Nikon SB-900 Expert Reviews
Warehouseexpress reviews the Nikon SB-900 and writes;
” Throughout testing I found the speed of flash recycle was fine as I had expected, as was the repeat flash output accuracy when in manual mode.”
Nikondslrs reviews the Nikon SB-900 and writes;
“This flash unit is strictly for professional photographers that want to get the most out of their lighting. Size and price may be the SB-900’s biggest stumbling blocks but if you need power, speed, and flexibility, make space in your camera bag for this impressive flash.”
Photoreview reviews the Nikon SB-900 and writes;
“We were only able to test the SB-900’s capabilities as a single flash unit and in conjunction with the D700’s built-in flash. And, not having reviewed the SB-800, we were unable to compare the performance of the two flash units. Suffice it to say we found the test sample to be an excellent performer that delivered an evenly-exposed set of test shots with different camera-to-subject distances and focal length settings.”
Ephotozine reviews the Nikon SB-900 and writes;
“I’ve never been a fan of using flashguns as I prefer studio lights or ambient light, but I have to admit that if all flashguns performed to this standard, I’d use one. The build quality is excellent as is the menu system and I’ve even got to enjoy the funny noise it makes when it starts up.”
Momentcorp reviews the Nikon SB-900 and writes;
“Other than that the SB-900 is a great upgrade of the SB-800. The Nikon SB-900 is way faster to work with, quicker to set up, shorter recycling times, and last but not the least greater coverage than ever before. The SB-900 is of course compatible with all the Nikon CLS equipment and will work with pretty much all the Nikon Dslr cameras.”
Kenrockwell reviews the Nikon SB-900 and writes;
“The only significant advantage of the SB-900 over the SB-600 and SB-400 is that the SB-900 (and SB-800) have a built-in white card to provide a catch light when bounced. I use a white Post-It Note on the other flashes to do the same thing.”
Bythom reviews the Nikon SB-900 and writes;
“Other than that, the SB-900 should be pretty straightforward for previous Speedlight users. The head swivel mechanism is still the same (though you can go the full 180 degrees in both directions now, and the primary Mode and Zoom buttons are the same. We still have the flip lock lever to secure the flash in the hot shoe, and the small diffuser and white reflector still pull out from the top of the head the same way. The battery compartment door is slightly better than the SB-800’s and seems less flimsy, but it will still tend to pop open when the flash is dropped.”

Nikon SB-900 Features & Specifications
The SB-900 i-TTL Speedlight leads the Nikon Creative Lighting System by delivering the portability, power, and versatility to support any photographer’s creative lighting imagination.

Photographers also have the choice of three light distribution patterns: standard (for general illumination), center-weighted (for portraits), and even (for groups or interiors).
Finally, the SB-900 automatically identifies mounted color gel filters and adjusts the camera’s auto white balance setting (available with select Nikon digital SLR cameras). Other details include automatic FX/DX format identification; user-friendly firmware updating; flash tube overheat protection; and a drip-proof mounting foot cover.
