i just had to post this, sorry if you think it's a waste of space or time. sitting in my office, nothing to do as usual, and have d2x/70-200vr on my desk. playing around with sb800, testing different settings for background light etc. my office is fairly large and is actually 2 rooms, conference area and working area. go to snap off a feww with flash to test ambient light and holy cow!, nothing, oh my god, what have i done. i need this thing for a shoot, on the weekend. three four clicks nothing, it won't fire. i am mad, getting ready to flame nikon. ok! enough ranting, i took the cf card out to download, and did not put it back in. well, i thought about all the dumb posts, about my camera does not work hello! hope this helps to put a smile on your face, it just shows, how dumb i am.
