Going beyond this snapshot of core features and characteristics, what are the differences between the Leica D-LUX 7 and the Sony Alpha NEX-F3? 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 Leica D-LUX 7 and the Sony NEX-F3 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 NEX-F3 can be obtained in three different colors (black, silver, white), while the D-LUX 7 is only available in silver.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony NEX-F3 is somewhat larger (3 percent) than the Leica D-LUX 7. In this context, it is worth noting that neither the D-LUX 7 nor the NEX-F3 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the D-LUX 7 has a lens built in, whereas the NEX-F3 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 NEX-F3 and their specifications in the Sony E-Mount Lens Catalog.

Concerning battery life, the D-LUX 7 gets 300 shots out of its BP-DC15 battery, while the NEX-F3 can take 470 images on a single charge of its NP-FW50 power pack. The power pack in the D-LUX 7 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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 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 Leica D-LUX 7 features a Four Thirds sensor and the Sony NEX-F3 an APS-C sensor. The sensor area in the NEX-F3 is 97 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.2 and 1.5. The sensor in the D-LUX 7 has a native 4:3 aspect ratio, while the one in the NEX-F3 offers a 3:2 aspect. The D-LUX 7 has the particularity of featuring a switch that allows to toggle between multiple aspect ratios, while maintaining the same field of view and full image resolution.

Despite having a smaller sensor, the Leica D-LUX 7 offers a higher resolution of 16.8 megapixels, compared with 16 MP of the Sony NEX-F3. 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 3.32μm versus 4.78μm for the NEX-F3). However, it should be noted that the D-LUX 7 is much more recent (by 6 years and 6 months) than the NEX-F3, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the D-LUX 7 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The Leica D-LUX 7 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 Sony Alpha NEX-F3 are ISO 100 to ISO 16000 (no boost).

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.

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"). 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 can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the D-LUX 7 provides a higher video resolution than the NEX-F3. It can shoot video footage at 4K/30p, while the Sony is limited to 1080/60i.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the D-LUX 7 has an electronic viewfinder (2764k dots), which can be very helpful when shooting in bright sunlight. In contrast, the NEX-F3 relies on live view and the rear LCD for framing. That said, the NEX-F3 can be equipped with an optional viewfinder – the FDA-EV1S. The adjacent table lists some of the other core features of the Leica D-LUX 7 and Sony NEX-F3 along with similar information for a selection of comparators.

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

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The D-LUX 7 has a touchscreen, while the NEX-F3 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 D-LUX 7 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 D-LUX 7 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 D-LUX 7 writes its imaging data to SDXC cards, while the NEX-F3 uses SDXC or Memory Stick PRO Duo cards. The D-LUX 7 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the NEX-F3 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 D-LUX 7 and Sony Alpha NEX-F3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D-LUX 7 offers wifi support, while the NEX-F3 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

The D-LUX 7 is a recent model that features in the current product line-up of Leica. In contrast, the NEX-F3 has been discontinued (but can be found pre-owned on ebay). There has not been a direct replacement model for the NEX-F3 from Sony. Further information on the features and operation of the D-LUX 7 and NEX-F3 can be found, respectively, in the Leica D-LUX 7 Manual (free pdf) or the online Sony NEX-F3 Manual.

Review summary

So what conclusions can be drawn? Is the Leica D-LUX 7 better than the Sony NEX-F3 or vice versa? The listing below highlights the relative strengths of the two models.

Advantages of the Leica D-LUX 7:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Flexible image proportions: Has a multi-aspect sensor that allows for alternative image shapes.
• Better video: Provides higher definition movie capture (4K/30p vs 1080/60i).
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• More detailed LCD: Has a higher resolution rear screen (1240k vs 920k dots).
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• Faster burst: Shoots at higher frequency (11 vs 5.5 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.
• Ready to shoot: Has a lens built-in, whereas the NEX-F3 requires a separate lens.
• Easier travel charging: Can be conveniently charged via its USB port.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• 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 price.
• More modern: Reflects 6 years and 6 months of technical progress since the NEX-F3 launch.

Arguments in favor of the Sony Alpha NEX-F3:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• 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.
• More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
• Longer lasting: Gets more shots (470 versus 300) out of a single battery charge.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• More heavily discounted: Has been around for much longer (launched in May 2012).

If the number of relative strengths (bullet points above) is taken as a guide, the D-LUX 7 is the clear winner of the match-up (17 : 7 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 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 Leica D-LUX 7 and the Sony NEX-F3 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the D-LUX 7 or the NEX-F3 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 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 review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
