Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D40 and the Olympus XZ-1? 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 D40 and the Olympus XZ-1. 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.

The XZ-1 can be obtained in two different colors (black, white), while the D40 is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus XZ-1 is considerably smaller (38 percent) than the Nikon D40. In this context, it is worth noting that neither the D40 nor the XZ-1 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the XZ-1 has a lens built in, whereas the D40 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 D40 and their specifications in the Nikon Lens Catalog.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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.

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. 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 generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 D40 features an APS-C sensor and the Olympus XZ-1 a 1/1.7-inch sensor. The sensor area in the XZ-1 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 D40 has a native 3:2 aspect ratio, while the one in the XZ-1 offers a 4:3 aspect.

Despite having a smaller sensor, the XZ-1 offers a higher resolution of 10.1 megapixels, compared with 6 MP of the D40. 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 2.13μm versus 7.85μm for the D40). However, it should be noted that the XZ-1 is much more recent (by 4 years and 1 month) than the D40, 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 XZ-1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the XZ-1 for good quality output (200 dots per inch) amounts to 18.3 x 13.8 inches or 46.5 x 35 cm, for very good quality (250 dpi) 14.7 x 11 inches or 37.2 x 28 cm, and for excellent quality (300 dpi) 12.2 x 9.2 inches or 31 x 23.3 cm. The corresponding values for the Nikon D40 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 Nikon D40 has a native sensitivity range from ISO 200 to ISO 1600, which can be extended to ISO 200-3200. The corresponding ISO settings for the Olympus XZ-1 are ISO 100 to ISO 6400 (no boost).

Technology-wise, both cameras are equipped with CCD (Charged Coupled Device) 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 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 D40 provides substantially higher image quality than the XZ-1, with an overall score that is 22 points higher. This advantage is based on 2.2 bits higher color depth, 0.6 EV in additional dynamic range, and 2.3 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. The XZ-1 indeed provides for movie recording, while the D40 does not. The highest resolution format that the XZ-1 can use is 720/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the D40 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the XZ-1 relies on live view and the rear LCD for framing. That said, the XZ-1 can be equipped with an optional viewfinder – the VF-2. The adjacent table lists some of the other core features of the Nikon D40 and Olympus XZ-1 along with similar information for a selection of comparators.

The Olympus XZ-1 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 D40 writes its imaging data to SDHC cards, while the XZ-1 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.

Both the D40 and the XZ-1 have been discontinued, but can regularly be found used on ebay. The D40 was replaced by the Nikon D40X, while the XZ-1 was followed by the Olympus XZ-2. Further information on the features and operation of the D40 and XZ-1 can be found, respectively, in the Nikon D40 Manual (free pdf) or the online Olympus XZ-1 Manual.

Review summary

So how do things add up? Which of the two cameras – the Nikon D40 or the Olympus XZ-1 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Nikon D40:

• Better image quality: Scores substantially higher (22 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (2.2 bits more color depth).
• More dynamic range: Captures a larger spectrum of light and dark details (0.6 EV of extra DR).
• Better low-light sensitivity: Requires less light for good images (2.3 stops ISO advantage).
• Easier framing: Has an optical viewfinder for image composition and settings control.
• Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
• Faster burst: Shoots at higher frequency (2.5 vs 2 flaps/sec) to capture the decisive moment.
• More flexible: Can take a variety of interchangeable lenses, including specialty optics.
• Longer lasting: Can take more shots (470 versus 320) on a single battery charge.
• More heavily discounted: Has been available for much longer (launched in November 2006).

Advantages of the Olympus XZ-1:

• More detail: Has more megapixels (10.1 vs 6MP), which boosts linear resolution by 27%.
• Broader imaging potential: Can capture not only stills but also 720/30p video.
• Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (614k vs 230k dots).
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Ready to shoot: Comes with an integrated lens, while the D40 requires a separate lens.
• More compact: Is smaller (111x65mm vs 124x94mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the D40).
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• More modern: Reflects 4 years and 1 month of technical progress since the D40 launch.

If the number of relative strengths (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 D40 and the Olympus XZ-1 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 comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the D40 or the XZ-1. 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 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

Care should be taken when interpreting the review scores above, 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
