Nikon D300 Review
The D300 is Nikon's most advanced non-full frame digital SLR. This is a professional grade 12 megapixels camera with high-speed continuous shooting capabilities and very sophisticated focusing and metering systems.
The Nikon D300 caters to advanced photographers by providing extensive control and customization of its interface and behavior. External lighting, including Nikon's famous speedlights, can be controlled both wired and wireless directly from the camera.
This review takes a close look at the D300's features, ergonomics, usability, image quality, performance and photographic controls. As Nikon's number two DSLR, just behind the full-frame D3, the D300 has the following major features:

Suitability - What is it good for?
The Nikon D300 is suitable for every type of photographic subject and is one of the most versatile DSLRs around. Combining its high-resolution sensor and high-speed continuous shooting with 3D tracking focus means that it covers photographic subjects from landscapes to action. The versatility of the Nikon D300 is further ensured by its compatibility with Nikon lenses and compatibility with Nikon's creative lighting system.
For specific photographic subjects, lens versatility is quite important. The Nikon lens lineup covers a wide variety of focal-lengths from the ultra-wide to the super telephoto. Most 3rd party manufacturers produce lenses for Nikon mounts too. With Nikon, image stabilization is provided by VR (Vibration Reduction) lenses which are available in some, mostly telephoto, lenses.
The Nikon D300 is larger and heavier than most DSLR cameras. This, plus its weather-sealed body, makes it more suitable for rougher environments. Conversely, its bulk is more noticeable and less discrete, plus there is bright yellow writing on the strap. This is somewhat a disadvantage for street and candid photography.
Capability - What can it do?
As noted in the introduction, the Nikon D300 has everything expected from a DSLR with an impressive amount of customization. Headline features include a built-in dust-reduction mechanism, a weatherproof body, high-speed continuous drive, a 51-point auto focus system and multiple options for RAW image formats. High speed continuous drive can shoot at 6 FPS or less without the optional battery grip, or at 8 FPS with the grip.
The Nikon D300's power-switch has 3 positions: Off, On and illuminate. The illuminate position is used to light up the top LCD, unless the option to have it permanently lit is enabled. The other two positions are self-explanatory but note that, even when the camera is off, the D300 shows how many images can still fit into the memory card at the currently set quality, resolution and file-format. This is great because you can tell if you have a card inserted without effort.
The shutter-release on this DSLR is a standard 2-stage release with a very soft halfway point. By default, pressing the shutter-release halfway locks focus and exposure. There are options to disable exposure and focus locking independently. There is a dedicated AF-ON button which can be used to lock exposure before pressing the shutter-release. There is also a combined AE-L/AF-L button which can be set to one of 13 functions, including locking exposure, locking flash metering and locking focus. AEL appears in the viewfinder whenever exposure is locked, regardless of the mechanism. This allows to confirm which behavior is active.
Exposure modes on the Nikon D300 are controlled by a modeless button. Instead of the usual mode-dial, the D300 uses a Mode button in combination with the rear command dial to select between the four ubiquitous exposure modes. These modes are: program (P), shutter-priority (S), aperture-priority (A) and full manual (M) mode. Notably absent from these mode-dial are scene modes which frequently control the camera in mysterious ways. In Manual mode, the shutter-speed selection includes a Bulb mode that keeps the shutter open as long as the shutter-release is pressed.
On the camera's rear, surrounding the AE-L/AF-L button, is the metering selection switch. While there are only three positions to this switch, the D300 has sophisticated control over metering. Matrix metering mode uses 1005 pixels to meter the entire scene. Spot metering mode uses 2% of the frame to meter for 18% gray. The center-weight metering mode uses the entire frame with 75% emphasis on the centerCustomizable between 4% and 9% using a 6mm, 8mm, 10mm or 13mm metering circle but it can be configured as average metering instead.
The Nikon D300 has detailed control over white-balance including automatic white-balance, preset white-balanceIncandescent, Fluorescent, Sunlight, Flash, Cloudy and Shade., manual white-balance and color-temperature. All white-balance options can be fine-tuned in 13-steps from blue to amber and magenta to green. Curiously, even Kelvin white-balance can be adjusted, meaning that the chosen color temperature is not necessarily accurate. Manual white-balance can be saved in one of 4 memory slots with a reference thumbnail to help remember which one is which. It seems obvious to put a thumbnail there, yet the Nikon D300 is the first camera we have seen do it. This is the kind of detail which Nikon puts in their cameras.
Exposure compensation can be adjusted in 1/2 or 1/3 EV increments using the exposure compensation button combined with the command dial. The range of exposure compensation is -5 to +5. The Nikon D300 can bracket exposure for 3, 5, 7 or 9 frames, with increments between 1/3 and 1 EV. Both the wide exposure compensation range and large bracket make the D300 a fantastic camera to form HDR images with.
This DSLR supports the standard drive modesSingle, continuous and self-timer., live-view, mirror lock-up and multiple exposure. The self-timer is customizable with possible 2s, 5s, 10s and 20s delay. Mirror lock-up requires one press of the shutter-release to raise the mirror and one to take the picture. Note that this is not ideal without a remote trigger because pressing the shutter-release can cause more vibrations than the mirror itself. Multiple-exposure can combine between 2 and 9 images with or without automatic exposure adjustment.
In continuous drive mode, the Nikon can shoot up to 100 JPEG images at 6 FPS or more. To get above 6 FPS, up to 8 FPS actually, you must use the optional battery-grip. There is a high-speed continuous drive mode which shoots at the maximum rate and a low-speed continuous shooting mode which shoots at between 1 and 7 FPS, depending on a custom-setting and, in the case of 7 FPS, whether the grip is being used or not.
Unfortunately, since drive-mode selection is modal via a dial, drive modes cannot be reset by the camera. Other cameras usually reset their long self-timer after each use. This would avoid the common mistake of forgetting to reset the long self-timer.
The Nikon D300 supports JPEG, TIFF and RAW images. JPEG images are available in 3 quality levels. TIFF files are always saved as 8-bit files which unfortunately make them only marginally better than JPEG files. Ideally, a DSLR should support losslessly compressed 16-bit TIFF files. RAW on this digital SLR is very flexible. There is the choice of uncompressed, compressed or losslessly compressed, plus the choice between 12-bit and 14-bit files. While 14-bit files are better because of higher precision, they slow down the D300's continuous shooting to a maximum of 2.5 FPS.
The image sensor is mounted on a moving plate which serves to shake off dust, reducing its accumulation. While we have not measured its efficiency, these systems are generally not 100% effective and the only remove the lightest of dust-particles. Any significantly stuck particle requires manual cleaning.
