Sony A5000 vs RX100 IV
The Sony Alpha A5000 and the Sony Cyber-shot DSC-RX100 IV are two digital cameras that were revealed to the public, respectively, in January 2014 and June 2015. The A5000 is a mirrorless interchangeable lens camera, while the RX100 IV is a fixed lens compact. The cameras are based on an APS-C (A5000) and an one-inch (RX100 IV) sensor. The A5000 has a resolution of 19.8 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 A5000 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 physical size and weight of the Sony A5000 and the Sony RX100 IV are illustrated in the side-by-side display below. 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 dimensions are rounded to the nearest millimeter.
The A5000 can be obtained in three different colors (black, silver, white), while the RX100 IV 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 RX100 IV is notably smaller (15 percent) than the Sony A5000. In this context, it is worth noting that neither the A5000 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 A5000 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 A5000 and their specifications in the Sony E-Mount Lens Catalog.
Concerning battery life, the A5000 gets 420 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 battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the 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 A5000 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 slightly higher resolution of 20 megapixels, compared with 19.8 MP of the A5000. 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 4.25μm for the A5000). However, it should be noted that the RX100 IV is a somewhat more recent model (by 1 year and 5 months) than the A5000, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.
The Sony Alpha A5000 has a native sensitivity range from ISO 100 to ISO 16000. 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.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under review, the A5000 has a notably higher overall DXO score than the RX100 IV (overall score 9 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1 bits higher color depth, 0.4 EV in additional dynamic range, and 0.9 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.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the RX100 IV provides a better video resolution than the A5000. It can shoot movie footage at 4K/30p, while the A5000 is limited to 1080/60i.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the RX100 IV has an electronic viewfinder (2359k dots), which can be very helpful when shooting in bright sunlight. In contrast, the A5000 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Sony A5000 and Sony RX100 IV along with similar information for a selection of comparators.

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 A5000 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 A5000 and Sony Cyber-shot DSC-RX100 IV and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the A5000 and the RX100 IV have been discontinued, but can regularly be found used on eBay. The A5000 was replaced by the Sony A5100, 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? Is there a clear favorite between the Sony A5000 and the Sony RX100 IV? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Sony Alpha A5000:
- Better image quality: Scores markedly higher (9 points) in the DXO overall assessment.
- Better low-light sensitivity: Requires less light for good images (0.9 stops ISO advantage).
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
- More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
- Longer lasting: Can take more shots (420 versus 280) on a single battery charge.
- More heavily discounted: Has been on the market for longer (launched in January 2014).
Advantages of the Sony Cyber-shot DSC-RX100 IV:
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60i).
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- More detailed LCD: Has a higher resolution rear screen (1228k vs 461k dots).
- Faster burst: Shoots at higher frequency (16 vs 3.5 flaps/sec) to capture the decisive moment.
- Less disturbing: Has an electronic shutter option for completely silent shooting.
- Ready to shoot: Has an integrated lens, whereas the A5000 necessitates an extra lens.
- More compact: Is smaller (102x58mm vs 110x63mm) and will fit more readily into a bag.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- More modern: Was introduced somewhat (1 year and 5 months) more recently.
If the count of individual advantages (bullet points above) is taken as a guide, the RX100 IV emerges as the winner of the match-up (9 : 6 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. 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 A5000 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the A5000 or the RX100 IV 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 following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], 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 ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
