I am quite excited! I received my new Pentax AF 360 FGZ Flash on Thursday! I have used add on flash units in the past, but this is the first time I have had one with so many functions and flexibility. This new flash communicates with my camera, zooms in and out as I zoom my lens in and out, and helps my camera with its settings when I choose to bounce the flash off the ceiling, etc. I am having a lot of fun playing with it and seeing what new options it brings me. It is much more powerful than other flashes I have used in the past, so it will hopefully give me broader range.  I have also just received the Lumiquest Promax system, which allows me to attach various reflectors to my flash unit, such as white, gold, and silver reflectors, softening the power of the flash and offering slight colors to the flash light.
