Body comparison: Sony RX10 III vs A6300

An illustration of the physical size and weight of the Sony RX10 III and the Sony A6300 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size 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 – the RX10 III – represents the basis or 100 percent 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 A6300 is considerably smaller (36 percent) than the Sony RX10 III. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX10 III has a lens built in, whereas the A6300 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 A6300 and their specifications in the Sony E-Mount Lens Catalog.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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.

Any camera decision will obviously take relative prices into account. 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. 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.

 

Sensor comparison: Sony RX10 III vs A6300

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Sony RX10 III features an one-inch sensor and the Sony A6300 an APS-C sensor. The sensor area in the A6300 is 216 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sony RX10 III and Sony A6300 sensor measures

With 24MP, the A6300 offers a higher resolution than the RX10 III (20MP), but the A6300 nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 2.41μm for the RX10 III) due to its larger sensor. It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation.

The A6300 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during video recording.

The Sony Cyber-shot DSC-RX10 III has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 64-25600. The corresponding ISO settings for the Sony Alpha A6300 are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 100-51200..

RX10 III versus A6300 MP

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 consideration, the A6300 offers substantially better image quality than the RX10 III (overall score 15 points higher). The advantage is based on 1.3 bits higher color depth, 1.1 EV in additional dynamic range, and 1.6 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

One feature that is present on the RX10 III, but is missing on the A6300 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, both cameras feature an 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 RX10 III and the A6300 write their files to SDXC or Memory Stick PRO Duo cards.

The RX10 III is a recent model that features in the current product line-up of Sony. In contrast, the A6300 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the A6300 was succeeded by the Sony A6500.


Review summary: Sony RX10 III vs A6300

So how do things add up? Which of the two cameras – the Sony RX10 III or the Sony A6300 – 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 Cyber-shot DSC-RX10 III:

  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • More detailed LCD: Has a higher resolution rear screen (1229k vs 922k dots).
  • Faster burst: Shoots at higher frequency (14 vs 11 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Has a lens built-in, whereas the A6300 requires a separate lens.
  • Sharper images: Has hand-shake reducing image stabilization built-in.


Advantages of the Sony Alpha A6300:

  • More detail: Has more megapixels (24 vs 20MP), which boosts linear resolution by 10%.
  • Better image quality: Scores substantially higher (15 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.3 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (1.1 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (1.6 stops ISO advantage).
  • Better video autofocus: Features on-sensor phase-detection for more confident movie autofocus.
  • Faster shutter: Has higher mechanical shutter speed (4000/sec vs 2000/sec) to freeze action.
  • More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
  • More compact: Is smaller (120x67mm vs 133x94mm) and will fit more readily into a bag.

If the count of individual advantages (bullet points above) is taken as a guide, the A6300 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.

RX10 III 06:09 A6300

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the RX10 III or the A6300. 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.

The review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
