Nikon D300S vs Df

The Nikon D300S and the Nikon Df are two enthusiast cameras that were officially introduced, respectively, in July 2009 and November 2013. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (D300S) and a full frame (Df) sensor. The D300S has a resolution of 12.2 megapixels, whereas the Df provides 16.2 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D300S and the Nikon Df? 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 physical size and weight of the Nikon D300S and the Nikon Df are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.

The Df can be obtained in two different colors (black, silver), while the D300S is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon Df is notably smaller (6 percent) than the Nikon D300S. Moreover, the Df is markedly lighter (19 percent) than the D300S. 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 Df) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (D300S). You can compare the optics available in the Nikon Lens Catalog.

Concerning battery life, the D300S gets 950 shots out of its Nikon EN-EL3e battery, while the Df can take 1400 images on a single charge of its Nikon EN-EL14 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

Any camera decision will obviously take relative prices into account. 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 D300S was launched at a markedly lower price (by 35 percent) than the Df, which puts it into a different market segment. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

The size of the imaging sensor is a crucial determinant of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels in a sensor of the same technological generation. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the background. On the downside, larger sensors are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Nikon D300S features an APS-C sensor and the Nikon Df a full frame sensor. The sensor area in the Df is 131 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Technology-wise, the Df uses a more advanced image processing engine (EXPEED 3) than the D300S (EXPEED), with benefits for noise reduction, color accuracy, and processing speed.

With 16.2MP, the Df offers a higher resolution than the D300S (12.2MP), but the Df nevertheless has larger individual pixels (pixel pitch of 7.29μm versus 5.53μm for the D300S) due to its larger sensor. Moreover, the Df is a much more recent model (by 4 years and 3 months) than the D300S, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Nikon Df implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Df for good quality output (200 dots per inch) amounts to 24.6 x 16.4 inches or 62.6 x 41.7 cm, for very good quality (250 dpi) 19.7 x 13.1 inches or 50.1 x 33.3 cm, and for excellent quality (300 dpi) 16.4 x 10.9 inches or 41.7 x 27.8 cm. The corresponding values for the Nikon D300S 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 D300S has a native sensitivity range from ISO 200 to ISO 3200, which can be extended to ISO 100-6400. The corresponding ISO settings for the Nikon Df are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 50-204800.

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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under consideration, the Df offers substantially better image quality than the D300S (overall score 19 points higher). The advantage is based on 2.1 bits higher color depth, 0.9 EV in additional dynamic range, and 2.1 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. The D300S indeed provides movie recording capabilities, while the Df does not. The highest resolution format that the D300S can use is 720/24p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The D300S and the Df 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 Df has a higher magnification than the one of the D300S (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 D300S, the Nikon Df, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The D300S has one, while the Df does not. While the built-in flash of the D300S is not very powerful, it can at times be useful as a fill-in light.

The Nikon D300S and the Nikon Df 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 D300S writes its imaging data to Compact Flash or SDXC cards, while the Df uses SDXC cards. The D300S features dual card slots, which can be very useful in case a memory card fails. In contrast, the Df only has one slot. The Df supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the D300S cannot take advantage of Ultra High Speed SD cards.

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 D300S and Nikon Df and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

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

Both the D300S and the Df have been discontinued, but can regularly be found used on ebay. The D300S was replaced by the Nikon D500, while the Df does not have a direct successor. Further information on the features and operation of the D300S and Df can be found, respectively, in the Nikon D300S Manual (free pdf) or the online Nikon Df Manual.

Review summary

So how do things add up? Is the Nikon D300S better than the Nikon Df or vice versa? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Nikon D300S:

• Broader imaging potential: Can record not only still images but also 720/24p movies.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• Faster burst: Shoots at higher frequency (7 vs 5.5 flaps/sec) to capture the decisive moment.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More affordable: Was introduced into a lower priced category (35 percent cheaper at launch).
• More heavily discounted: Has been available for much longer (launched in July 2009).

Reasons to prefer the Nikon Df:

• More detail: Has more megapixels (16.2 vs 12.2MP), which boosts linear resolution by 15%.
• Better image quality: Scores substantially higher (19 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (2.1 bits more color depth).
• More dynamic range: Captures a broader range of light and dark details (0.9 EV of extra DR).
• Better low-light sensitivity: Can shoot in dim conditions (2.1 stops ISO advantage).
• Better jpgs: Has a more modern image processing engine (EXPEED 3 vs EXPEED).
• 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.
• Less heavy: Has a lower weight (by 178g or 19 percent) and is thus easier to take along.
• Longer lasting: Gets more shots (1400 versus 950) out of a single battery charge.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Reflects 4 years and 3 months of technical progress since the D300S launch.

If the count of individual advantages (bullet points above) is taken as a guide, the Df is the clear winner of the contest (12 : 7 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 D300S and the Nikon Df 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 comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the D300S and the Df in practical situations. 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
