The PENTAX AF160FC Auto Macro Ring Flash is uniquely suited for advanced close-up applications using the automatic exposure-control system of PENTAX digital SLR cameras. This unit offers smooth, even lighting for the closest subjects, while eliminating vignetting and subject shadow.
With a guide number of 16 at ISO 100/m, it provides ample lighting for small or large close focus subjects. The AF160FC's modeling light, with 4 white LED's, help preview flash exposure while assisting autofocus operation. Designed to offer uniform lighting on a subject to minimize shadows, the flash is ideal for close-up, portrait, product, dental and medical applications.

I use this flash primarily for photographing honey bees and other insects, but it's great for all types of macro photography and portraits. I preferred the coil cable on my old af080c. This one is a little stiff and bulky, but hopefully that means it will be very durable.I also like the fact that it has multiple manual power settings,an led lights for previewing and focusing aid, and multiple adapters.To sum it up, this flash has it all.
Great macro tool. Gives you the ability to obtain required dof when shooting macro. Integrated with dfa wr and non wr lenes,allowing it to mount to the dfa lens barrel rather then the filter ring on tip of lens, less stress. For non pentax dfa lenses the flash has adapters for other filter ring sizes. There is a T9-2x adapter available that also integrates with the flash this bumps the max magnification off the 100mm2.8 dfa from 1:1 to 2:1. The 160 has curve flash tubes the compition has smaller strait tubes.
