Samsung NX1 vs Sony A77 II
The Samsung NX1 and the Sony Alpha SLT-A77 II are two enthusiast cameras that were officially introduced, respectively, in September 2014 and May 2014. The NX1 is a mirrorless interchangeable lens camera, while the A77 II is a DSLR. Both cameras are equipped with an APS-C sensor. The Samsung has a resolution of 28 megapixels, whereas the Sony provides 24 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Samsung NX1 and the Sony Alpha SLT-A77 II? 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 Samsung NX1 and the Sony A77 II 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 Sony A77 II is somewhat larger (5 percent) than the Samsung NX1. Moreover, the A77 II is markedly heavier (18 percent) than the NX1. 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 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, 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. 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 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 A77 II was launched at a somewhat lower price (by 20 percent) than the NX1, which makes it more attractive for photographers on a tight budget. 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 imaging sensor is a crucial determinant of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units in a sensor of the same technological generation. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 A77 II is 1 percent smaller. They nevertheless have the same format factor of 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 A77 II (24MP), but the NX1 has smaller individual pixels (pixel pitch of 3.63μm versus 3.91μm for the A77 II). However, the NX1 is a somewhat more recent model (by 4 months) than the A77 II, and its sensor might 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 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 Sony A77 II 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 NX1 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Samsung NX1 has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 100-51200. The corresponding ISO settings for the Sony Alpha SLT-A77 II are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-51200.
For many cameras, data on sensor performance has been reported by DXO Mark. 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 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 two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the NX1 provides a higher video resolution than the A77 II. It can shoot video footage at 4K/30p, while the Sony is limited to 1080/60p.
Apart from body and sensor, cameras can and do differ across a range of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the NX1 offers a slightly higher resolution than the one in the A77 II (2360k vs 2359k dots). The following table reports on some other key feature differences and similarities of the Samsung NX1, the Sony A77 II, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The NX1 has a touchscreen, while the A77 II has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The A77 II has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the NX1 does not have a selfie-screen.
The Samsung NX1 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 NX1 writes its imaging data to SDXC cards, while the A77 II uses SDXC or Memory Stick PRO Duo cards. The NX1 supports UHS-II cards (on its first slot), while the A77 II can use UHS-I cards.
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 Samsung NX1 and Sony Alpha SLT-A77 II 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 is not present on the A77 II This port makes it possible to attach external headphones and monitor the quality of sound during the recording process.
Studio photographers will appreciate that the Sony A77 II (unlike the NX1) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The A77 II is a recent model that features in the current product line-up of Sony. 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 two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Samsung and Sony websites.
So what conclusions can be drawn? Is there a clear favorite between the Samsung NX1 and the Sony A77 II? Which camera is better? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Samsung NX1:
- More detail: Offers more megapixels (28 vs 24MP) with a 8% higher linear resolution.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.

- More heavily discounted: Has been on the market for longer (launched in May 2014).
If the count of relative strengths (bullet points above) is taken as a measure, the NX1 is the clear winner of the match-up (15 : 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 Samsung NX1 and the Sony A77 II 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the NX1 and the A77 II in practical situations. 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 why hands-on reviews by experts 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 assessments were made in relation to similar cameras of the same technological generation. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
