Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D750 and the Nikon D300? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Nikon D750 and the Nikon D300. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures are rounded to the nearest millimeter.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D300 is notably larger (5 percent) than the Nikon D750. Moreover, the D300 is markedly heavier (23 percent) than the D750. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. A larger imaging sensor (as in the D750) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (D300). You can compare the optics available in the Nikon Lens Catalog.

Concerning battery life, the D750 gets 1230 shots out of its Nikon EN-EL15 battery, while the D300 can take 1000 images on a single charge of its Nikon EN-EL3e power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The D300 was launched at a somewhat lower price (by 22 percent) than the D750, which makes it more attractive for photographers on a tight budget. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units in a sensor of the same technological generation. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Nikon D750 features a full frame sensor and the Nikon D300 an APS-C sensor. The sensor area in the D300 is 57 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

In terms of chip-set technology, the D750 uses a more advanced image processing engine (EXPEED 4) than the D300 (EXPEED), with benefits for noise reduction, color accuracy, and processing speed.

With 24.2MP, the D750 offers a higher resolution than the D300 (12.2MP), but the D750 nevertheless has larger individual pixels (pixel pitch of 5.97μm versus 5.53μm for the D300) due to its larger sensor. Moreover, the D750 is a much more recent model (by 7 years) than the D300, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The resolution advantage of the Nikon D750 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D750 for good quality output (200 dots per inch) amounts to 30.1 x 20.1 inches or 76.4 x 51 cm, for very good quality (250 dpi) 24.1 x 16.1 inches or 61.1 x 40.8 cm, and for excellent quality (300 dpi) 20.1 x 13.4 inches or 50.9 x 34 cm. The corresponding values for the Nikon D300 are 21.4 x 14.2 inches or 54.5 x 36.2 cm for good quality, 17.2 x 11.4 inches or 43.6 x 28.9 cm for very good quality, and 14.3 x 9.5 inches or 36.3 x 24.1 cm for excellent quality prints.

The Nikon D750 has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 50-51200. The corresponding ISO settings for the Nikon D300 are ISO 200 to ISO 3200, with the possibility to increase the ISO range to 100-6400.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

For many cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under review, the D750 provides substantially higher image quality than the D300, with an overall score that is 26 points higher. This advantage is based on 2.7 bits higher color depth, 2.5 EV in additional dynamic range, and 2.1 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The D750 indeed provides movie recording capabilities, while the D300 does not. The highest resolution format that the D750 can use is 1080/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The D750 and the D300 are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the D750 has a higher magnification than the one of the D300 (0.70x vs 0.63x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Nikon D750, the Nikon D300, and comparable cameras.

The Nikon D750 and the Nikon D300 both have an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

The D750 writes its imaging data to SDXC cards, while the D300 uses Compact Flash cards. The D750 features dual card slots, which can be very useful in case a memory card fails. In contrast, the D300 only has one slot.

Connectivity comparison

For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Nikon D750 and Nikon D300 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D750 offers wifi support, while the D300 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.

Both the D750 and the D300 have been discontinued, but can regularly be found used on ebay. The D300 was replaced by the Nikon D300S, while the D750 was followed by the Nikon D780. Further information on the features and operation of the D750 and D300 can be found, respectively, in the Nikon D750 Manual (free pdf) or the online Nikon D300 Manual.

Review summary

So how do things add up? Is the Nikon D750 better than the Nikon D300 or vice versa? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Nikon D750:

• More detail: Offers more megapixels (24.2 vs 12.2MP) with a 41% higher linear resolution.
• Better image quality: Scores substantially higher (26 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (2.7 bits more color depth).
• More dynamic range: Captures a larger spectrum of light and dark details (2.5 EV of extra DR).
• Better low-light sensitivity: Requires less light for good images (2.1 stops ISO advantage).
• Better jpgs: Has a more modern image processing engine (EXPEED 4 vs EXPEED).
• Broader imaging potential: Can record not only still images but also 1080/60p movies.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.63x).
• Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1229k vs 922k dots).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Less heavy: Is lighter (by 175g or 19 percent) and hence easier to carry around.
• Longer lasting: Can take more shots (1230 versus 1000) on a single battery charge.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More modern: Reflects 7 years of technical progress since the D300 launch.

Arguments in favor of the Nikon D300:

• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• More affordable: Was released into a lower priced segment (22 percent cheaper at launch).
• More heavily discounted: Has been around for much longer (launched in August 2007).

If the count of relative strengths (bullet points above) is taken as a measure, the D750 is the clear winner of the match-up (16 : 3 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

How about other alternatives? Do the specifications of the Nikon D750 and the Nikon D300 place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the D750 or the D300 perform in practice. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

Expert reviews

This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
