Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D610 and the Nikon D300S? 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

An illustration of the physical size and weight of the Nikon D610 and the Nikon D300S is provided in the side-by-side display below. 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 dimensions 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 D300S is notably larger (6 percent) than the Nikon D610. Moreover, the D300S is markedly heavier (10 percent) than the D610. 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 D610) 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 D610 gets 900 shots out of its Nikon EN-EL15 battery, while the D300S can take 950 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.

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 D300S was somewhat cheaper (by 10 percent) than the D610 at launch, but both cameras fall into the same price category. 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Nikon D610 features a full frame sensor and the Nikon D300S an APS-C sensor. The sensor area in the D300S 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 D610 uses a more advanced image processing engine (EXPEED 3) than the D300S (EXPEED), with benefits for noise reduction, color accuracy, and processing speed.

With 24.2MP, the D610 offers a higher resolution than the D300S (12.2MP), but the D610 nevertheless has larger individual pixels (pixel pitch of 5.97μm versus 5.53μm for the D300S) due to its larger sensor. Moreover, the D610 is a much more recent model (by 4 years and 2 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 pixels.

The resolution advantage of the Nikon D610 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D610 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 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 D610 has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 50-25600. The corresponding ISO settings for the Nikon D300S 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 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 review, the D610 provides substantially higher image quality than the D300S, with an overall score that is 24 points higher. This advantage is based on 2.6 bits higher color depth, 2.2 EV in additional dynamic range, and 1.9 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the D610 provides a higher video resolution than the D300S. It can shoot video footage at 1080/30p, while the D300S is limited to 720/24p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The D610 and the D300S 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 D610 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 D610, the Nikon D300S, and comparable cameras.

The Nikon D610 and the Nikon D300S 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 D610 writes its imaging data to SDXC cards, while the D300S uses Compact Flash or SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails. The D610 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 D610 and Nikon D300S and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D610 has a headphone jack, which is not present on the D300S This port makes it possible to attach external headphones and monitor the quality of sound during the recording process.

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

Both the D610 and the D300S have been discontinued, but can regularly be found used on ebay. The D300S was replaced by the Nikon D500, while the D610 does not have a direct successor. Further information on the features and operation of the D610 and D300S can be found, respectively, in the Nikon D610 Manual (free pdf) or the online Nikon D300S Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Nikon D610 and the Nikon D300S? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Nikon D610:

• More detail: Offers more megapixels (24.2 vs 12.2MP) with a 41% higher linear resolution.
• Better image quality: Scores substantially higher (24 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (2.6 bits more color depth).
• More dynamic range: Captures a larger spectrum of light and dark details (2.2 EV of extra DR).
• Better low-light sensitivity: Requires less light for good images (1.9 stops ISO advantage).
• Better jpgs: Has a more modern image processing engine (EXPEED 3 vs EXPEED).
• Better video: Provides higher definition movie capture (1080/30p vs 720/24p).
• Better sound control: Has a headphone port that enables audio monitoring while recording.
• 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.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Reflects 4 years and 2 months of technical progress since the D300S launch.

Reasons to prefer the Nikon D300S:

• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• Faster burst: Shoots at higher frequency (7 vs 6 flaps/sec) to capture the decisive moment.
• More heavily discounted: Has been around for much longer (launched in July 2009).

If the number of relative strengths (bullet points above) is taken as a guide, the D610 is the clear winner of the match-up (12 : 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 D610 and the Nikon D300S 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the D610 or the D300S. 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.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
