Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D2H and the Sony Alpha SLT-A68? 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 D2H and the Sony A68 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 size 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 Sony A68 is considerably smaller (37 percent) than the Nikon D2H. Moreover, the A68 is substantially lighter (43 percent) than the D2H. It is worth mentioning in this context that the D2H is splash and dust resistant, while the A68 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the D2H gets 2900 shots out of its Nikon EN-EL4a battery, while the A68 can take 540 images on a single charge of its Sony NP-FM500H power pack. As can be seen in the images above, the D2H has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. In order to provide similar functionality for the A68, there are third party battery grips available as optional accessories (see here on ebay).

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

The price is, of course, an important factor in any camera decision. 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 A68 was launched at a markedly lower price (by 80 percent) than the D2H, 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 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the A68 is 2 percent bigger. They nevertheless have the same format factor of 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 24MP, the A68 offers a higher resolution than the D2H (4MP), but the A68 has smaller individual pixels (pixel pitch of 3.91μm versus 9.50μm for the D2H). Yet, the A68 is a much more recent model (by 12 years and 3 months) than the D2H, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Sony A68 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A68 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Nikon D2H are 12.3 x 8.2 inches or 31.3 x 20.7 cm for good quality, 9.9 x 6.5 inches or 25 x 16.6 cm for very good quality, and 8.2 x 5.4 inches or 20.9 x 13.8 cm for excellent quality prints.

The Nikon D2H has a native sensitivity range from ISO 200 to ISO 1600, which can be extended to ISO 200-6400. The corresponding ISO settings for the Sony Alpha SLT-A68 are ISO 100 to ISO 25600 (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.

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 A68 offers substantially better image quality than the D2H (overall score 39 points higher). The advantage is based on 5.2 bits higher color depth, 3.5 EV in additional dynamic range, and 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 A68 indeed provides for movie recording, while the D2H does not. The highest resolution format that the A68 can use is 1080/60i.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A68 has an electronic viewfinder (1440k dots), while the D2H has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinders of both cameras offer the same field of view (100%), as well as the same magnification (0.57x). The adjacent table lists some of the other core features of the Nikon D2H and Sony A68 along with similar information for a selection of comparators.

One feature that differentiates the A68 and the D2H is in-body image stabilization (IBIS). The A68 reduces the risk of handshake-induced blur with all attached lenses, while the D2H offers no blur reduction with lenses that themselves do not provide optical image stabilization.

The D2H writes its imaging data to Compact Flash cards, while the A68 uses SDXC or Memory Stick PRO Duo 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 D2H and Sony Alpha SLT-A68 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Nikon D2H (unlike the A68) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the D2H and the A68 have been discontinued, but can regularly be found used on ebay. The D2H was replaced by the Nikon D2Hs, while the A68 does not have a direct successor. Further information on the features and operation of the D2H and A68 can be found, respectively, in the Nikon D2H Manual (free pdf) or the online Sony A68 Manual.

Review summary

So what conclusions can be drawn? Is the Nikon D2H better than the Sony A68 or vice versa? The listing below highlights the relative strengths of the two models.

Advantages of the Nikon D2H:

• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• Longer lasting: Can take more shots (2900 versus 540) on a single battery charge.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• More heavily discounted: Has been available for much longer (launched in July 2003).

Arguments in favor of the Sony Alpha SLT-A68:

• More detail: Has more megapixels (24 vs 4MP), which boosts linear resolution by 144%.
• Better image quality: Scores substantially higher (39 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (5.2 bits more color depth).
• More dynamic range: Captures a broader range of light and dark details (3.5 EV of extra DR).
• Better low-light sensitivity: Can shoot in dim conditions (1 stops ISO advantage).
• Broader imaging potential: Can capture not only stills but also 1080/60i video.
• More framing info: Has an electronic viewfinder that displays shooting data.
• Larger screen: Has a bigger rear LCD (2.7" vs 2.5") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (460k vs 211k dots).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• More compact: Is smaller (143x104mm vs 158x150mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 460g or 43 percent) and is thus easier to take along.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• More affordable: Was introduced into a lower priced category (80 percent cheaper at launch).
• More modern: Reflects 12 years and 3 months of technical progress since the D2H launch.

If the number of relative strengths (bullet points above) is taken as a guide, the A68 is the clear winner of the contest (16 : 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 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 D2H and the Sony A68 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 D2H and the A68 in practical situations. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

Expert reviews

This is why expert reviews 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.

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. 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, please note that some of the review sites have changed their methodology and reporting over time.
