[QUOTE="WayneF, post: 349502, member: 12496"] Assuming your shoes have the tapped hole in them, then standard 1/4-20 NC screws will attach them. The flat plastic stands that come with the flashes would work for that, but metal seems better to me. My shoes were Stroboframe 300, which comes with the threaded knobs. The S1 slave mode ought to trigger all of them except the one the camera triggers (probably the near fill light, which happens to conveniently be aimed at main light). I think the YN565EX guide number is about correct, at least at 24mm. See [URL="http://www.scantips.com/lights/yongnuo565.html"]Review of the Yongnuo YN565EX Speedlight[/URL] about 1/3 page down. GN 58 (meters) is at 105mm zoom. At 24mm zoom, it is GN 28 (meters), which x3.28 is 91.9 (feet). I multiplied 91.9 by 1.414 to get ISO 200 value of GN 130 (feet), and therefore used f/13 at 10 feet (ISO 200), and I thought it was perfect, matching the GN. I'm not sure if the longer zoom GNs are as accurate, but 24mm zoom seemed right. And it is a full powered flash, it matches the SB-800 power, which is saying a lot. Certainly there are less expensive choices (speedlights too. :) ) I don't know where you are, but in the USA, [URL="http://www.paulcbuff.com/index.php"]Paul C. Buff Alienbees[/URL] are extremely popular, and there are different sizes, but more like $225 and $280 each. That's what I have, and they have advantages, esp service and support. IMO, these are the GOOD inexpensive ones. And there are several other brands too. I would avoid the cheapest (Ebay stuff), and be sure they are fan cooled, but there's many choices. FWIW, it has been several years, so I repeated the metering of the flashes Both SB-800 and YN565EX (individually) in same 45" white reflected umbrella. Manual full power, 24mm zoom. Metering at 24" from light stand, on 27" full umbrella shaft, 51" from apex of umbrella: Both flashes meter f/8 plus 0.4 stop (f/9.2) at ISO 100, and f/11 plus 0.4 stop (f/13) at ISO 200. [/QUOTE]
