Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS RP 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.
An illustration of the physical size and weight of the Canon RP and the Nikon D3X is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth 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 (122 percent) than the Canon RP. Moreover, the D3X is substantially heavier (160 percent) than the Canon RP. It is noteworthy in this context that the D3X is splash and dust-proof, while the Canon RP does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.
Concerning battery life, the Canon RP gets 250 shots out of its LP-E17 battery, while the D3X can take 4400 images on a single charge of its 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 Canon RP can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

Any camera decision will naturally be influenced heavily by the price. 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 Canon RP was launched at a markedly lower price (by 84 percent) than the D3X, 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.
The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Both cameras under consideration feature a full frame sensor and have a format factor (sometimes also referred to as "crop factor") of 1.0. Within the spectrum of camera sensors, this places the review cameras among the large-sensor cameras that aim for top notch image quality. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
While the two cameras under review share the same sensor size, the Canon RP offers a slightly higher resolution of 26.2 megapixels, compared with 24.4 MP of the D3X. This megapixels advantage translates into a 3 percent gain in linear resolution. On the other hand, these sensor specs imply that the Canon RP has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 5.74μm versus 5.94μm for the D3X). In this context, it should be noted, however, that the Canon RP is much more recent (by 10 years and 2 months) than the D3X, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.
The Canon RP has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS RP has a native sensitivity range from ISO 100 to ISO 40000, which can be extended to ISO 50-102400. 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.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The Canon RP indeed provides movie recording capabilities, while the D3X does not. The highest resolution format that the Canon RP can use is 4K/30p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the Canon RP has an electronic viewfinder (2360k 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%), as well as the same magnification (0.70x). The adjacent table lists some of the other core features of the Canon RP and Nikon D3X along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The Canon RP has a touchscreen, while the D3X has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The Canon RP has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the D3X does not have a selfie-screen.
The Canon RP 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 Canon RP 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 Canon RP only has one slot.
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 Canon EOS RP 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 Canon RP 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 Canon RP) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The Canon RP is a recent model that features in the current product line-up of Canon. In contrast, the D3X has been discontinued (but it can be found pre-owned on eBay). There has not been a direct replacement model for the D3X from Nikon. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Nikon websites.
So how do things add up? Is there a clear favorite between the Canon RP and the Nikon D3X? Which camera is better? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Canon EOS RP:
- Broader imaging potential: Can record not only still images but also 4K/30p movies.

- More heavily discounted: Has been around for much longer (launched in December 2008).
If the count of relative strengths (bullet points above) is taken as a measure, the Canon RP is the clear winner of the match-up (14 : 9 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 Canon RP and the Nikon D3X place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens 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 remains incomplete and does no justice, for example, to the way the Canon RP or the D3X perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.
This is where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
