Got one of these Digital Concepts flashes this week for use as off-camera slave to my K20D built-in flash.
In this set-up the 'wireless' in the slave is optical flash detected from the camera 'built-in' flash.
P-TTL is only available when mounted in camera hot-shoe. (Where it easily out-performs the 'built-in'.
Pre-flash and light-meter reading by the camera produces slave 'pre-ignition' and incorrect light reaidng - results in black pictures.
Taking lens off 'A' setting and running camera and slave in full manual mode works very well - but you need to learn a lot about guide numbers, f stops and flash durations.
The Digital Concepts flash gives you full control in manual mode including durations of flash down to 1/16.
The vendor advert and the flash instruction sheet make no mention of P-TTL wireless connectivity.
