Hello. I have a couple of AF-500-FTZ questions: 1)Guide Number-164/ISO 100. Is 164 an accurate guide number for this flash? I realize that flash manufactures tend to over rate their guide number, but I thought I read a comment here that Pentax uses the flash zoom head at telephoto position to obtain the high guide number. I am not sure that has any relevance to the actual guide number.
2)I am looking at this flash for Wedding and other event photography. I have the AF-280-T, which I like a lot,but I need more power. I like to use Reala film, but with an ISO of 100, I find the AF-280-T not quite sufficient. I will be using the flash with my PZ-1P. I also have an LX but it is my understanding that the AF-500-FTZ is not compatible with it. As always, thank you. Someday I hope to contribute an answer and not just ask questions. Francis
