Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus E-1 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

The side-by-side display below illustrates the physical size and weight of the Olympus E-1 and the Olympus XZ-2. 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 (50 percent) than the Olympus E-1. It is worth mentioning in this context that the E-1 is splash and dust resistant, while the XZ-2 does not feature any corresponding weather-sealing.

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 E-1 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-1 and their specifications in the Four Thirds Lens Catalog.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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.

Convert to Imperial

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 E-1, 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 size of the imaging sensor is a crucial determinant 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Olympus E-1 features a Four Thirds sensor and the Olympus XZ-2 a 1/1.7-inch sensor. The sensor area in the XZ-2 is 81 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.

Technology-wise, the XZ-2 uses a more advanced image processing engine (TruePic VI) than the E-1 (TruePic), with benefits for noise reduction, color accuracy, and processing speed.

Despite having a smaller sensor, the XZ-2 offers a higher resolution of 11.8 megapixels, compared with 4.9 MP of the E-1. 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 1.91μm versus 6.78μm for the E-1). However, it should be noted that the XZ-2 is much more recent (by 9 years and 2 months) than the E-1, 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-2 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the XZ-2 for good quality output (200 dots per inch) amounts to 19.8 x 14.9 inches or 50.4 x 37.8 cm, for very good quality (250 dpi) 15.9 x 11.9 inches or 40.3 x 30.2 cm, and for excellent quality (300 dpi) 13.2 x 9.9 inches or 33.6 x 25.2 cm. The corresponding values for the Olympus E-1 are 12.8 x 9.6 inches or 32.5 x 24.4 cm for good quality, 10.2 x 7.7 inches or 26 x 19.5 cm for very good quality, and 8.5 x 6.4 inches or 21.7 x 16.3 cm for excellent quality prints.

The Olympus E-1 has a native sensitivity range from ISO 100 to ISO 800, which can be extended to ISO 100-3200. The corresponding ISO settings for the Olympus XZ-2 are ISO 100 to ISO 12800 (no boost).

In terms of underlying technology, the E-1 is build around a CCD sensor, while the XZ-2 uses a CMOS 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 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"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The XZ-2 indeed provides for movie recording, while the E-1 does not. The highest resolution format that the XZ-2 can use is 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the E-1 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 Olympus E-1, the Olympus XZ-2, and comparable cameras.

One feature that is present on the E-1, 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 E-1 writes its imaging data to Compact Flash or xD Picture cards, while the XZ-2 uses SDXC cards. The E-1 features dual card slots, which can be very useful in case a memory card fails. In contrast, the XZ-2 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-1 and Olympus XZ-2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Olympus E-1 (unlike the XZ-2) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the E-1 and the XZ-2 have been discontinued, but can regularly be found used on ebay. The E-1 was replaced by the Olympus E-3, while the XZ-2 does not have a direct successor. Further information on the features and operation of the E-1 and XZ-2 can be found, respectively, in the Olympus E-1 Manual (free pdf) or the online Olympus XZ-2 Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Olympus E-1 and the Olympus XZ-2? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Olympus E-1:

• Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
• Richer colors: The pixel size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
• Easier framing: Has an optical viewfinder for image composition and settings control.

If the number of relative strengths (bullet points above) is taken as a guide, the XZ-2 emerges as the winner of the match-up (16 : 13 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-1 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 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 E-1 or the XZ-2. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is where reviews by experts come in. 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.

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

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense.
