I bought this so cheap flash today at a flea store near my place. At first, I was thinking of not buying it since I dont think its necessary and will be suitable for my d90. But then this lady asked me to just try and after 30 mins of sweating coz of figuring it out -- it totally works. And when I went back home, I noticed that its suit for all Nikon AF lenses. Sweet. Im still learning! Ill show photos with flash on my next post.

PS: My Nikon D90 is really heavy and its much heavier with this flash. Shoulder sore.
