Any camera decision will naturally be influenced heavily by the price. 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 RX100 was launched at a markedly lower price (by 89 percent) than the Q3, 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Leica Q3 features a full frame sensor and the Sony RX100 an one-inch sensor. The sensor area in the RX100 is 87 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.7. 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 RX100 (20MP), but the Q3 nevertheless has larger individual pixels (pixel pitch of 3.79μm versus 2.41μm for the RX100) due to its larger sensor. Moreover, the Q3 is a much more recent model (by 10 years and 11 months) than the RX100, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the Q3 has no anti-alias filter installed, so that it can capture all the detail its 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 Sony RX100 are 27.4 x 18.2 inches or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inches or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inches or 46.3 x 30.9 cm for excellent quality prints.
The Q3 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Leica Q3 has a native sensitivity range from ISO 50 to ISO 100000. The corresponding ISO settings for the Sony Cyber-shot DSC-RX100 are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-25600.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. 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").

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 Q3 provides a higher video resolution than the RX100. It can shoot video footage at 8K/30p, while the Sony is limited to 1080/60p.
Feature comparison
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the Q3 has an electronic viewfinder (5760k dots), which can be very helpful when shooting in bright sunlight. In contrast, the RX100 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Leica Q3, the Sony RX100, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The Q3 has a touchscreen, while the RX100 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
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 Leica Q3 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 RX100 is equipped with a zoom lens, while the Q3 comes with a built-in prime. The RX100 has a 28-100mm f/1.8-4.9 optic and the Q3 offers a 28mm f/1.7 (focal lengths in full frame equivalent terms). Hence, the Leica and Sony provide the same view at the wide-angle end, but the Sony has less tele-photo reach at the long end. The Q3 offers the faster maximum aperture.
The Q3 writes its imaging data to SDXC cards, while the RX100 uses SDXC or Memory Stick PRO Duo cards. The Q3 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the RX100 cannot take advantage of Ultra High Speed SD cards.
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 Leica Q3 and Sony Cyber-shot DSC-RX100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the Q3 has a hotshoe, while the RX100 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
The Q3 is a recent model that features in the current product line-up of Leica. In contrast, the RX100 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the RX100 was succeeded by the Sony RX100 II. Further information on the features and operation of the Q3 and RX100 can be found, respectively, in the Leica Q3 Manual (free pdf) or the online Sony RX100 Manual.
Review summary
So what is the bottom line? Is the Leica Q3 better than the Sony RX100 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Leica Q3:
- More detail: Offers more megapixels (60.3 vs 20MP) with a 74% 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.
- Better video: Provides higher definition movie capture (8K/30p vs 1080/60p).
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- More detailed LCD: Has a higher resolution rear screen (1840k vs 1229k dots).
- 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 (15 vs 10 flaps/sec) to capture the decisive moment.
- Less disturbing: Has an electronic shutter option for completely silent shooting.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Better light gathering: Has a lens with a wider maximum aperture (f/1.7 vs f/1.8).
- Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- Faster data transfer: Supports a more advanced USB protocol (3.1 vs 2.0).
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.

- More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
- More modern: Reflects 10 years and 11 months of technical progress since the RX100 launch.

Advantages of the Sony Cyber-shot DSC-RX100:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- More compact: Is smaller (102x58mm vs 130x80mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 503g or 68 percent) and is thus easier to take along.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- More affordable: Was introduced into a lower priced category (89 percent cheaper at launch).
- More heavily discounted: Has been around for much longer (launched in June 2012).
If the number of relative strengths (bullet points above) is taken as a guide, the Q3 is the clear winner of the match-up (24 : 6 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 Leica Q3 and the Sony RX100 place the cameras among the top in their class? Find out in the latest Best Prime Lens Compact Camera and Best Travel-Zoom 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 remains incomplete and does no justice, for example, to the way the Q3 or the RX100 perform in practice. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.
Expert reviews
This is why expert reviews 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.

The review scores listed above should be treated 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. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
