    Not had chance to use the flashgun to its full potential so far, but it appears to do what is required. Considering a well known chain photography shop wanted £446 for the AF 540FGZ, it was a bargan at the price I paid. This flashgun appears to be far superior to others I have used on all settings. Dedicated to my camera (Pentax K2000D) there is a very great scope for the flash and camera together (TTL, Program, manual, shutter priority, Aperture priority), all work well. Though I must stress at the moment I am only playing with it and not using it for outside work (at functions). I will possibly test it fully over the Christmas period.
    The service received from Microglobe was also first class. I ordered at 4.30 in the afternoon on Monday and the flashgun was delivered by 8.30 on Wednesday morning. Packed in a sturdy cardboard box and well protected with polystyrene. and well sealed. Thank you for your brilliant service ... Duncan
