I do not know where to post this, so I do it here. I plan to buy a flash for my digital camera Nikon D70. I hesitate between the Nikon SB600 and SB800. What is the most difference between these models and what is the ustility of the SB800 additional features ?
I'd suggest the SB600 over the SB400 for a couple of reasons. My SB600 had a motorized zoom head that matches the focal length of my Nikon zoom lens, automatically. It also tilts vertically AND horizontally, which is very useful for those times when you want ceiling bounce flash and have turned the camera sideways.
The SB800 has more power and a few more features, but on a D40, it's capacities most likely wouldn't be appreciated for it's extra cost.
