Sony RX100 V versus Sony A7

The Sony Cyber-shot DSC-RX100 V and the Sony Alpha A7 are two digital cameras that were announced, respectively, in October 2016 and October 2013. The RX100 V is a fixed lens compact, while the A7 is a mirrorless interchangeable lens camera. The cameras are based on an one-inch (RX100 V) and a full frame (A7) sensor. The RX100 V has a resolution of 20 megapixel, whereas the A7 provides 24 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Sony RX100 V vs Sony A7

The side-by-side display below illustrates the physical size and weight of the Sony RX100 V and the Sony A7. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth dimensions are rounded to the nearest millimeter. You can also toggle the display 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 side – the RX100 V – represents the basis for the calculations across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A7 is considerably larger (102 percent) than the Sony RX100 V. It is noteworthy in this context that the A7 is splash and dust-proof, while the RX100 V does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX100 V has a lens build in, whereas the A7 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 A7 and their specifications in the Sony FE Lens Catalog.

Concerning battery life, the RX100 V gets 220 shots out of its NP-BX1 battery, while the A7 can take 340 images on a single charge of its NP-FW50 power pack.

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 camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The RX100 V was launched at a lower price than the A7, despite having a lens build in. 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: Sony RX100 V vs Sony A7

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. 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 tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Sony RX100 V features an one-inch sensor and the Sony A7 a full frame sensor. The sensor area in the A7 is 638 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sensor size

With 24MP, the A7 offers a higher resolution than the RX100 V (20MP), but the A7 nevertheless has larger individual pixels (pixel pitch of 5.97μm versus 2.41μm for the RX100 V) due to its larger sensor. However, the RX100 V is a much more recent model (by 2 years and 11 months) than the A7, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

Sensor resolution

For most 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"). Of the two cameras under consideration, the A7 offers substantially better image quality than the RX100 V (overall score 20 points higher). The advantage is based on 2 bits higher color depth, 1.8 EV in additional dynamic range, and 1.9 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 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 V provides a higher video resolution than the A7. It can shoot video footage at 4K/30p, while the A7 is limited to 1080/60p.

Feature comparison: Sony RX100 V vs Sony A7

Apart from 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 A7 offers a slightly higher resolution than the one in the RX100 V (2400k vs 2359k dots). The adjacent table lists some of the other core features of the Sony RX100 V and Sony A7 along with similar information for a selection of comparators.

The RX100 V is a current model that online retailers, such as amazon, will have in stock. In contrast, the A7 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the A7 was succeeded by the Sony A7 II.

Review summary: Sony RX100 V vs Sony A7

So what is the bottom line? Which of the two cameras – the Sony RX100 V or the Sony A7 – has the upper hand? The listing below highlights the relative strengths of the two models.


Arguments in favor of the Sony Cyber-shot DSC-RX100 V:

  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • Faster burst: Shoots at higher frequency (24 vs 5 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Has a lens build-in, whereas the A7 requires a separate lens.
  • More compact: Is smaller (102x58mm vs 127x94mm) and thus needs less room in the bag.
  • Less heavy: Is lighter even though it comes with a build-in lens (unlike the A7).
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • Sharper images: Has hand-shake reducing image stabilization build-in.
  • More affordable: Was introduced at a lower price, despite coming with a build-in lens.
  • More modern: Reflects 2 years and 11 months of technical progress since the A7 launch.

Advantages of the Sony Alpha A7:

  • More detail: Has more megapixels (24 vs 20MP), which boosts linear resolution by 10%.
  • Better image quality: Scores substantially higher (20 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (2 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (1.8 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (1.9 stops ISO advantage).
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 2000/sec) to freeze action.
  • More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
  • Longer lasting: Gets more shots (340 versus 220) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • More heavily discounted: Has been around for much longer (launched in October 2013).

If the number of relative strengths (bullet points above) is taken as a guide, the A7 comes out slightly ahead of the RX100 V (10 : 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.

RX100 V 09:10 A7

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the RX100 V and the A7 in practical situations. 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 where reviews by experts come in. The following table reports the overall rankings of the cameras as published by some of the major 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 assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
