Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus OM-D E-M10 and the Fujifilm X100T? 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

An illustration of the physical size and weight of the Olympus E-M10 and the Fujifilm X100T is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.

Both cameras are available in two different colors (black, silver).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Fujifilm X100T is somewhat smaller (4 percent) than the Olympus E-M10. In this context, it is worth noting that neither the E-M10 nor the X100T are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the X100T has a lens built in, whereas the E-M10 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-M10 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the E-M10 gets 320 shots out of its Olympus BLS-5 battery, while the X100T can take 330 images on a single charge of its Fujifilm NP-95 power pack. The power pack in the X100T can be charged via the USB port, which can be very convenient when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 naturally be influenced heavily by the price. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. 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-M10 features a Four Thirds sensor and the Fujifilm X100T an APS-C sensor. The sensor area in the X100T is 64 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-M10 has a native 4:3 aspect ratio, while the one in the X100T offers a 3:2 aspect.

With 16MP, the X100T offers a higher resolution than the E-M10 (15.9MP), but the X100T nevertheless has larger individual pixels (pixel pitch of 4.80μm versus 3.76μm for the E-M10) due to its larger sensor. Moreover, the X100T is a somewhat more recent model (by 7 months) than the E-M10, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The X100T has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Olympus OM-D E-M10 has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600. The corresponding ISO settings for the Fujifilm X100T are ISO 200 to ISO 6400, with the possibility to increase the ISO range to 100-51200.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Like most digital cameras, the E-M10 uses a Bayer filter for capturing RGB colors on a square grid of photosensors. In contrast, the X100T employs a more randomized X-Trans layout of photosites, which according to Fujifilm helps to minimize moiré.

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"). 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 also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the X100T provides a faster frame rate than the E-M10. It can shoot movie footage at 1080/60p, while the Olympus is limited to 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the X100T offers a substantially higher resolution than the one in the E-M10 (2360k vs 1440k dots). The table below summarizes some of the other core capabilities of the Olympus E-M10 and Fujifilm X100T in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The E-M10 has a touchscreen, while the X100T has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The Olympus E-M10 and the Fujifilm X100T both have 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.

Concerning the storage of imaging data, both the E-M10 and the X100T write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

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 OM-D E-M10 and Fujifilm X100T and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the X100T has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The E-M10 does not feature such a mic input.

Both the E-M10 and the X100T have been discontinued, but can regularly be found used on ebay. The E-M10 was replaced by the Olympus E-M10 II, while the X100T was followed by the Fujifilm X100F. Further information on the features and operation of the E-M10 and X100T can be found, respectively, in the Olympus E-M10 Manual (free pdf) or the online Fujifilm X100T Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Olympus E-M10 or the Fujifilm X100T – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

Advantages of the Olympus OM-D E-M10:

• Larger viewfinder image: Features a viewfinder with a higher magnification (0.58x vs 0.43x).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• Faster burst: Shoots at higher frequency (8 vs 6 flaps/sec) to capture the decisive moment.
• More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• More heavily discounted: Has been on the market for longer (launched in January 2014).

Reasons to prefer the Fujifilm X100T:

• 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.
• Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• Better sound: Can connect to an external microphone for higher quality sound recording.
• More detailed viewfinder: Has higher resolution electronic viewfinder (2360k vs 1440k dots).
• Ready to shoot: Has an integrated lens, whereas the E-M10 necessitates an extra lens.
• Easier travel charging: Can be conveniently charged via its USB port.
• More modern: Was introduced somewhat (7 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the X100T is the clear winner of the contest (11 : 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-M10 and the Fujifilm X100T place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Prime Lens Compact 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 says little about, for example, the shooting experience and imaging performance of the E-M10 and the X100T in practical situations. 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 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.

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.
