I am a passionate amateur photographer. I do not suffer sub-standard equipment very long. While I can't afford the very best equipment, the equipment I buy had better be worth my hard earned money. I originally was going to buy an SB-600, but they were discontinued, so I bought the SB-700. After reviewing the specs, I found that the SB-700 actually has slightly less flash power than the SB-600, and some other minor differences, that would seem to make it a lesser flash for more money. I wasn't too happy, but I needed a flash, and didn't want to go high-end, because the more expensive flashes were quite costly, and had functions I really didn't need. I got the flash out of the box, loaded the batteries, hooked it to my D7000, and started to shoot. I was frankly amazed. The shots looked like natural light shots. I used a snap-on diffuser to soften the light, and angled the flash head at 45 degrees, and the pictures came out really, really well. My first real test of the flash was at a friend's birthday party. No matter if the subject was back-lit by a window, or in shadows, or with a dark wall, the photos were balanced and crisp. None of the usual flash pictures where the foreground is blown out and the background dark. The flash filled in when it should, and fully illuminated when it should. Nikon has figured out how to get their cameras and flashes to work together with perfection. You may need to adjust FV or EV for personal taste, and pay attention to WB (2 colored filters come with the flash to compensate for artificial light spectrums), but the flash really works very well. The only thing I would suggest is to READ THE MANUAL. There are some important settings that make the flash work much better if you pay attention. I have not tried the flash in slave mode, but I would expect it to work as well. It's very well thought out and easy to use. I only have one small gripe. The battery door is rather flimsy, and doesn't open in the way you'd expect it to open, so it could easily break if you get all macho with it. Other than that, this thing rocks!
