Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm X-M1 and the Olympus E-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 Fujifilm X-M1 and the Olympus E-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 size dimensions are rounded to the nearest millimeter.

The X-M1 can be obtained in three different colors (black, silver, brown), 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 Olympus E-1 is considerably larger (87 percent) than the Fujifilm X-M1. Moreover, the E-1 is substantially heavier (124 percent) than the X-M1. It is noteworthy in this context that the E-1 is splash and dust-proof, while the X-M1 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 Fujinon X Lens Catalog (X-M1) and the Four Thirds Lens Catalog (E-1). Mirrorless cameras, such as the Fujifilm X-M1, have moreover the advantage that they have a relatively short flange to focal plane distance and can thus use many lenses from other systems via adapters.

Concerning battery life, the X-M1 gets 350 shots out of its Fujifilm NP-W126 battery, while the E-1 can take 750 images on a single charge of its Olympus BLM-1 power pack.

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

The price is, of course, an important factor in any camera decision. 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 X-M1 was launched at a markedly lower price (by 59 percent) than the E-1, which puts it into a different market segment. 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 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 Fujifilm X-M1 features an APS-C sensor and the Olympus E-1 a Four Thirds sensor. The sensor area in the E-1 is 39 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.0. The sensor in the X-M1 has a native 3:2 aspect ratio, while the one in the E-1 offers a 4:3 aspect.

With 16MP, the X-M1 offers a higher resolution than the E-1 (4.9MP), but the X-M1 has smaller individual pixels (pixel pitch of 4.80μm versus 6.78μm for the E-1). However, the X-M1 is a much more recent model (by 10 years) than the E-1, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the X-M1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Fujifilm X-M1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the X-M1 for good quality output (200 dots per inch) amounts to 24.5 x 16.3 inches or 62.2 x 41.5 cm, for very good quality (250 dpi) 19.6 x 13.1 inches or 49.7 x 33.2 cm, and for excellent quality (300 dpi) 16.3 x 10.9 inches or 41.5 x 27.6 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 Fujifilm X-M1 has a native sensitivity range from ISO 200 to ISO 6400, which can be extended to ISO 100-25600. The corresponding ISO settings for the Olympus E-1 are ISO 100 to ISO 800, with the possibility to increase the ISO range to 100-3200.

In terms of underlying technology, the X-M1 is build around a CMOS sensor, while the E-1 uses a CCD imager. The X-M1 uses Fujifilm's X-Trans layout of photosites, while the E-1 employs the more common Bayer array.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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").

Many modern cameras cannot only take still pictures, but also record videos. The X-M1 indeed provides movie recording capabilities, while the E-1 does not. The highest resolution format that the X-M1 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 X-M1 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Fujifilm X-M1 and Olympus E-1 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The X-M1 has one, while the E-1 does not. While the built-in flash of the X-M1 is not very powerful, it can at times be useful as a fill-in light.

The X-M1 writes its imaging data to SDXC cards, while the E-1 uses Compact Flash or xD Picture cards. The E-1 features dual card slots, which can be very useful in case a memory card fails. In contrast, the X-M1 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 Fujifilm X-M1 and Olympus E-1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the X-M1 offers wifi support, while the E-1 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Studio photographers will appreciate that the Olympus E-1 (unlike the X-M1) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the X-M1 and the E-1 have been discontinued, but can regularly be found used on ebay. The E-1 was replaced by the Olympus E-3, while the X-M1 was followed by the Fujifilm X-M5. Further information on the features and operation of the X-M1 and E-1 can be found, respectively, in the Fujifilm X-M1 Manual (free pdf) or the online Olympus E-1 Manual.

Review summary

So what is the bottom line? Is the Fujifilm X-M1 better than the Olympus E-1 or vice versa? The listing below highlights the relative strengths of the two models.

Advantages of the Fujifilm X-M1:

• More detail: Offers more megapixels (16 vs 4.9MP) with a 84% higher linear resolution.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Features a larger and more technologically advanced imaging 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 record not only still images but also 1080/30p movies.
• 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.
• Faster burst: Shoots at higher frequency (5.6 vs 3 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (117x67mm vs 141x104mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 408g or 55 percent) and hence easier to carry around.
• More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More affordable: Was introduced into a lower priced category (59 percent cheaper at launch).
• More modern: Reflects 10 years of technical progress since the E-1 launch.

Arguments in favor of the Olympus E-1:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Easier framing: Has an optical viewfinder for image composition and settings control.
• Easier setting verification: Features a control panel on top to check shooting parameters.
• Longer lasting: Gets more shots (750 versus 350) out of a single battery charge.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• 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 around for much longer (launched in June 2003).

If the count of relative strengths (bullet points above) is taken as a measure, the X-M1 is the clear winner of the match-up (19 : 8 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision 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 Fujifilm X-M1 and the Olympus E-1 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR 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 says little about, for example, the shooting experience and imaging performance of the X-M1 and the E-1 in practical situations. 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 table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
