Thanks for the replys
The hover fly was 1/125, f9 ISO 100, I can't get the camera(K20) to shoot any faster than 1/180, I don't know if you can ?
The flash comes with 4 mounting rings 49,52,58 and 67mm. The frustration when it arrived, the Tamron 90 is 55mm..........lightning speed to the camera shop and back in record time,$18.00 lighter of pocket ,55-58mm step up ring in hand and right to go.
I've only used the Pentax flash on manual so far, I find it easier to control. One thing I don't like about this flash is the refection, although on occasion it looks appealing, it's a bugger to photoshop( I'm learning) out if required.
