Does everything it says it will do. Came with a remote as well, which didn't work all that well. It drained my batteries very quickly. It moved around a tiny bit no matter how tight I could get it on the body of my D90. It also would disconnect power a little bit for a split second. Which might be the cause of the batteries dying while my camera was in my camera bag. I'd have full batteries, not use my camera for a week. Then they would be half dead or more when I used my camera. Other than that, it worked. I'd buy one again if I didn't have the money for the Nikon version. Just remember to remove batteries while your camera is being stored.
