It brings a few new features, such as increased flash cycle times, a new flash head with a twist, as well as an all-new user interface. How well did it do?</p><p><MORE /></p><p><span style="font-size: medium;"><strong>Introduction<br /></strong></span>On July 1, 2008, Nikon announced the latest incarnation of its top-of-the-line flash, the SB900. It follows a long list of great modern flashes in the Nikon lineup, starting with the SB-24. Here the SB900 will be reviewed on the merits of its latest features, starting with its exterior appearance. This review is written with the assumption that the reader has some familiarity with shoe-mounted flashes.</p><p><span style="font-size: medium;"><strong>On the Outside</strong></span></p><p><img src="http://images.thoughtsmedia.com/resizer/thumbs/size/600/dht/auto/1217699268.usr15670.jpg" border="1" width="600" height="450" /><em>Figure Figure 1: Old vs New: SB900 on the left, and SB800 on the right.</em></p><p>The first thing that is noticed upon taking the SB900 out of the box is its size. Starting with the SB-28 Nikon has managed to shrink the flash to a size much smaller than competing brands without sacrificing power or recycle times. A smaller and lighter flash makes it easier to handle, and also to place in all kinds of weird angles with 3rd party flash brackets. The SB900 reverses all of that; I believe it is even bulkier than the old SB-26, one of the larger modern Nikon flashes. It certainly has been giving me some thought in packing my bags now!</p><p> </p><p><img src="http://images.thoughtsmedia.com/resizer/thumbs/size/600/dht/auto/1217795185.usr15670.jpg" border="1" /></p><p><em>Figure 2: Here, you can compare the sizes of the SB900 and the SB800. Note the size of the new flash head.</em><img src="http://images.thoughtsmedia.com/resizer/thumbs/size/600/dht/auto/1217794820.usr15670.jpg" border="1" /><br /><em>Figure 3: Quite the spread of accessories. From left, SB900 on the stand (AS-21), colour filter holder, diffusion dome, mini-folder containing four colour filters, and the included pouch. <br /></em></p><p>The other thing I noticed was the number of accessories that the flash comes with. In addition to the flash, the box also contains the following:</p><p><table style="background-color: #dcdcdc; border: #003300 1px solid;" border="1"><tbody><tr><td>Item</td><td>Purpose</td></tr><tr><td>Diffusion Dome (SW-13H)</td><td>Acts to diffuse the light in a omni-directional way; allows light from flash to bounce off different surfaces.</td></tr><tr><td>Colour Filter (SJ-900)</td><td>A pack of four colour filters to match the flash's light to the ambient surroundings. Two levels of tungsten and fluorescent tints are provided.</td></tr><tr><td>Filter holder (SZ-2)</td><td>Piece of clear plastic to hold the colour filters</td></tr><tr><td>Hotshoe stand (AS-21)</td><td>Another piece of plastic; this one a stand to mount the flash for remote flash purposes. Comes with tripod/stand mounting threads in plastic (!).</td></tr><tr><td>Pouch (SS-900)</td><td>Longest pouch for a hotshoe mount flash. Ever. Houses the flash and all the other accessories mentioned above.</td></tr></tbody></table></p><p>There were two disappointing things with the accessories. First, the colour filters used with the flash can communicate to the camera on what white balance to set, but only for the D3 and D700 cameras. Everyone else is out of luck. Second, the hotshoe stand's built-in mount is now machined with plastic threads. Consider this accessory to be disposable if the flash is going to be on and off a light stand or a tripod often.</p><p>A new thing is that the flash head now swivels by 180 degrees in both directions. Previously the flash head would swivel 180 to the left and only 90 degrees to the right. This allows the SB900 to fire towards the rear (to bounce light off a wall, for example) when operating without a flash bracket and in portrait orientation.</p><p><PAGE /></p><p><span style="font-size: medium;"><strong>The User Interface</strong></span></p><p><em><img src="http://images.thoughtsmedia.com/resizer/thumbs/size/600/dht/auto/1217699300.usr15670.jpg" border="1" />Figure Figure 4: The </em><em>SB900's controls have been totally revamped.</em></p><p>Looking at the back, Nikon has seen fit to revamp the user interface. The LCD is now bigger, and to me is easier to read than the one on the SB800. Gone is the d-pad that had direct control over the flash's zoom and flash power compensation; in its place is a new rotary dial (not unlike Canon's) and a soft button menu system. It works well, but sometimes for quick adjustments pertaining to flash compensation it can be faster with the older flashes to hit a button once or twice instead of having to press a soft menu button followed by twirling the dial.</p><p><img src="http://images.thoughtsmedia.com/resizer/thumbs/size/600/dht/auto/1217699516.usr15670.jpg" border="1" /></p><p><em>Figure 5: The SB900 controls up close.</em></p><p>Also new is a manual hardware switch that switches the flash on and off, as well as enabling the wireless flash system Nikon calls Creative Lighting System (CLS). No more digging through custom menus just to enable the wireless modes. A minor complaint on needing to depress the interlock button before being able to slide the switch to the wireless modes: it is a little awkward in practice, as the switch is somewhat flat and does not provide a good grip for a thumb mashed over it.</p><p>Another small point: the locking lever is stiffer and not as smooth as those on previous versions. Not a big deal, but it might get in the way if one is in a hurry.