Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon Z30 and the Olympus E-510? 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 Z30 and the Olympus E-510 are illustrated 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 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 Olympus E-510 is notably larger (32 percent) than the Nikon Z30. Moreover, the E-510 is markedly heavier (33 percent) than the Z30. It is worth mentioning in this context that the Z30 is splash and dust resistant, while the E-510 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 Z30 gets 330 shots out of its Nikon EN-EL25 battery, while the E-510 can take 750 images on a single charge of its Olympus BLM-1 power pack. The power pack in the Z30 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

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.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Z30 was launched at a somewhat lower price (by 11 percent) than the E-510, which makes it more attractive for photographers on a tight budget. 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.

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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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 Z30 features an APS-C sensor and the Olympus E-510 a Four Thirds sensor. The sensor area in the E-510 is 39 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.0. The sensor in the Z30 has a native 3:2 aspect ratio, while the one in the E-510 offers a 4:3 aspect.

With 20.7MP, the Z30 offers a higher resolution than the E-510 (10MP), but the Z30 has smaller individual pixels (pixel pitch of 4.22μm versus 4.74μm for the E-510). However, the Z30 is a much more recent model (by 15 years and 3 months) than the E-510, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the Z30 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Nikon Z30 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Z30 for good quality output (200 dots per inch) amounts to 27.8 x 18.6 inches or 70.7 x 47.1 cm, for very good quality (250 dpi) 22.3 x 14.8 inches or 56.6 x 37.7 cm, and for excellent quality (300 dpi) 18.6 x 12.4 inches or 47.1 x 31.4 cm. The corresponding values for the Olympus E-510 are 18.2 x 13.7 inches or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inches or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inches or 30.9 x 23.2 cm for excellent quality prints.

The Z30 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Nikon Z30 has a native sensitivity range from ISO 100 to ISO 51200, which can be extended to ISO 100-204800. The corresponding ISO settings for the Olympus E-510 are ISO 100 to ISO 1600 (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. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. The Z30 indeed provides movie recording capabilities, while the E-510 does not. The highest resolution format that the Z30 can use is 4K/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the E-510 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the Z30 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Nikon Z30 and Olympus E-510 along with similar information for a selection of comparators.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The Z30 has a touchscreen, while the E-510 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the Z30 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Nikon Z30 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 Z30 writes its imaging data to SDXC cards, while the E-510 uses Compact Flash or xD Picture cards. The E-510 features dual card slots, which can be very useful in case a memory card fails. In contrast, the Z30 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 Nikon Z30 and Olympus E-510 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the Z30 offers wifi support, while the E-510 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

The Z30 is a recent model that features in the current product line-up of Nikon. In contrast, the E-510 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the E-510 was succeeded by the Olympus E-520. Further information on the features and operation of the Z30 and E-510 can be found, respectively, in the Nikon Z30 Manual (free pdf) or the online Olympus E-510 Manual.

Review summary

So what is the bottom line? Is the Nikon Z30 better than the Olympus E-510 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Nikon Z30:

• More detail: Offers more megapixels (20.7 vs 10MP) with a 47% higher linear resolution.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Features a larger and more technologically advanced imaging sensor.

Arguments in favor of the Olympus E-510:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Easier framing: Has an optical viewfinder for image composition and settings control.
• Longer lasting: Gets more shots (750 versus 330) out of a single battery charge.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More heavily discounted: Has been around for much longer (launched in March 2007).

If the count of individual advantages (bullet points above) is taken as a guide, the Z30 is the clear winner of the match-up (26 : 6 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 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 Z30 and the Olympus E-510 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR Camera listings 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 says little about, for example, the shooting experience and imaging performance of the Z30 and the E-510 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 adjacent summary-table relays the overall verdicts of several of the most popular 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. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
