Now reading: Nikon D Review 14 comments. Previous 1 Introduction. Nikon D Key Features Higher resolution sensor Like the D before it, the Nikon D sports an AF-S lens mount, which lacks autofocus support for the older AF lenses whose focus mechanisms were driven from the camera.
These lenses have what looks like a little screwdriver slot on their mounting flange that couples with a protruding, screwdriver-looking shaft on the camera body. A motor in the camera body is thus required to drive the lens mechanics to adjust focus. More recent Nikkor lenses have motors built into the lens body, which tend to be both faster and quieter than the old-style drive system, as well as allowing the camera body to be lighter, smaller and cheaper.
CPU-equipped lenses lacking built-in focus motors can be used in manual focus mode, and type G or D lens types will also support full 3D color matrix metering for more accurate exposures, particularly when flash is being used.
You can tell CPU-equipped lenses by the set of five electrical contacts arrayed on the side of the lens flange. Focus and Exposure. The Nikon D shares the same Multi-CAM phase-detection autofocus sensor module that's previously appeared in the D and D, among others. The Multi-CAM module offers 11 focusing points, of which the center point is a cross-type sensor.
While the AF sensor itself is unchanged, Nikon has updated the viewfinder point display. In the D, the approximate AF point locations were indicated with dense black marks in the viewfinder.
For the Nikon D, these have been replaced with much fainter markings, illuminated by single LEDs. One further change to the viewfinder display, perhaps related to this change, is that the Nikon D lacks the on-demand grid display function from the D Operation of the Auto exposure mode has been changed, however, as the D will now automatically pick a scene type from among the six scene modes when first entering Auto mode.
As with the D and D before it, the shutter mechanism included in the Nikon D is rated at a lifetime of , cycles. The flash itself is the same as that used in the D, and is fairly powerful, with a guide number of 12 meters or 39 feet at ISO in auto mode, extending slightly to 13 meters 43 feet in Manual mode.
Dust control. The Nikon D includes the company's three-pronged strategy for controlling dust on the image sensor. Nikon's Dust Reduction System uses vibration to shake dust off the low-pass filter, whereupon the mirror chamber design causes an air flow with each shutter release that carries dust to a capture receptacle.
The final part of the approach requires the optional Nikon Capture NX 2 software, and involves creation of a reference photo that is used to identify the location of stubborn dust specks. These can then be replaced by automatically interpolating data from areas of the image adjacent to the dust. Perhaps the main area in which Nikon's earlier D lags behind its current-day competition is in the absence of either Live View or movie capture capabilities.
Both functions still prove somewhat divisive, with some photographers finding them an unnecessary, little-used distraction, and others greatly enjoying the ability to frame images in the same manner as they would with a compact camera, or to shoot movies with the same versatility in terms of both interchangeable lenses and shallow depth of field effect that SLR photography makes possible in still imaging, something most dedicated camcorders can't offer.
The absence of video is probably the lesser evil, as arguably most video-capable DSLRs haven't proven ready for consumers, thanks to the absence of continuous autofocus capabilities.
However, there's little question that with a generation of photographers now strongly accustomed to framing images on their LCD, Live View is simply a must-have feature even in a consumer digital SLR these days. The Nikon D corrects both oversights, with numerous changes that combine to provide a genuinely useful Live View function, and a Movie mode with impressive High-Definition capabilities, although still with one important drawback versus shooting with a dedicated camcorder.
As previously noted, the Nikon D now includes a dedicated switch on its rear panel that allows Live View shooting to be initiated without entering the camera's menu system. Autofocus starts immediately when the mode is entered, and continues until the shutter button is half-pressed. At this point, focus is locked until the shutter button is released, or half-pressed a second time to resume continuous AF operation. Perhaps even more unusually, full-time autofocus is also available during video capture, albeit at the expense of clearly audible focusing noise being picked up on the movie's audio track.
This is perhaps less of an issue for consumer videographers, who may be willing to put up with the noise in return for the ability to focus during movie capture. The ability to pull focus manually isn't an easy art to learn, after all. It's certainly something to be aware of, though, and with no external microphone connectivity, there's no way to isolate the AF noise, short of recording sound on a separate device and replacing the audio track in post-processing.
There's a slight catch, in that for Full HD, the Nikon D can only record at a rate of 24 frames per second Whether the reduced frame rate at full resolution will prove a drawback will depend on your intended use for the video. The only other resolution available is x at 24 fps Each video clip has a maximum length of ten minutes, and the Nikon D does provide for basic in-camera editing of videos, with the ability to trim unwanted content from both the start and end of each clip.
The Nikon D's internal microphone is monaural, and with no external microphone connectivity, there's again no way to capture stereo audio without swapping the audio for that from an external device in post processing.
Movie capture is started and stopped with a new dedicated Movie Shutter button, located in the center of the Live View switch on the rear panel. With the addition of movie recording to the D, Nikon has dropped the stop-motion movie function that was found in the D Guide mode.
