This review is for the Speedlight SB-910. As of the time of this review, this flash's reviews are being combined with the SB-400 and SB-700.I have owned two flash units prior to this, the

, and the

 before that. The jump from the SB-400 to the SB-600 was significant; while the SB-400 worked well in landscape, the inability to tilt the bulb to the side, as well as the lack of CLS/wireless capability, limited lighting profiles to only one or two options. Both the SB-600 and SB-910 have these options, so why bother upgrade?The SB-600 has a zoom range of 24mm-85mm, with a 14mm option with use of the wide flash adapter. The SB-910 has a zoom range of 17-200mm, and goes down to around 11mm (from what I recall) with the use of the adapter. It complements the

.User interface is THAT much better. I have not used the SB-700, 800, or 900, so I do not know the progression of the UI, but something major happened between the SB-600 and 910. The interface on the 600 was not intuitive; the manual had to be read in order for one to navigate it's functionality. For instance, two buttons had to be held down to enter the options menu to change it into a remote unit; even then, there were almost cryptic symbols and and abbreviations that had to be deciphered in order to enable that functionality. Never mind figuring out which button advanced the menu and which one changed the option. With the 910, most of its functionality can be comprehended via the LCD screen.The SB-600 is still a great addition to anyone's setup, it just needs some time to get acquainted with. Beyond the reasoning for the upgrade, a few items worth mentioning about the SB-910:Pros:1. UI is simple and easy to navigate. As stated above, the SB-600 took a bit of reading to understand how to operate. The SB-910 has a dedicated menu button, modes button, a scroll wheel for changing options, an OK button, etc., so no two finger gestures needed. There's a temperature display on the unit as well, so you know when it's about to melt. Display shows a number of different pieces of information: ISO, zoom, aperture, range... the list goes on.2. Built in wide flash adapter and bounce card. The SB-600 had the wide flash but not the bounce card. Not only that, but the SB-910 comes with a fluorescent and incandescent removable filter, as well as a diffuser.3. External ports. Behind the Nikon logo under the LEDs is an external power port. Thought it was just a decoration at first. On the side is a sync port.4. Remote/master switch. A dedicated switch that allows for easy mode change. It was done through the menu on the SB-600 and was such a hassle. It's nice to be able to make the change on the fly with the flip of a switch.5. Amazing recharge cycle. Pointing straight forward, the 910 has been able to keep up with the continuous shot modes for some time (tested up to 6fps).Cons:1. Larger/heavier than the SB-600. With the LCD screen displaying all that it can, and the flash quite a bit more powerful than the 600, it's not surprising. But the weight increase is noticeable, especially when the camera already weighs a bit without the flash on top.2. Battery drainer. I've gone through 4 sets of Eneloops in a day with this guy. It takes 4 AA batteries, so I went through a case of 16 in under 24 hours.3. Takes up a lot more space in the bag. Obviously, a larger unit would take up more space. But the case is not elongated like the SB-600. It's more of a square, and the 910 stores in the L position, not the I position like the 600 does. This is because the filters store in the area below. If not using the case, it can be stored in the I position though, and only thicker by a few millimeters.4. Not sure who's fault this is (mine, Adobe, Nikon), but all of my photos are pitch black in Lightroom. I have to run all my photos through Auto Tone once just to see the pictures, but they come out exposed properly afterwards. I'm guessing it's the TTL-BL mode. The raw photos are fine when viewed through the camera's LCD, though.5. Does not come with external power or sync cord. Would've been nice to have thrown in given the price. Jut a FYI in case anyone was curious.Overall, a nice upgrade to fill in some gaps that the SB-600 left.

NikonD700にAF-S VR-NIKKOR 70-200mmを装着と他にNIKON N AF-S NIKKOR　24-120mm 1:4G EDを入れて、しょっています。ギリギリ押し込んでいます。バッグは大は小を兼ねるを念頭に一考されたい。

ニコンD7000 + AF-S DX NIKKOR 16-85mm がすっぽり入ります。価格の割にしっかりした造りで、軽いので手軽に持ち出せます。

Lo uso quando non devo portare molta attrezzatura in giro. Ci sta un corpo macchina full frame più un obiettivo di media grandezza (Nikon d810 + Nikkor 24-120) e una GoPro e nella tasca superiore c'è spazio per uno smartphone e un portafogli. Comodissimo per estrarre velocemente la fotocamera. Dopo anni di utilizzo senza troppe attenzioni è ancora perfetto

No he notado ninguna merma exagerada de calidad. Buen producto, recomendable. Usado en una Z7 con Nikkor Z 14-30 y todo correcto.

Perfect fit, and they look great too. Missing the “NIKKOR” logo, but for the cost savings, it’s not much to quibble about.

Es un trípode muy robusto. Soporta sin problemas mi cámara, el grip y el lente Nikkor 14-24 mm. Muy recomendable.

got the third upgrade for my d800 already paired with 14-24mm 2.8 Nikkor.THE flash unit.Well built and extremely powerful but yet precise.Bought once and forgot about everything else. Thank You Amazon as usually.Recommended ?Hell YES!
