. By coupling one of them with a camera body and a lens that feature the same weather-resistant construction, the user can create a highly reliable weather-resistant digital imaging system.

Both Ricoh auto flash units AF540FGZ II and AF360FGZ II incorporate a newly designed, high-intensity fixed-light LED light in their body. This white LED light comes in handy not only for close-distance movie recording, but also for still-image shooting requiring extended exposures. It also functions as a catch light in portraiture and an AF assist light in the dark. The user can customize the flash operation by presetting as many as nine different flash functions to their preference, including the on/off of the catch-light function using the LED light and the choice of the flash discharge mode in still-image shooting.
