Sony A6000 versus Sony RX100 IV

The Sony Alpha A6000 and the Sony Cyber-shot DSC-RX100 IV are two digital cameras that were officially introduced, respectively, in February 2014 and June 2015. The A6000 is a mirrorless interchangeable lens camera, while the RX100 IV is a fixed lens compact. The cameras are based on an APS-C (A6000) and an one-inch sensor. The A6000 has a resolution of 24 megapixel, whereas the RX100 IV provides 20 MP.

Body comparison

The physical size and weight of the Sony A6000 and the Sony RX100 IV are illustrated in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth dimensions are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the A6000 – represents the basis or 100 percent across all the size and weight measures).

Body view (A6000 on the left)

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 A6000. Cameras that are aimed at professionals or semi-pros tend to be a bit bulkier in order to give them the necessary environmental and shock resistance. In this context, it is worth noting that neither the A6000 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 build in, whereas the A6000 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can find an overview of optics for the A6000 and their specifications in the Sony E-Mount Lens Catalog.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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. 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 are more costly to manufacture and tent to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Sony A6000 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.

Sensor size

With 24MP, the A6000 offers a higher resolution than the RX100 IV (20MP), but the A6000 nevertheless has larger individual pixels (pixel pitch of 3.92μm versus 2.41μm for the RX100 IV) due to its larger sensor. However, the RX100 IV is a somewhat more recent model (by 1 year and 3 months) than the A6000, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.

Sensor resolution

For most cameras, data on sensor performance has been reported by DXO Mark. 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 A6000 provides substantially higher image quality than the RX100 IV, with an overall score that is 12 points higher. This advantage is based on 1.3 bits higher color depth, 0.5 EV in additional dynamic range, and 1.2 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the RX100 IV provides a better video resolution than the A6000. It can shoot movie footage at 4K/30p, while the A6000 is limited to 1080/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the RX100 IV offers a substantially higher resolution than the one in the A6000 (2359k vs 1440k dots). The adjacent table lists some of the other core features of the Sony A6000 and Sony RX100 IV along with similar information for a selection of comparators. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Both the A6000 and the RX100 IV have been discontinued, but can regularly be found used on ebay. The A6000 was replaced by the Sony A6300, while the RX100 IV was followed by the Sony RX100 V.

Summary

So how do things add up? Which of the two cameras – the Sony A6000 or the Sony RX100 IV – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.


Arguments in favor of the Sony Alpha A6000:

  • More detail: Offers more megapixels (24 vs 20MP) with a 10% higher linear resolution.
  • Better image quality: Scores substantially higher (12 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (1.3 bits more color depth).
  • Better low-light sensitivity: Requires less light for good images (1.2 stops ISO advantage).
  • Faster shutter: Has a higher mechanical shutter speed (4000/sec vs 2000/sec) to freeze action.
  • More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
  • Longer lasting: Can take more shots (360 versus 280) on a single battery charge.
  • More heavily discounted: Has been on the market for longer (launched in February 2014).

Reasons to prefer the Sony Cyber-shot DSC-RX100 IV:

  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • More detailed viewfinder: Has a higher resolution electronic viewfinder (2359k vs 1440k dots).
  • More detailed LCD: Has a higher resolution rear screen (1228k vs 922k dots).
  • Faster burst: Shoots at higher frequency (16 vs 11 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Has an integrated lens, whereas the A6000 necessitates an extra lens.
  • More compact: Is smaller (102x58mm vs 120x67mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight even though it has a lens build in (unlike the A6000).
  • More modern: Was introduced somewhat (1 year and 3 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the match-up finishes in a tie (8 points each). 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.

A6000 08:08 RX100 IV

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 A6000 or the RX100 IV handle or perform in practice. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate. This is why hands-on reviews by experts are important. The table below summarizes the assessments of some of the best known camera review sites. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when refering to cameras in the same category and of the same age. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
