Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus E-620 and the Nikon D70? 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 Olympus E-620 and the Nikon D70 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear 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 D70 is notably larger (27 percent) than the Olympus E-620. Moreover, the D70 is markedly heavier (30 percent) than the E-620. In this context, it is worth noting that neither the E-620 nor the D70 are weather-sealed.

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 Four Thirds Lens Catalog (E-620) and the Nikon Lens Catalog (D70).

Concerning battery life, the E-620 gets 500 shots out of its Olympus BLS-1 battery, while the D70 can take 400 images on a single charge of its Nikon EN-EL3 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 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 E-620 was launched at a markedly lower price (by 30 percent) than the D70, 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 imaging sensor is a crucial determinant 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. 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Olympus E-620 features a Four Thirds sensor and the Nikon D70 an APS-C sensor. The sensor area in the D70 is 64 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.5. The sensor in the E-620 has a native 4:3 aspect ratio, while the one in the D70 offers a 3:2 aspect.

Despite having a smaller sensor, the Olympus E-620 offers a higher resolution of 12.2 megapixels, compared with 6 MP of the Nikon D70. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.29μm versus 7.85μm for the D70). However, it should be noted that the E-620 is much more recent (by 5 years) than the D70, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Olympus E-620 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-620 for good quality output (200 dots per inch) amounts to 20.2 x 15.1 inches or 51.2 x 38.4 cm, for very good quality (250 dpi) 16.1 x 12.1 inches or 41 x 30.7 cm, and for excellent quality (300 dpi) 13.4 x 10.1 inches or 34.1 x 25.6 cm. The corresponding values for the Nikon D70 are 15 x 10 inches or 38.2 x 25.4 cm for good quality, 12 x 8 inches or 30.6 x 20.3 cm for very good quality, and 10 x 6.7 inches or 25.5 x 16.9 cm for excellent quality prints.

The Olympus E-620 has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Nikon D70 are ISO 200 to ISO 1600 (no boost).

In terms of underlying technology, the E-620 is build around a CMOS sensor, while the D70 uses a CCD imager. 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 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 E-620 has a notably higher overall DXO score than the D70 (overall score 5 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.9 bits higher color depth, and 0 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.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The E-620 and the D70 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 (95%), but the viewfinder of the D70 has a higher magnification than the one of the E-620 (0.50x vs 0.48x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Olympus E-620 and Nikon D70 along with similar information for a selection of comparators.

One feature that differentiates the E-620 and the D70 is in-body image stabilization (IBIS). The E-620 reduces the risk of handshake-induced blur with all attached lenses, while the D70 offers no blur reduction with lenses that themselves do not provide optical image stabilization.

The E-620 writes its imaging data to Compact Flash or xD Picture cards, while the D70 uses Compact Flash cards. The E-620 features dual card slots, which can be very useful in case a memory card fails. In contrast, the D70 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 Olympus E-620 and Nikon D70 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the E-620 and the D70 have been discontinued, but can regularly be found used on ebay. The D70 was replaced by the Nikon D70s, while the E-620 was followed by the Olympus E-600. Further information on the features and operation of the E-620 and D70 can be found, respectively, in the Olympus E-620 Manual (free pdf) or the online Nikon D70 Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Olympus E-620 or the Nikon D70 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Olympus E-620:

• More detail: Offers more megapixels (12.2 vs 6MP) with a 40% higher linear resolution.
• Better image quality: Scores markedly higher (5 points) in the DXO overall assessment.
• Larger screen: Has a bigger rear LCD (2.7" vs 1.8") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (230k vs 130k dots).
• 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.
• Faster burst: Shoots at higher frequency (4 vs 3 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (130x94mm vs 140x111mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 158g or 23 percent) and hence easier to carry around.
• Longer lasting: Can take more shots (500 versus 400) on a single battery charge.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.0).
• 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 (30 percent cheaper at launch).
• More modern: Reflects 5 years of technical progress since the D70 launch.

Arguments in favor of the Nikon D70:

• Larger viewfinder image: Features a viewfinder with a higher magnification (0.50x vs 0.48x).
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• More heavily discounted: Has been around for much longer (launched in January 2004).

If the count of individual advantages (bullet points above) is taken as a guide, the E-620 is the clear winner of the match-up (15 : 3 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 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 Olympus E-620 and the Nikon D70 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 E-620 or the D70. 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 expert reviews 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 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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
