Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D810 and the Olympus E-30? 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 D810 and the Olympus E-30. 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 Olympus E-30 is notably smaller (15 percent) than the Nikon D810. Moreover, the E-30 is markedly lighter (28 percent) than the D810. It is worth mentioning in this context that the D810 is splash and dust resistant, while the E-30 does not feature any corresponding weather-sealing.

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 will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Nikon Lens Catalog (D810) and the Four Thirds Lens Catalog (E-30).

Concerning battery life, the D810 gets 1200 shots out of its Nikon EN-EL15 battery, while the E-30 can take 750 images on a single charge of its Olympus BLM-1 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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 E-30 was launched at a markedly lower price (by 61 percent) than the D810, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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. 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 D810 features a full frame sensor and the Olympus E-30 a Four Thirds sensor. The sensor area in the E-30 is 74 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.0. The sensor in the D810 has a native 3:2 aspect ratio, while the one in the E-30 offers a 4:3 aspect.

With 36.2MP, the D810 offers a higher resolution than the E-30 (12.2MP), but the D810 nevertheless has larger individual pixels (pixel pitch of 4.88μm versus 4.29μm for the E-30) due to its larger sensor. Moreover, the D810 is a much more recent model (by 5 years and 7 months) than the E-30, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the D810 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Nikon D810 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D810 for good quality output (200 dots per inch) amounts to 36.8 x 24.6 inches or 93.5 x 62.4 cm, for very good quality (250 dpi) 29.4 x 19.6 inches or 74.8 x 49.9 cm, and for excellent quality (300 dpi) 24.5 x 16.4 inches or 62.3 x 41.6 cm. The corresponding values for the Olympus E-30 are 20.2 x 15.1 inches or 51.2 x 38.4 cm for good quality, 16.1 x 12.1 inches or 41 x 30.7 cm for very good quality, and 13.4 x 10.1 inches or 34.1 x 25.6 cm for excellent quality prints.

The Nikon D810 has a native sensitivity range from ISO 64 to ISO 12800, which can be extended to ISO 32-51200. The corresponding ISO settings for the Olympus E-30 are ISO 100 to ISO 3200 (no boost).

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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 D810 provides substantially higher image quality than the E-30, with an overall score that is 42 points higher. This advantage is based on 4.4 bits higher color depth, 4.4 EV in additional dynamic range, and 2.4 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. The D810 indeed provides movie recording capabilities, while the E-30 does not. The highest resolution format that the D810 can use is 1080/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The D810 and the E-30 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 viewfinder in the D810 offers a wider field of view (100%) than the one in the E-30 (98%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the D810 has a higher magnification (0.70x vs 0.51x), 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 D810, the Olympus E-30, and comparable cameras.

One feature that differentiates the E-30 and the D810 is in-body image stabilization (IBIS). The E-30 reduces the risk of handshake-induced blur with all attached lenses, while the D810 offers no blur reduction with lenses that themselves do not provide optical image stabilization.

The Nikon D810 has 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 D810 writes its imaging data to Compact Flash or SDXC cards, while the E-30 uses Compact Flash or xD Picture cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails.

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 D810 and Olympus E-30 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D810 offers wifi support, while the E-30 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Studio photographers will appreciate that the Nikon D810 (unlike the E-30) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the D810 and the E-30 have been discontinued, but can regularly be found used on ebay. The D810 was replaced by the Nikon D850, while the E-30 does not have a direct successor. Further information on the features and operation of the D810 and E-30 can be found, respectively, in the Nikon D810 Manual (free pdf) or the online Olympus E-30 Manual.

Review summary

So how do things add up? Is the Nikon D810 better than the Olympus E-30 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Nikon D810:

• More detail: Offers more megapixels (36.2 vs 12.2MP) with a 76% higher linear resolution.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Scores substantially higher (42 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (4.4 bits more color depth).
• More dynamic range: Captures a larger spectrum of light and dark details (4.4 EV of extra DR).
• Better low-light sensitivity: Requires less light for good images (2.4 stops ISO advantage).
• Broader imaging potential: Can record not only still images but also 1080/60p movies.
• More complete view: Has a viewfinder with a larger field of view (100% vs 98%).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.51x).
• Larger screen: Has a bigger rear LCD (3.2" vs 2.7") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1229k vs 230k dots).
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Longer lasting: Can take more shots (1200 versus 750) on a single battery charge.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• More modern: Reflects 5 years and 7 months of technical progress since the E-30 launch.

Reasons to prefer the Olympus E-30:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• More compact: Is smaller (142x108mm vs 146x123mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 279g or 28 percent) and is thus easier to take along.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• More affordable: Was introduced into a lower priced category (61 percent cheaper at launch).
• More heavily discounted: Has been around for much longer (launched in November 2008).

If the count of relative strengths (bullet points above) is taken as a measure, the D810 is the clear winner of the match-up (18 : 8 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. 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 D810 and the Olympus E-30 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the D810 or the E-30. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
