Going beyond this snapshot of core features and characteristics, what are the differences between the Leica X Vario (Typ 107) and the Sony Cyber-shot DSC-RX100 IV? 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 physical size and weight of the Leica X Vario and the Sony RX100 IV are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures are rounded to the nearest millimeter.

The X Vario can be obtained in two different colors (black, silver), while the RX100 IV 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 RX100 IV is considerably smaller (39 percent) than the Leica X Vario. Moreover, the RX100 IV is substantially lighter (56 percent) than the X Vario. In this context, it is worth noting that neither the X Vario nor the RX100 IV are weather-sealed.

Concerning battery life, the X Vario gets 450 shots out of its Leica BP-DC8 battery, while the RX100 IV can take 280 images on a single charge of its Sony NP-BX1 power pack. The power pack in the RX100 IV can be charged via the USB port, which can be very convenient when travelling.

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 RX100 IV was launched at a markedly lower price (by 65 percent) than the X Vario, 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. 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. 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 Leica X Vario features an APS-C sensor and the Sony RX100 IV an one-inch sensor. The sensor area in the RX100 IV is 69 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.7. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Despite having a smaller sensor, the RX100 IV offers a higher resolution of 20 megapixels, compared with 16.1 MP of the X Vario. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 2.41μm versus 4.80μm for the X Vario). However, it should be noted that the RX100 IV is a somewhat more recent model (by 1 year and 11 months) than the X Vario, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.

The resolution advantage of the Sony RX100 IV implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX100 IV for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Leica X Vario are 24.6 x 16.4 inches or 62.6 x 41.6 cm for good quality, 19.7 x 13.1 inches or 50.1 x 33.2 cm for very good quality, and 16.4 x 10.9 inches or 41.7 x 27.7 cm for excellent quality prints.

The Leica X Vario (Typ 107) has a native sensitivity range from ISO 100 to ISO 12500. The corresponding ISO settings for the Sony Cyber-shot DSC-RX100 IV are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 80-25600.

In terms of underlying technology, the X Vario is build around a CMOS sensor, while the RX100 IV uses a BSI-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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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"). Of the two cameras under review, the X Vario has a notably higher overall DXO score than the RX100 IV (overall score 8 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.6 bits higher color depth, 0.1 EV in additional dynamic range, and 1.2 stops in additional low light sensitivity. 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 cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the RX100 IV provides a better video resolution than the X Vario. It can shoot movie footage at 4K/30p, while the Leica is limited to 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the RX100 IV has an electronic viewfinder (2359k dots), which can be very helpful when shooting in bright sunlight. In contrast, the X Vario relies on live view and the rear LCD for framing. That said, the X Vario can be equipped with an optional viewfinder – the EVF 2. The following table reports on some other key feature differences and similarities of the Leica X Vario, the Sony RX100 IV, and comparable cameras.

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

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 RX100 IV 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).

Both the X Vario and the RX100 IV have zoom lenses built in. The X Vario has a 28-70mm f/3.5-6.4 optic and the RX100 IV offers a 24-70mm f/1.8-2.8 (focal lengths in full frame equivalent terms). Hence, the Sony provides a wider angle of view at the short end than the Leica and the same tele-photo reach at the long end. The RX100 IV offers the faster maximum aperture.

The X Vario writes its imaging data to SDXC cards, while the RX100 IV uses SDXC or Memory Stick PRO Duo cards. The RX100 IV supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the X Vario 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 X Vario (Typ 107) and Sony Cyber-shot DSC-RX100 IV and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the X Vario has a hotshoe, while the RX100 IV does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Both the X Vario and the RX100 IV have been discontinued, but can regularly be found used on ebay. The RX100 IV was replaced by the Sony RX100 IV, while the X Vario does not have a direct successor. Further information on the features and operation of the X Vario and RX100 IV can be found, respectively, in the Leica X Vario Manual (free pdf) or the online Sony RX100 IV Manual.

Review summary

So what is the bottom line? Is the Leica X Vario better than the Sony RX100 IV or vice versa? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Leica X Vario (Typ 107):

• Better image quality: Scores markedly higher (8 points) in the DXO overall assessment.
• Better low-light sensitivity: Requires less light for good images (1.2 stops ISO advantage).
• Longer lasting: Can take more shots (450 versus 280) on a single battery charge.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale price.
• More heavily discounted: Has been on the market for longer (launched in June 2013).

Reasons to prefer the Sony Cyber-shot DSC-RX100 IV:

• More detail: Has more megapixels (20 vs 16.1MP), which boosts linear resolution by 11%.
• Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• More detailed LCD: Has a higher resolution rear screen (1228k vs 920k 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 (16 vs 5 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Better light gathering: Has a lens with a wider maximum aperture (f/1.8 vs f/3.5).
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• More compact: Is smaller (102x58mm vs 133x73mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 382g or 56 percent) and is thus easier to take along.
• Easier travel charging: Can be conveniently charged via its USB port.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.

• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More affordable: Was introduced into a lower priced category (65 percent cheaper at launch).
• More modern: Was introduced somewhat (1 year and 11 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the RX100 IV is the clear winner of the contest (19 : 6 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 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 X Vario and the Sony RX100 IV place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera listing 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 Vario and the RX100 IV 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 why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major 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 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. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
