Pentax AF180FG is new mini flashgun for DSLRs and Ricoh GR III (and looks familiar)

Pentax has released a new hotshoe flashgun for use on its DSLR cameras and on Ricoh GR compacts. With a guide number of just 18 (m/ISO100) it is designed for on camera use for fill-in in daylight, or as the main light source after dark.

Pentax AF180FG is a replacement for the existing Pentax AF201FG strobe – and both are exactly the same size and weight and have nearly identical features. The only difference that we can make out is that the newer version has a slightly lower maximum output (the AF210FG has a guide number of 20 (m/ISO100)).

The AF180FG has a simple interface that offers a dial offering access to its four operating modes. In addition to a fully automatic TTL exposure mode, there are two manual options that provide either full or quarter power. There is an additional option for rear-curtain sync flash .

The head can tilt through ten different positions from -10 degrees through to 135 degrees for flash photography. The flash offers coverage for a 24mm wide-angle full-frame lens – extending to cover a 20mm lens, if the built-in pull-out diffuser is used.

Boasting a weatherproofed construction, the flash weighs 141g before you add the two AAA batteries that are needed to power the unit. A new set of alkaline cells should give around 100 flashes, with a recycle time of 6 seconds. You get a slightly better performance if you use nickel metal hydride rechargeable AAA batteries - with 130 flashes with a recycle time of 5 seconds.

The Pentax AF180FG will cost $199/£199 – the same price as the flashgun it is replacing.
