Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus PEN E-PL1 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 Olympus E-PL1 and the Olympus XZ-1. 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 measures are rounded to the nearest millimeter.

The E-PL1 can be obtained in four different colors (black, blue, yellow, white), while the XZ-1 is available in two color-versions (black, white).

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 notably smaller (13 percent) than the Olympus E-PL1. In this context, it is worth noting that neither the E-PL1 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 E-PL1 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 E-PL1 and their specifications in the Micro Four Thirds Lens Catalog.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons 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-1 was launched at a lower price than the E-PL1, despite having a lens built in. 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Olympus E-PL1 features a Four Thirds sensor and the Olympus XZ-1 a 1/1.7-inch sensor. The sensor area in the XZ-1 is 80 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 4.4. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

With 12.2MP, the E-PL1 offers a higher resolution than the XZ-1 (10.1MP), but the E-PL1 nevertheless has larger individual pixels (pixel pitch of 4.29μm versus 2.13μm for the XZ-1) due to its larger sensor. However, the XZ-1 is a somewhat more recent model (by 11 months) than the E-PL1, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.

The resolution advantage of the Olympus E-PL1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-PL1 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 Olympus XZ-1 are 18.3 x 13.8 inches or 46.5 x 35 cm for good quality, 14.7 x 11 inches or 37.2 x 28 cm for very good quality, and 12.2 x 9.2 inches or 31 x 23.3 cm for excellent quality prints.

The Olympus PEN E-PL1 has a native sensitivity range from ISO 200 to ISO 3200. The corresponding ISO settings for the Olympus XZ-1 are ISO 100 to ISO 6400 (no boost).

In terms of underlying technology, the E-PL1 is build around a CMOS sensor, while the XZ-1 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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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 E-PL1 provides substantially higher image quality than the XZ-1, with an overall score that is 20 points higher. This advantage is based on 2.7 bits higher color depth, 0.3 EV of lower dynamic range, and 2.1 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.

Note: DXO values in italics represent estimates based on sensor size and age.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (720/30p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The E-PL1 and the XZ-1 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. However, optional viewfinders – the VF-2 for the E-PL1 and the VF-2 for the XZ-1 – are available as accessories. The following table reports on some other key feature differences and similarities of the Olympus E-PL1, the Olympus XZ-1, and comparable cameras.

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 E-PL1 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. The table below provides an overview of the connectivity of the Olympus PEN E-PL1 and Olympus XZ-1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the E-PL1 and the XZ-1 have been discontinued, but can regularly be found used on ebay. The E-PL1 was replaced by the Olympus E-PL2, while the XZ-1 was followed by the Olympus XZ-2. Further information on the features and operation of the E-PL1 and XZ-1 can be found, respectively, in the Olympus E-PL1 Manual (free pdf) or the online Olympus XZ-1 Manual.

Review summary

So what is the bottom line? Is the Olympus E-PL1 better than the Olympus XZ-1 or vice versa? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Olympus PEN E-PL1:

• More detail: Offers more megapixels (12.2 vs 10.1MP) with a 10% higher linear resolution.
• Better image quality: Scores substantially higher (20 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (2.7 bits more color depth).
• Better low-light sensitivity: Requires less light for good images (2.1 stops ISO advantage).
• Faster burst: Shoots at higher frequency (3 vs 2 flaps/sec) to capture the decisive moment.
• More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
• More heavily discounted: Has been on the market for longer (launched in February 2010).

Arguments in favor of the Olympus XZ-1:

• Larger screen: Has a bigger rear LCD (3.0" vs 2.7") 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: Has an integrated lens, whereas the E-PL1 necessitates an extra lens.
• More compact: Is smaller (111x65mm vs 115x72mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the E-PL1).
• Longer lasting: Gets more shots (320 versus 290) out of a single battery charge.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Was introduced somewhat (11 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the XZ-1 emerges as the winner of the match-up (9 : 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 Olympus E-PL1 and the Olympus XZ-1 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens 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 E-PL1 or the XZ-1. 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 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 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 comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
