Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D90 and the Olympus XZ-2? 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 D90 and the Olympus XZ-2 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 measures 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 XZ-2 is considerably smaller (46 percent) than the Nikon D90. In this context, it is worth noting that neither the D90 nor the XZ-2 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the XZ-2 has a lens built in, whereas the D90 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the D90 and their specifications in the Nikon Lens Catalog.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The XZ-2 was launched at a lower price than the D90, despite having a lens built in. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Nikon D90 features an APS-C sensor and the Olympus XZ-2 a 1/1.7-inch sensor. The sensor area in the XZ-2 is 88 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 4.4. The sensor in the D90 has a native 3:2 aspect ratio, while the one in the XZ-2 offers a 4:3 aspect.

With 12.2MP, the D90 offers a slightly higher resolution than the XZ-2 (11.8MP), but the D90 nevertheless has larger individual pixels (pixel pitch of 5.53μm versus 1.91μm for the XZ-2) due to its larger sensor. However, the XZ-2 is a much more recent model (by 4 years) than the D90, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The Nikon D90 has a native sensitivity range from ISO 200 to ISO 3200, which can be extended to ISO 200-6400. The corresponding ISO settings for the Olympus XZ-2 are ISO 100 to ISO 12800 (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 is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under review, the D90 provides substantially higher image quality than the XZ-2, with an overall score that is 24 points higher. This advantage is based on 2.3 bits higher color depth, 1.2 EV in additional dynamic range, and 2.2 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 can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the XZ-2 provides a better video resolution than the D90. It can shoot movie footage at 1080/30p, while the Nikon is limited to 720/24p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the D90 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the XZ-2 relies on live view and the rear LCD for framing. That said, the XZ-2 can be equipped with an optional viewfinder – the VF-2. The following table reports on some other key feature differences and similarities of the Nikon D90, the Olympus XZ-2, and comparable cameras.

One feature that is present on the D90, but is missing on the XZ-2 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The Olympus XZ-2 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 D90 writes its imaging data to SDHC cards, while the XZ-2 uses SDXC 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 D90 and Olympus XZ-2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the D90 and the XZ-2 have been discontinued, but can regularly be found used on ebay. The D90 was replaced by the Nikon D7000, while the XZ-2 does not have a direct successor. Further information on the features and operation of the D90 and XZ-2 can be found, respectively, in the Nikon D90 Manual (free pdf) or the online Olympus XZ-2 Manual.

Review summary

So how do things add up? Which of the two cameras – the Nikon D90 or the Olympus XZ-2 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Nikon D90:

• Better image quality: Scores substantially higher (24 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (2.3 bits more color depth).
• More dynamic range: Captures a larger spectrum of light and dark details (1.2 EV of extra DR).
• Better low-light sensitivity: Requires less light for good images (2.2 stops ISO advantage).
• Easier framing: Has an optical viewfinder for image composition and settings control.
• Easier setting verification: Features an LCD display on top to control shooting parameters.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• More flexible: Can take a variety of interchangeable lenses, including specialty optics.
• Longer lasting: Can take more shots (850 versus 340) on a single battery charge.
• More heavily discounted: Has been available for much longer (launched in August 2008).

Reasons to prefer the Olympus XZ-2:

• Better video: Provides higher definition movie capture (1080/30p vs 720/24p).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Ready to shoot: Comes with an integrated lens, while the D90 requires a separate lens.
• More compact: Is smaller (113x65mm vs 132x103mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the D90).
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 4 years of technical progress since the D90 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the match-up finishes in a tie (10 points each). 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 D90 and the Olympus XZ-2 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Travel-Zoom Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the D90 or the XZ-2. 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 where reviews by experts come in. 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.

Care should be taken when interpreting the review scores above, 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
