Going beyond this snapshot of core features and characteristics, what are the differences between the Leica Q3 and the Nikon D3X? 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 Q3 and the Nikon D3X are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.



If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D3X is considerably larger (142 percent) than the Leica Q3. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the Q3 has a lens built in, whereas the D3X 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 D3X and their specifications in the Nikon Lens Catalog.
Concerning battery life, the Q3 gets 350 shots out of its Leica BP-SCL6 battery, while the D3X can take 4400 images on a single charge of its Nikon EN-EL4a power pack. As can be seen in the images above, the D3X has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. The power pack in the Q3 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Q3 was launched at a lower price than the D3X, despite having a lens built in. 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 more expensive and lead to bigger and heavier cameras and lenses.
Both cameras under consideration feature a full frame sensor, but their sensors differ slightly in size. They nevertheless have the same format factor of 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 D3X (24.4MP), but the Q3 has smaller individual pixels (pixel pitch of 3.79μm versus 5.94μm for the D3X). However, the Q3 is a much more recent model (by 14 years and 5 months) than the D3X, and its sensor will have benefitted from technological advances during this time that 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 Nikon D3X are 30.2 x 20.2 inches or 76.8 x 51.2 cm for good quality, 24.2 x 16.1 inches or 61.4 x 41 cm for very good quality, and 20.2 x 13.4 inches or 51.2 x 34.1 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 Nikon D3X are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 50-6400.
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"). 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. The Q3 indeed provides movie recording capabilities, while the D3X does not. The highest resolution format that the Q3 can use is 8K/30p.
Feature comparison
Beyond body and sensor, cameras can and do differ across a range of features. For example, the Q3 has an electronic viewfinder (5760k dots), while the D3X 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 viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the Q3 has a higher magnification than the one of the D3X (0.79x vs 0.70x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Leica Q3 and Nikon D3X in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The Q3 has a touchscreen, while the D3X 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 and the Nikon D3X 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.
The Q3 writes its imaging data to SDXC cards, while the D3X uses Compact Flash cards. The D3X features dual card slots, which can be very useful in case a memory card fails. In contrast, the Q3 only has one slot.
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 Nikon D3X and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the Q3 offers wifi support, while the D3X does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Studio photographers will appreciate that the Nikon D3X (unlike the Q3) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The Q3 is a recent model that features in the current product line-up of Leica. In contrast, the D3X has been discontinued (but can be found pre-owned on ebay). There has not been a direct replacement model for the D3X from Nikon. Further information on the features and operation of the Q3 and D3X can be found, respectively, in the Leica Q3 Manual (free pdf) or the online Nikon D3X Manual.
Review summary
So what conclusions can be drawn? Which of the two cameras – the Leica Q3 or the Nikon D3X – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

- More heavily discounted: Has been around for much longer (launched in December 2008).
If the number of relative strengths (bullet points above) is taken as a guide, the Q3 is the clear winner of the match-up (22 : 10 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 Leica Q3 and the Nikon D3X place the cameras among the top in their class? Find out in the latest Best Prime Lens Compact Camera and Best DSLR 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 Q3 and the D3X in practical situations. 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.

Care should be taken when interpreting the review scores above, 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 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.
