Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm X-T10 and the Leica Q3? 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 Fujifilm X-T10 and the Leica Q3 is provided in the side-by-side display below. 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 dimensions are rounded to the nearest millimeter.

The X-T10 can be obtained in two different colors (black, silver), while the Q3 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 Leica Q3 is notably larger (6 percent) than the Fujifilm X-T10. It is noteworthy in this context that the Q3 is splash and dust-proof, while the X-T10 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the Q3 has a lens built in, whereas the X-T10 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 X-T10 and their specifications in the Fujinon X Lens Catalog.

The power pack in the Q3 can be charged via the USB port, which can be very convenient when travelling.

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. 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. 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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-T10 features an APS-C sensor and the Leica Q3 a full frame sensor. The sensor area in the Q3 is 135 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 60.3MP, the Q3 offers a higher resolution than the X-T10 (16MP), but the Q3 has smaller individual pixels (pixel pitch of 3.79μm versus 4.80μm for the X-T10). Yet, the Q3 is a much more recent model (by 8 years) than the X-T10, and its sensor will have benefitted from technological advances during this time that 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 resolution advantage of the Leica Q3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Q3 for good quality output (200 dots per inch) amounts to 47.6 x 31.6 inches or 121 x 80.4 cm, for very good quality (250 dpi) 38.1 x 25.3 inches or 96.8 x 64.3 cm, and for excellent quality (300 dpi) 31.8 x 21.1 inches or 80.7 x 53.6 cm. The corresponding values for the Fujifilm X-T10 are 24.5 x 16.3 inches or 62.2 x 41.5 cm for good quality, 19.6 x 13.1 inches or 49.7 x 33.2 cm for very good quality, and 16.3 x 10.9 inches or 41.5 x 27.6 cm for excellent quality prints.

The Fujifilm X-T10 has a native sensitivity range from ISO 200 to ISO 6400, which can be extended to ISO 100-51200. The corresponding ISO settings for the Leica Q3 are ISO 50 to ISO 100000 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. The X-T10 uses Fujifilm's X-Trans layout of photosites, while the Q3 employs the more common Bayer array.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the Q3 provides a better video resolution than the X-T10. It can shoot movie footage at 8K/30p, while the Fujifilm is limited to 1080/60p.

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 Q3 offers a substantially higher resolution than the one in the X-T10 (5760k vs 2360k dots). The adjacent table lists some of the other core features of the Fujifilm X-T10 and Leica Q3 along with similar information for a selection of comparators.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One difference between the cameras concerns the presence of an on-board flash. The X-T10 has one, while the Q3 does not. While the built-in flash of the X-T10 is not very powerful, it can at times be useful as a fill-in light.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the Q3 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Fujifilm X-T10 and the Leica Q3 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 X-T10 and the Q3 write their files to SDXC cards. The Q3 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the X-T10 can use UHS-I cards (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 Fujifilm X-T10 and Leica Q3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the X-T10 has a microphone port, which is missing on the Q3. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

The Q3 is a recent model that features in the current product line-up of Leica. In contrast, the X-T10 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the X-T10 was succeeded by the Fujifilm X-T20. Further information on the features and operation of the X-T10 and Q3 can be found, respectively, in the Fujifilm X-T10 Manual (free pdf) or the online Leica Q3 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Fujifilm X-T10 and the Leica Q3? Which camera is better? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Fujifilm X-T10:

• Better sound: Can connect to an external microphone for higher quality sound recording.

• More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• More heavily discounted: Has been available for much longer (launched in May 2015).

Advantages of the Leica Q3:

• More detail: Has more megapixels (60.3 vs 16MP), which boosts linear resolution by 94%.
• 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 definition movie capture (8K/30p vs 1080/60p).
• More detailed viewfinder: Has higher resolution electronic viewfinder (5760k vs 2360k dots).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.79x vs 0.41x).
• More detailed LCD: Has a higher resolution rear screen (1840k vs 920k dots).
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Faster burst: Shoots at higher frequency (15 vs 8 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Ready to shoot: Has an integrated lens, whereas the X-T10 necessitates an extra lens.
• Easier travel charging: Can be conveniently charged via its USB port.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.

• More modern: Reflects 8 years of technical progress since the X-T10 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the Q3 is the clear winner of the contest (21 : 5 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 Fujifilm X-T10 and the Leica Q3 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 comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the X-T10 or the Q3 perform in practice. 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 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.

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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
