|The SB-900 is perfectly adapted to both DX and FX formats, and will automatically select the appropriate light distribution pattern according to the sensor format of the camera to which it is attached. The SB-900 also automatically detects the fitting of fluorescent or incandescent colour filters, instructing the camera to switch to the appropriate white balance setting. Designed for today's high speed digital image capture, the SB-900 handles repeated firing at high power with an improved booster circuit for high-speed recycling and includes a built-in thermal sensing system that protects the unit against overheating. It is fully compatible with the other Speedlights and accessories of the acclaimed Nikon Creative Lighting System and can be easily incorporated into multiple-flash lighting set-ups.|

I have an SB900 and agree with all the positive comments posted in other reviews, however I want to challenge those who are posting stories about thermal shutdown to supply some additional information about what situations really cause the flash to shutdown.
I've been using my SB900 for several months now, and I've never experienced a problem with the unit shutting down, so I thought I'd try a simple test.
I installed a set of brand new lithium ion batteries in my SB900, set it to full power manual mode, and hit the flash button manually as soon as the ready light lit - that's about one full-power shot every 1 or 2 seconds. I did this until the batteries were drained (that is, until it got to be about 10 seconds between flashes - that's a few hundred full-power flashes in a row).
Never once did the thermal protection circuit kick in...in fact, the temperature display barely moved for the first 50-100 shots, and throughout the test, even when I could feel the batteries getting warm, it never went much above the 50% mark. My test was indoors at an ambient temperature of about 70 degrees.
I tried other settings - repeat flash, flash with my D3 firing at maximum continuous speed, etc. But I could never even come close to driving the flash to shutdown. So perhaps Nikon fixed the issue, I'm just plain lucky - or it has to do with the type of batteries or maybe other accessories used.
With this issue out of the way, I'm able to give the unit an unqualified 5 star rating as it's simply the most capable and easy to use unit I've ever owned.
The SB900 is a great flash, I own 4 of them. It comes with a nice soft case and a set of colored gels.
It is compatible with Nikon's CLS system (creative lighting system).
It is large compared with the SB600 (I own one of those) but the menus are much better to navigate.
It also features a "thermal cutoff" which shuts it down to prevent overheating.
There is much over hype about this. What actually happens is during rapid full power flashes the batteries get hot so it shuts down to prevent overheating. This feature can be shut off though I don't recommend that and leave mine on all the time and have never had it kick in.
Heck the 900 is Nikon's flagship / top of the line speedlight so of course its a great product.
If you just need a strobe for off camera / manual lighting ala strobist you could go with much cheaper models like the Lumapro's sold by Midwest Camera Exchange, they are about 1/3 the price but are not ttl compatable, full manual only.
This is a great flash in spite of some of the thermal issues that have been posted. I have used this flash that was bought used, and the performance of the flash is true and it does what they say it will do. It is a work horse.
The i-TTL works flawlessly and works well with other NIKON speedlites with Advanced Wireless System (AWS). I was impressed with its functionality and how easy it is to control the flashes from the camera. It is intuitive and easy for even me with first time use. You will see the difference in your shots immediately.
I also have and SB-700 that does not have the thermal alarm shut down issue. The SB-900 has an alarm that warns you of the temperature (which can be shut off or made silent). With heavy use it has triggered on me. With a brief pause in shooting it was back to normal. This could be frustrating for some but it is like a battery running out at the wrong time. It is just bad timing. It happens so get a life or have a back up flash.
This is a powerful flash that puts out a great deal of light and covers all the area requiring a speed light. I have used it with the Gary Fong collapsible in a church to photograph a choir and it did the job flawlessly. It is a tight fit due to the size of the flash, but it works with the diffuser. This thing is bigger that I had imagined, but it does the job. I am very pleased thus far. Great Flash and hard to beat.
Well what can I see but this is THE flash to have. It takes some learning as well as getting used to, I highly suggest getting rechargeable batteries as they last longer/work better plus it really helps keep the unit cool. I didn't realize how big the unit was until I got it next to my SB800 and it is truly a monster. The only issue I have however is setting off the temp alarm but if it wasn't for the fact I shoot in high temperatures I wouldn't have the issue as much I'm sure. The nice thing is I don't have to worry about burning out the unit like with other models. I plan on getting the external battery pack which others have said basically eliminates all heat issues.
This is Nikon's flag ship flash of the Nikon speed light line. Great flash very versitile. The only draw back to this flash is it is big and heavy. Also if you use the flash alot you are going to need a battery pack and it will overheat. Unless you take alot of pictures quickly this really is not a problem. Now Nikon is releasing a new version of this flash called the SB 910. It is basically the same flash, but cost $50 more.
