Most savvy Nikon shooters know there's an official Nikon USA import sales channel, and an enticing lower-priced "grey market." The catch: Nikon USA will simply refuse service on any products not imported by them. It's then up to the buyer to find service, and that can be very difficult, as Nikon doesn't provide most repair shops with parts. Retailers might offer their own warranty, but how to obtain service?
Here's some important tips, and a recent experience that shows how tricky this can be.
If you're in search of only the lowest price and willing to take your chance with ever needing repair, ignore the rest of this post. But know that increasingly complex cameras and lenses are more vulnerable, with sophisticated electronics, motors and plastic components.
First: how to tell which is "grey market" and legitimate US import when you buy: There's price of course. If the price is noticeably lower than most others, it's probably "grey market." And most retailers will disclose "USA Warranty" vs. "Import" in their online listings. Read the fine print carefully.
Second: Once you've got your product: Verify! Any USA import will have a 2-part Nikon USA Warranty form in the box. There's often (but not always!) a serial number beginning with the letters USxxxxx. With "grey market," sometimes the "manual" is an obviously photocopied version.
Don't forget to register with Nikon, or you'll only have the 1-year standard warranty!
Here's where it gets tricky: Want to verify a serial number from either an official or other seller (like eBay): good luck! According to Nikon, the only way to tell is to take the product in for repair. At that point, it's too late of course.
Now a tale of just how difficult this can be. I just purchased a Nikon 14-24 f/2.8 lens from a major national New York retailer, to take advantage of Nikon USA's current instant rebate promotions. (If you haven't yourself, get shopping! The rebates last through March 2015) The seller's site listed both "USA" and "import" options. When the lens arrived, the invoice clearly stated "USA" but there was no USA warranty card in the box.
I called the retailer, and was cheerily informed that, according to their serial number database, indeed I had a USA import. "Not to worry about that warranty card," the rep stated, "because Nikon often relies on the sales invoice as proof of purchase."
That's when I called Nikon, and was told they can't verify the serial number. I emailed a contact I have at Nikon, and got a quick reply requesting a scan of the invoice. A day later, I got a very apologetic call from the retailer, acknowledging a "mixup in our warehouse" and an overnight shipment of a genuine USA import.
The moral: be very careful about your import purchases. Even a normally reputable retailer may end up leaving you stranded when you need warranty coverage. And hopefully Nikon USA will make it easier for customers to verify their purchases.
Much has been said and speculated about sensor moiré in high-resolution cameras like the Nikon D800E and D810. It's an unavoidable artifact of the digital capture world, due to the interaction between finely-detailed repeating patterns in subject matter and the raster rows of modern camera sensors. It's typically an issue in architectural and fashion photography, where fabric and fine details trigger the effect.
In the endless quest for maximum resolution, Nikon has removed the anti-aliasing filter in these cameras, which helped control moiré at some loss of sharpness. Sensor moiré can't be accurately seen in preview, as the display will create its own moiré that may not actually be in the image file. And this type of moiré is different from that occurring with 4Color process images, in either scanning or prepress. So: how big a problem is it?
Here's an example of just how extreme moiré can be, in the 36 Megapixel Nikon D810. These screen grabs are a section of an image of the outdoor display panels at the beautiful new American Veterans Disabled for Life Memorial, in Washington, D.C. The site features strong horizontal black bands of varying width embedded in glass, to create tonality in the very large panels. Look what resulted once I opened up my photos on the computer:
Here's a closer view from the original file. You can see the bands of color. How bad are they?
You see the the beginning of efforts to isolate and remove the effect in Photoshop, by building paths and tight selections. Moiré is even present in the very sharp type layer. What a nightmare!
Can such an extreme case be fixed, or even prevented? Some suggest twisting the camera at a slight angle to minimize such moiré, but that's not always practical in tight compositions and the pressure of photo assignments--especially when the effect is not visible in camera.
To repair, there's many helpful tips available online, but in the end, it's a lot of work, and a compromise between maintaining detail and residual moiré. On this set of images, many such techniques were necessary; too extensive for this blog post. I'll post some useful resources in a followup.
Here's a small piece of the near-final result. Bands of color are completely eliminated, and residual moiré (slight diagonal banding in the fabric) is not objectionable across the entire image. Note the sharp text with no moiré or signs of blurring.
In the days of film, there would have been no such problem, at the price of considerably less image sharpness, ease of color enhancement, and with greater detail-robbing grain. But in this case, film would have saved a huge amount of post-production time and effort.
Indeed, all that terrific sharpness and resolution we are now capable of capturing can be both a blessing and a curse....
Thanks to a widely reported problem with oil spots repeatedly making their way onto the sensors of many D600 cameras, Nikon finally relented to pressure and has been offering a free replacement of faulty shutter mechanisms to all D600 owners (click here to read the official service advisory).
I've been a D600 user for a couple years now and have been wanting to send my camera in to get serviced, but unfortunately being my only camera body, I couldn't afford to pull it of of service for a week or more in order to get it fixed. I did observe the problem with oil spots as many have, even if they only showed up when I shot at tight apertures above F9. Despite repeated cleanings, the spots always came back and managed to be a continued annoyance (see below).
Since I recently added a new D750 to my kit for the holidays, it was finally time to send in the D600 to Nikon and get the problem fixed once and for all. Here's my report:
Nikon offers free shipping for your problem D600 to and from the service center and you can just print out a label at the above advisory link with the correct info and address. Since I live in Los Angeles and there's a Nikon Service center in town, I decided to take the camera there in person rather than dealing with shipping delays.
I dropped the camera off on December 23rd just before Christmas. The Nikon service center in LA is not big but the guy at the desk was super helpful and friendly, taking all the info needed and sending me off with a receipt and a promise to call when it was ready. Note that no warranty card is needed, Nikon is offering the free service regardless of warranty status.
Even though I brought the camera in just before Christmas, it only took 10 days to complete the work
Since it was the Christmas/New Year holidays I didn't expect a rapid turnaround but nonetheless the camera was ready to pickup on January 2rd, only 10 days later.
The camera was neatly packed in plastic wrap along with a list of work performed:
- replace shutter assembly
- checked auto focus operation
- checked bayonet mount
- checked mirror box
- checked shutter release
- clean image sensor
- firmware upgrade
- general check and clean
Note that even though they install a new shutter assembly, they don't reset the number of camera actuations back to zero, so your camera will still list the same number of shutter clicks as before, even though the shutter assembly is completely new and effectively has zero clicks.
Total time to complete repair: 10 days. Total cost $0.0. Thanks Nikon!

Even though it's only been on the market for a few months now, some users are reporting an issue with their D750 cameras that causes a dark band across the top of the image when shooting directly into a light source. The shadow seems to be caused by an autofocus sensor that protrudes too far into the mirror box, and appears to be a production flaw that only affects a limited number of cameras. Here's a good explanation of the problem over at Petapixel.com - Nikon D750 banding issue explained. Nikon has yet to make an official statement regarding this issue other than to say it is investigating.
