Nikon Speedlight SB-400

I did mention about Nikon SB-400 in my previous posting. Now i'm going to review this litte stuff. Overall, i'm very satisfied with the performance of Nikon SB-400. It gives me the option to have creative lighting. It is small, compact and most important is affordable. It uses only 2 AA-size batteries, which is very convenient as u can get the batteries in most convenience stores. The flash head can be tilted in 4 steps, horizontal, 60, 75 and 90 degrees. For me, it'll complement Nikon D40.
