Nikon D300 vs Nikon D200: 디자인면에서 주요 차이
When comparing the Nikon D300 to the Nikon D200 one of the most obvious visible differences between the two cameras is the new large 3.0-inch LCD screen on the Nikon D300 versus the 2.5-inch screen on the Nikon D200.
The Nikon D300 features a more sculpted body design than the D200. The Mode button and the +/- Exposure Compensation button located on the front grip above the shutter release are now round and raised making them even more accessible compared to the oblong shape of the same two function buttons on the Nikon D200.
The PC sync connection socket (for studio lights) that is found on the side of the Nikon D200 has been moved on the Nikon D300 to the front right side of the camera above the 10-pin remote socket. The little plastic threaded protective connection covers (which always get lost) are gone on the D300, and have been replaced with new hinged covers that are attached by the strap eyelet to the camera body .
Other than from an ergonomic and visual design point of view there is not much that has changed in terms of the top layout of the Nikon D300 versus the Nikon D200. The new Liveview mode on the D300 is activated by turning the continuous shooting dial to the Liveview "Lv" position.

On the control buttons on the back of the Nikon D300 the icons and text are now white making them stand out more compared to the gold/dark yellow colour of the similar buttons on the D200. The Playback button on the Nikon D300 has been moved to a more convenient position on the top left corner of the camera, replacing the location of the bracketing (BKT) button on the D200. Changes to bracketing settings on the D300 is done by using the Function (Fn) button located on the front of the camera (default Custom setting f4), or can be be assigned to the depth-of-field preview button (Custom setting f5), or the AE-L/AF-L button (Custom Setting f6) The "Enter" confirmation button found towards the bottom on the Nikon D200 has been replaced with the renamed "OK" button on the Nikon D300. |
As shown below, the edge on the back thumb rest grip portion of the Nikon D300 has been raised up further towards the rear control dial making for a more comfortable feel and hold when using the dial to scroll settings.

| The Hand-held mode allows recomposing of the frame in the LCD prior to actual shooting, using the camera’s standard phase-detection autofocus system.
The second mode, called Tripod mode, is designed for precise focus accuracy with still subjects, while the camera is mounted on a tripod. The Tripod mode uses focal plane contrast autofocus. The camera normally uses phase-detection autofocus, in which the sensor splits the image from the camera lens into two using a separator lens and adjusts focus based on the separation between the two images. |

With contrast-detect autofocus, the camera analyses the data from the image sensor and then adjusts focus for the greatest contrast, on the assumption that the sharpest focus is associated with the highest level of contrast. This is similar to the auto focus method used in Coolpix compact digital cameras. Contrast-detect autofocus takes longer than phase-detection autofocus.
In tripod mode, the focus point for contrast-detect autofocus can be moved to any point in the frame using the multi selector. To focus using contrast-detect autofocus, you press the AF button on the back of the D300. The focus point will blink green and the monitor may brighten while the camera focuses. Once focus is achieved, the focus point will be displayed in green; if the camera is unable to focus, the focus point will
blink red.
