Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus E-1 and the Sony Alpha NEX-3? 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 Sony NEX-3. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.

The NEX-3 can be obtained in three different colors (black, silver, red), while the E-1 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 Sony NEX-3 is considerably smaller (51 percent) than the Olympus E-1. Moreover, the NEX-3 is substantially lighter (60 percent) than the E-1. It is worth mentioning in this context that the E-1 is splash and dust resistant, while the NEX-3 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Four Thirds Lens Catalog (E-1) and the Sony E-Mount Lens Catalog (NEX-3). Mirrorless cameras, such as the NEX-3, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.

Concerning battery life, the E-1 gets 750 shots out of its Olympus BLM-1 battery, while the NEX-3 can take 330 images on a single charge of its Sony NP-FW50 power pack.

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.

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. The NEX-3 was launched at a markedly lower price (by 65 percent) than the E-1, which puts it into a different market segment. 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 imaging sensor is a crucial determinant 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. 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 Sony NEX-3 an APS-C sensor. The sensor area in the NEX-3 is 62 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.5. The sensor in the E-1 has a native 4:3 aspect ratio, while the one in the NEX-3 offers a 3:2 aspect.

With 14MP, the NEX-3 offers a higher resolution than the E-1 (4.9MP), but the NEX-3 has smaller individual pixels (pixel pitch of 5.11μm versus 6.78μm for the E-1). Yet, the NEX-3 is a much more recent model (by 6 years and 10 months) than the E-1, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Sony NEX-3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the NEX-3 for good quality output (200 dots per inch) amounts to 23 x 15.3 inches or 58.3 x 38.8 cm, for very good quality (250 dpi) 18.4 x 12.2 inches or 46.7 x 31 cm, and for excellent quality (300 dpi) 15.3 x 10.2 inches or 38.9 x 25.9 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 Sony Alpha NEX-3 are ISO 200 to ISO 12800 (no boost).

In terms of underlying technology, the E-1 is build around a CCD sensor, while the NEX-3 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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but can also record movies. The NEX-3 indeed provides for movie recording, while the E-1 does not. The highest resolution format that the NEX-3 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 E-1 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the NEX-3 relies on live view and the rear LCD for framing. That said, the NEX-3 can be equipped with an optional viewfinder – the FDA-SV1. The following table reports on some other key feature differences and similarities of the Olympus E-1, the Sony NEX-3, and comparable cameras.

One feature that is present on the E-1, but is missing on the NEX-3 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 E-1 writes its imaging data to Compact Flash or xD Picture cards, while the NEX-3 uses SDXC or Memory Stick PRO Duo cards. The E-1 features dual card slots, which can be very useful in case a memory card fails. In contrast, the NEX-3 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 Sony Alpha NEX-3 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 NEX-3) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the E-1 and the NEX-3 have been discontinued, but can regularly be found used on ebay. The E-1 was replaced by the Olympus E-3, while the NEX-3 was followed by the Sony NEX-3N. Further information on the features and operation of the E-1 and NEX-3 can be found, respectively, in the Olympus E-1 Manual (free pdf) or the online Sony NEX-3 Manual.

Review summary

So what is the bottom line? Is the Olympus E-1 better than the Sony NEX-3 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Olympus E-1:

• 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.
• Longer lasting: Can take more shots (750 versus 330) on a single battery charge.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More heavily discounted: Has been available for much longer (launched in June 2003).

Arguments in favor of the Sony Alpha NEX-3:

• More detail: Has more megapixels (14 vs 4.9MP), which boosts linear resolution by 72%.
• Better image quality: Is equipped with a larger and more technologically advanced sensor.
• Richer colors: The sensor size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
• Broader imaging potential: Can capture not only stills but also 720/30p video.
• Larger screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (920k vs 134k dots).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (7 vs 3 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (117x62mm vs 141x104mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 441g or 60 percent) and is thus easier to take along.
• More legacy lens friendly: Can use many non-native lenses via adapters.
• More affordable: Was introduced into a lower priced category (65 percent cheaper at launch).
• More modern: Reflects 6 years and 10 months of technical progress since the E-1 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the NEX-3 is the clear winner of the contest (16 : 7 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 Olympus E-1 and the Sony NEX-3 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the E-1 or the NEX-3. 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 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.

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

The above review scores should be interpreted 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. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
