Sony A5100 vs NEX-6
The Sony Alpha A5100 and the Sony Alpha NEX-6 are two digital cameras that were officially introduced, respectively, in August 2014 and September 2012. Both the A5100 and the NEX-6 are mirrorless interchangeable lens cameras that are equipped with an APS-C sensor. The A5100 has a resolution of 24 megapixels, whereas the NEX-6 provides 16 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 Sony Alpha A5100 and the Sony Alpha NEX-6? 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.
The side-by-side display below illustrates the physical size and weight of the Sony A5100 and the Sony NEX-6. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.
The A5100 can be obtained in two different colors (black, white), while the NEX-6 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 Sony NEX-6 is notably larger (16 percent) than the Sony A5100. Moreover, the NEX-6 is markedly heavier (22 percent) than the A5100. In this context, it is worth noting that neither the A5100 nor the NEX-6 are weather-sealed.
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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Sony E-Mount Lens Catalog. Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.
The power pack in the A5100 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 A5100 was launched at a markedly lower price (by 45 percent) than the NEX-6, 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.
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. 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 NEX-6 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 24MP, the A5100 offers a higher resolution than the NEX-6 (16MP), but the A5100 has smaller individual pixels (pixel pitch of 3.91μm versus 4.78μm for the NEX-6). However, the A5100 is a somewhat more recent model (by 1 year and 11 months) than the NEX-6, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.
The resolution advantage of the Sony A5100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A5100 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Sony NEX-6 are 24.6 x 16.3 inches or 62.4 x 41.5 cm for good quality, 19.6 x 13.1 inches or 49.9 x 33.2 cm for very good quality, and 16.4 x 10.9 inches or 41.6 x 27.6 cm for excellent quality prints.
The A5100 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Sony Alpha A5100 has a native sensitivity range from ISO 100 to ISO 25600. The Sony Alpha NEX-6 offers exactly the same ISO settings.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. 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 also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the A5100 provides a higher frame rate than the NEX-6. It can shoot video footage at 1080/60p, while the NEX-6 is limited to 1080/60i.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the NEX-6 has an electronic viewfinder (2359k dots), which can be very helpful when shooting in bright sunlight. In contrast, the A5100 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Sony A5100 and Sony NEX-6 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 A5100 has a touchscreen, while the NEX-6 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The A5100 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 NEX-6 does not have a selfie-screen.
Concerning the storage of imaging data, both the A5100 and the NEX-6 write their files to SDXC or Memory Stick PRO Duo cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
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 Sony Alpha A5100 and Sony Alpha NEX-6 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the NEX-6 has a hotshoe, which makes it possible to easily attach optional accessories, such as an external flash gun. The A5100 does not feature such an accessory-socket.
The A5100 is a recent model that features in the current product line-up of Sony. In contrast, the NEX-6 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the NEX-6 was succeeded by the Sony A6000. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Sony website.
So how do things add up? Is there a clear favorite between the Sony A5100 and the Sony NEX-6? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Sony Alpha A5100:
- More detail: Offers more megapixels (24 vs 16MP) with a 22% higher linear resolution.
- Better low-light sensitivity: Requires less light for good images (0.4 stops ISO advantage).
- Better video: Provides higher movie framerates (1080/60p versus 1080/60i).
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- More compact: Is smaller (110x63mm vs 120x67mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 62g or 18 percent) and hence easier to carry around.
- Longer lasting: Can take more shots (400 versus 360) on a single battery charge.
- Easier travel charging: Can be conveniently charged via its USB port.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
- More affordable: Was introduced into a lower priced category (45 percent cheaper at launch).
- More modern: Is somewhat more recent (announced 1 year and 11 months after the NEX-6).
Arguments in favor of the Sony Alpha NEX-6:
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- Faster burst: Shoots at higher frequency (10 vs 6 flaps/sec) to capture the decisive moment.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- More heavily discounted: Has been on the market for longer (launched in September 2012).
If the count of individual advantages (bullet points above) is taken as a guide, the A5100 is the clear winner of the match-up (13 : 4 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 Sony A5100 and the Sony NEX-6 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing 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 A5100 and the NEX-6 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 (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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
