Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm X20 and the Leica V-LUX 4? 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 X20 and the Leica V-LUX 4 is provided 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 X20 can be obtained in two different colors (black, silver), while the V-LUX 4 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 V-LUX 4 is notably larger (33 percent) than the Fujifilm X20. Moreover, the V-LUX 4 is substantially heavier (67 percent) than the X20. In this context, it is worth noting that neither the X20 nor the V-LUX 4 are weather-sealed.

Concerning battery life, the X20 gets 270 shots out of its Fujifilm NP-50 battery, while the V-LUX 4 can take 540 images on a single charge of its Leica BP-DC12 power pack.

Any camera decision will obviously take relative prices into account. 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. The X20 was launched at a markedly lower price (by 37 percent) than the V-LUX 4, 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 imaging sensor is a crucial determinant of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Fujifilm X20 features a 2/3 sensor and the Leica V-LUX 4 a 1/2.3-inch sensor. The sensor area in the V-LUX 4 is 52 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 3.9 and 5.6. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Even though the X20 has a larger sensor, both cameras offer the same resolution of 12 megapixels. This implies that the X20 has a lower pixel density and larger individual pixels (with a pixel pitch of 2.20μm versus 1.53μm for the V-LUX 4), which gives it a potential advantage in terms of light gathering capacity. In addition, the X20 is a somewhat more recent model (by 3 months) than the V-LUX 4, and its sensor might have benefitted from technological advances during this time. 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 X20 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Fujifilm X20 has a native sensitivity range from ISO 100 to ISO 12800. The corresponding ISO settings for the Leica V-LUX 4 are ISO 100 to ISO 3200, with the possibility to increase the ISO range to 100-6400.

In terms of underlying technology, the X20 is build around a CMOS sensor, while the V-LUX 4 uses a BSI-CMOS imager. The X20 uses Fujifilm's X-Trans layout of photosites, while the V-LUX 4 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 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

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, and both provide the same movie specifications (1080/60p).

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the V-LUX 4 has an electronic viewfinder (1312k dots), while the X20 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The following table reports on some other key feature differences and similarities of the Fujifilm X20, the Leica V-LUX 4, and comparable cameras.

Both the X20 and the V-LUX 4 have zoom lenses built in. The X20 has a 28-112mm f/2.0-2.8 optic and the V-LUX 4 offers a 25-600mm f/2.8-2.8 (focal lengths in full frame equivalent terms). Hence, the Leica provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the Fujifilm. The X20 offers the faster maximum aperture.

Concerning the storage of imaging data, both the X20 and the V-LUX 4 write their files to SDXC cards. The V-LUX 4 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the X20 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 Fujifilm X20 and Leica V-LUX 4 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the V-LUX 4 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The X20 does not feature such a mic input.

Both the X20 and the V-LUX 4 have been discontinued, but can regularly be found used on ebay. The V-LUX 4 was replaced by the Leica V-LUX Typ 114, while the X20 was followed by the Fujifilm X30. Further information on the features and operation of the X20 and V-LUX 4 can be found, respectively, in the Fujifilm X20 Manual (free pdf) or the online Leica V-LUX 4 Manual.

Review summary

So what is the bottom line? Is the Fujifilm X20 better than the Leica V-LUX 4 or vice versa? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Fujifilm X20:

• Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
• Richer colors: The pixel size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• Better light gathering: Has a lens with a wider maximum aperture (f/2.0 vs f/2.8).
• More compact: Is smaller (117x70mm vs 125x87mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 235g or 40 percent) and hence easier to carry around.
• More affordable: Was introduced into a lower priced category (37 percent cheaper at launch).
• More modern: Is somewhat more recent (announced 3 months after the V-LUX 4).

Arguments in favor of the Leica V-LUX 4:

• Better sound: Can connect to an external microphone for higher quality sound recording.
• More framing info: Has an electronic viewfinder that displays shooting data.
• Larger screen: Has a bigger rear LCD (3.0" vs 2.8") for image review and settings control.
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• Longer lasting: Gets more shots (540 versus 270) out of a single battery charge.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
• More heavily discounted: Has been on the market for longer (launched in September 2012).

If the count of relative strengths (bullet points above) is taken as a measure, the match-up finishes in a tie (11 points each). 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 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 X20 and the Leica V-LUX 4 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Superzoom 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 X20 and the V-LUX 4 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 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 are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
