Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS Rebel SL3 and the Samsung NX1? 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 Canon SL3 and the Samsung NX1 is provided 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.

The SL3 can be obtained in two different colors (black, white), while the NX1 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 Samsung NX1 is notably larger (25 percent) than the Canon SL3. Moreover, the NX1 is markedly heavier (22 percent) than the SL3. It is noteworthy in this context that the NX1 is splash and dust-proof, while the SL3 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.

The power pack in the NX1 can be charged via the USB port, which can be very convenient when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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 SL3 was launched at a markedly lower price (by 60 percent) than the NX1, 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 sensor inside a digital camera is one of the key determinants 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. 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 tend to be associated with larger, more expensive camera bodies and lenses.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the NX1 is 11 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (SL3) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 28MP, the NX1 offers a higher resolution than the SL3 (24MP), but the NX1 has marginally smaller individual pixels (pixel pitch of 3.63μm versus 3.72μm for the SL3). Yet, the SL3 is a much more recent model (by 4 years and 6 months) than the NX1, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the NX1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Samsung NX1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the NX1 for good quality output (200 dots per inch) amounts to 32.4 x 21.6 inches or 82.3 x 54.9 cm, for very good quality (250 dpi) 25.9 x 17.3 inches or 65.8 x 43.9 cm, and for excellent quality (300 dpi) 21.6 x 14.4 inches or 54.9 x 36.6 cm. The corresponding values for the Canon SL3 are 30 x 20 inches or 76.2 x 50.8 cm for good quality, 24 x 16 inches or 61 x 40.6 cm for very good quality, and 20 x 13.3 inches or 50.8 x 33.9 cm for excellent quality prints.

The Canon EOS Rebel SL3 has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 100-51200. The Samsung NX1 offers exactly the same ISO settings.

In terms of underlying technology, the SL3 is build around a CMOS sensor, while the NX1 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.

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 cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the NX1 provides a faster frame rate than the SL3. It can shoot movie footage at 4K/30p, while the Canon is limited to 4K/25p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the NX1 has an electronic viewfinder (2360k dots), while the SL3 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 viewfinder in the NX1 offers a wider field of view (100%) than the one in the SL3 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the NX1 has a higher magnification (0.69x vs 0.54x), 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 Canon SL3 and Samsung NX1 in connection with corresponding information for a sample of similar cameras.

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

One feature that is present on the NX1, but is missing on the SL3 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

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 NX1 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 Canon SL3 and the Samsung NX1 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.

Concerning the storage of imaging data, both the SL3 and the NX1 write their files to SDXC cards. The NX1 supports UHS-II cards (on its first slot), while the SL3 can use UHS-I 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 Canon EOS Rebel SL3 and Samsung NX1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the NX1 has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The SL3 lacks such a headphone port.

The SL3 is a recent model that features in the current product line-up of Canon. In contrast, the NX1 has been discontinued (but can be found pre-owned on ebay). There has not been a direct replacement model for the NX1 from Samsung. Further information on the features and operation of the SL3 and NX1 can be found, respectively, in the Canon SL3 Manual (free pdf) or the online Samsung NX1 Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Canon SL3 or the Samsung NX1 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Canon EOS Rebel SL3:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• 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.
• More compact: Is smaller (122x93mm vs 139x102mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 101g or 18 percent) and hence easier to carry around.
• Longer lasting: Can take more shots (1070 versus 500) on a single battery charge.
• More affordable: Was introduced into a lower priced category (60 percent cheaper at launch).
• More modern: Reflects 4 years and 6 months of technical progress since the NX1 launch.

Advantages of the Samsung NX1:

• More detail: Has more megapixels (28 vs 24MP), which boosts linear resolution by 8%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better video: Provides higher movie framerates (4K/30p versus 4K/25p).
• Better sound control: Has a headphone port that enables audio monitoring while recording.
• More framing info: Has an electronic viewfinder that displays shooting data.
• More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.69x vs 0.54x).
• Easier setting verification: Features a control panel on top to check shooting parameters.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• Faster burst: Shoots at higher frequency (15 vs 5 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Easier travel charging: Can be conveniently charged via its USB port.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• More legacy lens friendly: Can use many non-native lenses via adapters.
• Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
• More heavily discounted: Has been around for much longer (launched in September 2014).

If the count of individual advantages (bullet points above) is taken as a guide, the NX1 is the clear winner of the contest (18 : 9 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. 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 Canon SL3 and the Samsung NX1 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the SL3 or the NX1 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.

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.

The review scores listed above should be treated 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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
