I saw all the reviews before I purchased the the flash and was soooooooo excited to finally get it, but after that very disappointed. The flash is not strong enough, and it's no stronger than the built-in flash on my Nikon D40. I was trying to capture the spontaneity of my niece Sweet 16 birthday party I was VERY disappointed with the pictures that I took with the flash. When I removed the external flash, then used the built in flash I have beautiful memorable pictures...

Bought this for my son for Christmas (for his D40). He appears to be very happy with its quality and compact size. Thinking of getting another one for my D80!
Rating: - Works great
A great performer. As an amateur it does evrything I need and more. Had the side shadows with the built in flash on my D-40-none of that with the SB-400. Still experimenting but no dissatifaction yet.

Had this item since Christmas ,so far pictures look good, not ready to review picture detail yet. The carry case is good, made well and does the job. What would have been real handy is if there was a way to attach the case to a camera strap...there is nothing. The device is so small it would be nice if it could be attached to a strap and therefore always available . Simple feature would make it so convenient.

I use it on my D300 with 18-200 lens to photograph my 1-yr old son. I need a flash since I usually take pictures in the evenings. (Winter days in Portland also do not offer much light indoors, so I use during day as well.) Small size and bounce function make it perfect for me - both attributes are critical for me. Stays on my camera 100% of the time, both turned on (camera and flash go into sleep mode) and ready for action. I get masterpiece shots of my son every day. Having camera ready to use in an instant makes the special shots possible. I always use it in the bounce mode with just a slight tilt down to add some light on the face and to put some sparkle in the eyes. I use ISO 400 to get some ambient light. Everything works perfectly all the time - exposure and colors. The only improvement I can think of would be adding head rotation to allow vertical composition with bounce off the ceiling; not a big deal though. Low cost is a bonus, but not a major factor for me. (BTW, I also have Canon 40D with 580EX and I practically don't use it anymore - it is just too cumbersome due to 580EX size. I also get better results with D300.) If my SB400 broke for any reason, I would instantly buy another one.