The Nikon D further builds on the user friendly Guide mode from the D, which is accessed from the Guide Mode position on the Mode dial.
When in the Shoot menu, the photographer is asked a number of questions, and the Nikon D then offers guidance on what to set -- and importantly, why each suggestion is being made. A helpful change from the D's Guide mode is the addition of reference photos that demonstrate the effect of settings being applied.
For example, as shown in the screenshot left , when the Guide mode recommends shutter adjustment, it also offers an image of a child kicking a football as an example of the adjustment's effect. As the shutter speed is changed, the reference photo is updated, showing the motion blur at slower shutter speeds, and a sharper image at faster shutter speeds. For aperture adjustment, similar images are available, with the level of background blur changing as the aperture value is adjusted.
Another change to the Guide mode is that, when the user has stepped through the process of answering questions and adjusting their setup per the camera's recommendations, the Nikon D will now ask whether the user wants to shoot a still image using the optical viewfinder or Live View functions, or capture a video.
Depending on the answer, the camera will be automatically placed in the correct mode. Refreshed GUI. This animation shows the difference between the menu styling of last year's Nikon D, and that of the new D Note that the camera model number is identified in the 'Playback folder' field. While the remainder of the menu system retains the same basic layout as in the D, the visual styling of the menus has also been updated. It's a relatively subtle change, but the net result is that the menu system feels cleaner and more modern.
In-camera editing. As with the D, the Nikon D offers a Retouch menu that lets users tweak images to their tastes after capture. Compared to that from the D, the Nikon D's Retouch menu offers several new functions -- straighten, distortion control, fisheye, and perspective control.
As the names suggest, these all correct for or intentionally apply distortions to images. The straighten function corrects for tilted horizons, while perspective control fixes converging vertical lines, such as you'd expect when tilting the camera upwards to fit a tall building into the frame. The Nikon D also retains the D's ability to process RAW files in-camera, and retains Retouch functions such as trimming, color balance, and red-eye correction, as well as the miniature, filter, and monochrome effects from the D Like the D before it, the Nikon D offers not only a D-Lighting function that adjusts shadows, highlights, and contrast taking into account the presence of human faces , to provide a fill-flash-like effect after image capture through the Retouch menu, but supplements this with the company's Active D-Lighting function.
Active D-Lighting, which debuted on the D3 and D, is applied to images at the time of capture. In the D can be enabled or disabled, but there's no manual control over the strength of the effect, which was also true in the D The Nikon D also includes Nikon's Picture Control System, which allows control of sharpening, contrast, brightness, saturation and hue.
Picture Control presets include Standard, Neutral, Vivid, Monochrome, Portrait, and Landscape, and each can be fine-tuned to the user's preferences.
Storage and battery. No vertical battery grip is available for the Nikon D Live View. The Nikon D's Live View mode helped me get a closeup of these colorful fall leaves, which were well above my head. An articulated LCD would've been helpful, though looking at the LCD from this angle made it hard to frame my subject, and it took five attempts to get a composition I was happy with. With an intuitive control layout that's very similar to that of the D, I felt quite at home shooting with the Nikon D While it's about par for the course among smaller, consumer DSLR bodies, I did find myself wishing that the D's grip were just slightly deeper.
With my large hands, it was just a little tiring shooting single-handed, placing more of the weight on my fingertips than is the case with the larger grips on other DSLRs. I'm especially a fan of the Function button on the left-hand side of the Nikon D's flash housing, which I configured to provide quick access to ISO sensitivity adjustments without needing to enter the menu system.
Likewise, the new release mode switch makes it easy to jump back and forth between single and burst shooting, as photo opportunities present themselves. The new Live View switch with its central movie record button is also a great design -- unlikely to be accidentally bumped, but perfectly positioned for your thumb to quickly launch Live View mode, and to start or stop movie capture with a minimum of handling noise or camera shake.
It's a shame that the LCD panel can't be tilted or swivelled, though, as this robs the Live View function of a little versatility. For example, shooting pictures of fall leaves with the Nikon D held well above my head, I found it rather difficult to see my precise framing, as I was having to look at the LCD from an extreme angle.
I still got the shot I wanted, but it took me five attempts to get the framing right. High ISO. On a sunny day in Knoxville, Tennessee, there weren't too many opportunities to shoot at high sensitivity, but this ISO 3, shot of a chandelier in a shady lobby shows that the standard ISO range is useful indeed.
I'm not the most active of movie shooters, but I did appreciate the ability to record at Full HD resolution. For videographers who are adept at pulling focus manually, or who don't mind the limitations of autofocus in terms of drive noise being clearly audible in the captured video, the Nikon D can prove a useful alternative to bringing both a still camera and a camcorder on every trip.
The Nikon D's contrast detection AF is certainly not as fast as phase detection, but it's definitely at the point where I felt it was useful for static or slowly moving subjects. My fall leaf photo was taken on a fairly breezy day, but the Nikon D still managed to lock AF in between gusts and capture a well-focused image without issue.
