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)).
