Nikon Speedlight SB-900 Flash

Nikon SB900 on its flash standThe speedlight SB-900 flash is the current flagship model from Nikon and designed for professional users. It’s expensive, feature laden and built like a tank, and looks best on one of the bigger bodies such as a D300S, D700 or the D3. But you can use the SB-900 with a small DSLR camera like the D3100 as well – that’s not a problem at all.

It just looks a bit funny when the flash is (seemingly) bigger than the camera body. Users of pro bodies not only have a more balanced combination, but they will also potentially make more use of the professional features (at least if they know what they’re doing with their gear).

Speaking of features: there is the widest zoom range of any shoe mount flash today, reaching a full 200mm in tele position. The flash head allows a full 360 degrees rotation. The SB900 comes with “auto” and manual mode on top of the digital i-TTL. It also has DX/FX format detection, high speed sync on the camera as well as in wireless mode and certainly a modeling light – just to check some of the boxes on the long feature list.

Introduced in 2008 this flash replaced the SB-800 from 2003. The biggest improvement is the user interface of the flash sporting a higher number of direct buttons and keys than its menu-driven precursor could offer.

The SB-900 gives up the idea of using a 5th battery as was an option with the SB-800 but has faster recycling after a full power shot nevertheless.

The SB-900 is the most advanced and capable wireless flash for Nikon: with 3 independent slave groups it offers the same range as the precursor SB-800 while being much easier to set up with dedicated buttons rather than requiring a trip through the menu system.

The smaller SB-700 can control only 2 groups as a master, and they must all be set to the same flash mode on top. Maybe even more important is the superior wireless sensor range of the SB-900 – reaching up to 46 meters outdoors (read more in the SB-700 review).

However, there’s also been a good amount of critique, mainly around 3 points.

First there is the guide number of 34 (meters): While being clearly higher than the 28 (meters) of the SB-700 mid-range flash it’s also clearly lower than previous pro flashes from Nikon with guide number of 38 since 2002 (introduced with the SB-80DX and then for SB-800). You could say that with adjustable ISO’s it doesn’t matter that much in today’s digital world where you can dial up the ISO, but that trick doesn’t work for daylight fill flash at least.

Second is the thermal cutoff which tends to be too fast at shutting down the SB-900 for heat protection (see e.g. here in this video where it’s fired next to the SB-700 flash).

And third is the fact that the first series of SB-900s had a thicker base plate on the flash foot than usual (“fat foot”). This was probably intended to help with a tighter hot shoe fit, but it for sure caused issues with other mountings, triggers etc. My own SB-900 from 2010 has a normal flash foot, exactly the same as the SB-700, so this has been changed in the meantime by Nikon.

The biggest drawback is maybe the the price – you pay about $ for an SB-900 as of October 2011. For around $ you can get the precursor SB-800 which is still highly desired today, or the new mid-range SB-700 from Nikon.

When it comes to third party flashes with master mode, there’s the Metz 58 AF-2 which is probably the closest contender in terms of feature set and depth of system integration and comes with almost $100 smaller price tag. Another very strong competitor is Nissin’s Di866, especially in the slightly improved “Mark II” version. The Sigma EF-610 DG Super completes the list but receives the least positive reviews from its users – but it’s really, really cheap!

  • guide number of 34 (meters, at 35mm) a bit below average for a pro flash
  • tends to suffer from thermal cut-off issues
  • “fat” flash foot on earlier models

Compatible Nikon Camera Bodies

The SB-900 is compatible with all Nikon DSLR cameras since 2004 (D70, D2 series, D200 or newer), but not with the old and obsolete D100 or the D1 using the first gen D-TTL. What’s more of an issue for users of analog Nikons is the lack of film-based TTL mode.

Analog Nikon photographers, except the F6, won’t be happy with the SB-900 (nor with the SB-700 in that respect), unless you use the speedlight in manual mode. Another option is the “auto” mode of the flash where the flash is metering exposure without the camera being involved, and this often works very well despite the simpler technology used.

One Response to Nikon Speedlight SB-900 Flash

    I have the SB 900 and the SB 600. The 900 did quit on me a number of times on a fashion shoot, this was immensely frustrating and for no apparent reason either, it was still cool to the touch and the number of shots were not excesive. I had a battery extended pack on the flash as well???? Shots were wicked I must say :D