<PAGE /></p><p><span style="font-size: medium;"><strong>The SB900 In Use<br /></strong></span>Out in the field, the SB900 did not feel any different in practice to the SB800. Nikon's iTTL system by now is mature and reliable. I got good exposures in just about any situation, and for fill-light in the daytime, applying the usual flash compensation settings got the results I wanted. The ability of the flash in TTL mode is greatly determined by the camera it is attached to, since the flash's exposure is determined by the camera. Note the flash doesn't support the older DTTL.</p><p>One of the big improvements in the SB900 that was felt immediately was in the flash recycle times. I found not needing to wait for the flash ready light to come on as much after some sustained shooting. I also conducted a simple test of firing the SB900 and SB800 with the fifth battery multiple times at full power and timing how long it took for the ready light to come on. Sanyo Eneloops were used in all the tests. The SB900 consistently was ready in under 2.5 seconds; in comparison the SB800 would take another 0.4 to 0.5 seconds. In addition to the increased speed, the logistics of having to prepare batteries in sets of four are much simpler compared to that in sets of five.</p><p>The new flash head, touted by Nikon as giving greater creative control. It has zoom settings that let it cover, in FX full-frame terms, a focal length of 17mm to 200mm, a very wide range. A neat trick is that the flash now recognises whether it's attached to a DX camera or FX camera and adjusts the flash covereage accordingly. The new flash head also allows the flash to shape the light projected in the following three ways: Centre Weigted (a tight beam of light that only covers the centre of the frame), Standard (the usual beam coverage as in previous flashes), and Even (for extreme even flash coverage over the frame; best for photographing flat white walls). In theory, the new 200mm coverage setting with the new beam patterns could increase the range of the flash, thus rendering flash extenders useless for wildlife photographers, not to mention all the creative applications of shaping the light.</p><p>In practice though, the guide number of the SB900 isn't that different from the SB800. In fact, with the zoom head set to mid-range focal lengths, the SB900 has a smaller GN than the SB800. At 200mm, the SB900 has a GN of 57 metres at ISO 100, barely an increase over the SB800's 56 metre GN with the zoomhead set to 105mm at ISO 100.</p><p>As for shaping the light, there are some problems with the concept. Firstly, to engage the feature that does that one needs to delve into the custom function to set a light pattern of either Centre Weighted, Standard, or Even. If you were in a situation where changing the light pattern was needed every few minutes, it would grow tiresome very quickly.</p><p>The second thing is that, at the heart of it all, it seems that all that this accomplishes is to move the flash head's zoom setting a little bit forward or backward. Basically it is the same sort of thing one can get with a little nudge of the manual zoom feature. Setting a beam pattern in this manner will be more useful to those in event and wedding photography wielding a medium zoom with focal lengths going from wide angle to telephoto in seconds (as setting a beam pattern is less annoying than constantly mucking around with the manual zoom), but Nikon is promoting the new feature in more measured photosoots as well, such as portrait photography, both on-camera or off-camera.</p><p><img src="http://images.thoughtsmedia.com/resizer/thumbs/size/600/dht/auto/1217795212.usr15670.jpg" border="1" /></p><p><img src="http://images.thoughtsmedia.com/resizer/thumbs/size/600/dht/auto/1217795204.usr15670.jpg" border="1" /><em>Figure Figure 6: The first row of photos, from left to right, show beam patterns of Centre Weighted, Standard, and Even respectively with the flash head set to 50mm DX coverage. The second row of photos, from left to right, show the flash head to 35mm DX, 50mm DX, and 70mm DX respectively with the beam pattern set to Standard. </em></p><p>As the photos show, the coverage difference is not too great. In fact, using the zoom head manually will yield a greater control of the beam pattern, since this allows manual tuning of how tight or wide a beam is desired.</p><p>Final note: In the Centre Weighted beam pattern, the flash will not set a zoom head position to cover narrower than 135mm; conversely, in the Even beam pattern, the flash will not set a zoom head to cover wider than 24mm. All-in-all, this particular feature feels very much like a gimmick.</p><p><span style="font-size: medium;"><strong>Conclusion<br /></strong></span>At the end of it, the SB900 is indeed a capable flash, with even better recycle times and packing plenty of power for a hotshoe flash. The problem, however, is that compared to the SB800, it offers just two new features I consider great, as well as one that is minor at best and gimmicky at worst. All this comes at the expense of a flash that has dramatically increased in size. There's an unsatisfied feeling overall, like that of getting totally stuffed with a meal yet not quite fully satiated.</p><p>With the SB800 still available, and for much less in many countries, it represents the SB900's greatest weakness; why get a bigger, heavier and more expensive flash when a cheaper one that is almost as good is still around? If you can live without the two main improvements of faster recycle times (the SB800 still is no slouch) and the revamped UI, grab the SB800 before they go out of stock. Only if you're certain you need the improvements the SB900 has should you purchase it. As of this article's writing, the SB900 is not quite the must-have flash for all Nikon SLR users. Perhaps there will be additional improvements to the flash in future firmware updates, or drops in the pricing as it gets discounted. For now, it is quite close between the SB800 and SB900, with the SB900 favourable for more extreme or specific shooting situations.</p><p><em>Lee Yuan Sheng has been involved in photography since 12, starting with his father's Olympus OM-1.
