[QUOTE="WayneF, post: 414393, member: 12496"] How far from camera to subject? If camera is like 2 feet from subject, and flash 5 feet behind camera, that's a big difference (2 vs 7) that should show up. But if like 10 feet and 15 feet, less difference (still maybe one stop difference). The SB-700 (and specifically the Nikon system) is TTL BL, unless spot metering. Menu says the generic TTL (Through The Lens metering), but the system specifically does TTL BL Balanced flash (unless Spot metering). The Metz has the TTL vs TTL BL menu to override, TTL menu doesn't need Spot, but Spot will still change its TTL BL to be TLL. Test is about Matrix, Center Weighted, and Spot metering. AF-S/C won't matter. Of these, only Spot switches TTL BL to TTL (Complications: Tilting head up also switches to TTL. And FV Lock is still TTL BL, but it switches out D-lens check. Not all cameras have FV Lock, but with TTL BL direct flash behind camera, the test could just specify Matrix metering, but with and without FV Lock ... same thing. I think it is a terrible flash design situation. We learn to use it, but I'd like a camera menu to disable D-lens meddling. TTL vs TTL BL ought to be a camera menu too, or maybe a button on back of camera.) I appreciate the try, but I am guessing that your equal results suggest all tests were Spot metering? Switch to Matrix or Center, and at least the SB-700 ought to show a big surprise (in the test situation). [/QUOTE]
