Sony NEX-6 vs RX100 IV
The Sony Alpha NEX-6 and the Sony Cyber-shot DSC-RX100 IV are two digital cameras that were announced, respectively, in September 2012 and June 2015. The NEX-6 is a mirrorless interchangeable lens camera, while the RX100 IV is a fixed lens compact. The cameras are based on an APS-C (NEX-6) and an one-inch (RX100 IV) sensor. The NEX-6 has a resolution of 16 megapixels, whereas the RX100 IV provides 20 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 NEX-6 and the Sony Cyber-shot DSC-RX100 IV? 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 NEX-6 and the Sony RX100 IV. 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony RX100 IV is notably smaller (26 percent) than the Sony NEX-6. In this context, it is worth noting that neither the NEX-6 nor the RX100 IV are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX100 IV has a lens built in, whereas the NEX-6 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 NEX-6 and their specifications in the Sony E-Mount Lens Catalog.
Concerning battery life, the NEX-6 gets 360 shots out of its NP-FW50 battery, while the RX100 IV can take 280 images on a single charge of its NP-BX1 power pack. The power pack in the RX100 IV can be charged via the USB port, which can be very convenient 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. 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.
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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Sony NEX-6 features an APS-C sensor and the Sony RX100 IV an one-inch sensor. The sensor area in the RX100 IV is 68 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.7. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Despite having a smaller sensor, the RX100 IV offers a higher resolution of 20 megapixels, compared with 16 MP of the NEX-6. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 2.41μm versus 4.78μm for the NEX-6). However, it should be noted that the RX100 IV is much more recent (by 2 years and 8 months) than the NEX-6, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The resolution advantage of the Sony RX100 IV implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX100 IV for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 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 Sony Alpha NEX-6 has a native sensitivity range from ISO 100 to ISO 25600. The corresponding ISO settings for the Sony Cyber-shot DSC-RX100 IV are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 80-25600.
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. Of the two cameras under review, the NEX-6 has a notably higher overall DXO score than the RX100 IV (overall score 8 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.9 bits higher color depth, 0.5 EV in additional dynamic range, and 0.8 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.
|Sony RX100 IV||1-inch||20.0||5472||3648||4K/30p||22.8||12.6||591||70|

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the RX100 IV provides a better video resolution than the NEX-6. It can shoot movie footage at 4K/30p, while the NEX-6 is limited to 1080/60i.
Apart from body and sensor, cameras can and do differ across a range of features. The NEX-6 and the RX100 IV are similar in the sense that both feature an electronic viewfinder, which is helpful when framing images in bright sunlight. Moreover, their viewfinders offer an identical resolution of 2359k dots. The following table reports on some other key feature differences and similarities of the Sony NEX-6, the Sony RX100 IV, and comparable cameras.

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 RX100 IV 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).
Concerning the storage of imaging data, both the NEX-6 and the RX100 IV 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 NEX-6 and Sony Cyber-shot DSC-RX100 IV 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, while the RX100 IV does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Both the NEX-6 and the RX100 IV have been discontinued, but can regularly be found used on eBay. The NEX-6 was replaced by the Sony A6000, while the RX100 IV was followed by the Sony RX100 IV. 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? Which of the two cameras – the Sony NEX-6 or the Sony RX100 IV – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Sony Alpha NEX-6:
- Better image quality: Scores markedly higher (8 points) in the DXO overall assessment.
- Better low-light sensitivity: Requires less light for good images (0.8 stops ISO advantage).

If the count of relative strengths (bullet points above) is taken as a measure, the RX100 IV is the clear winner of the contest (12 : 8 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 Sony NEX-6 and the Sony RX100 IV place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Travel-Zoom 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 NEX-6 or the RX100 IV perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major 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.

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 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.
