[QUOTE="WayneF, post: 194391, member: 12496"] There is absolutely no need to try that one Dave. :) I believe you, but I cannot say it any other way either - Flash exposure depends on [B]the distance from flash to subject[/B]. NOT camera to subject. You can repeat that result with ANY fixed flash, in any mode. I'm using hot shoe iTTL instead of Commander, but it is NEVER about camera distance. The D lens distance does assume hot shoe flash (at same distance as lens), otherwise it is not applicable and ignored. So my link to [URL="http://www.scantips.com/lights/flashbasics4b.html"]Flash Indoors[/URL] is another subject, about some Factors of TTL Metering Exposure. D lens and FV Lock are BIG factors of TTL BL exposure, stuff that is good to know what to expect. Specifically, TTL BL simply does not act like TTL BL with FV Lock. Direct flash TTL BL being protected from overexposure by the D lens distance is bypassed if using FV Lock (and also, the D lens distance is poor at best in many zoom lenses, often counter productive). Balanced TTL BL flash in bright sun is bypassed if using FV Lock. It then acts much more like TTL mode, except Exif still reports TTL BL mode (which it ain't). This seems sort of a biggie. [/QUOTE]
