Sony RX10 IV versus Sony A6500

The Sony Cyber-shot DSC-RX10 IV and the Sony Alpha A6500 are two enthusiast cameras that were revealed to the public, respectively, in September 2017 and October 2016. The RX10 IV is a fixed lens compact, while the A6500 is a mirrorless interchangeable lens camera. The cameras are based on an one-inch (RX10 IV) and an APS-C (A6500) sensor. The RX10 IV has a resolution of 20 megapixel, whereas the A6500 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 RX10 IV vs Sony A6500

The side-by-side display below illustrates the physical size and weight of the Sony RX10 IV and the Sony A6500. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth measures 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 side – the RX10 IV – 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 A6500 is considerably smaller (36 percent) than the Sony RX10 IV. 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 IV has a lens build in, whereas the A6500 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 A6500 and their specifications in the Sony E-Mount Lens Catalog.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 purchase will naturally be influenced heavily by the price. The listed launch 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.

 

Sensor comparison: Sony RX10 IV vs Sony A6500

The size of the imaging sensor is a crucial determinant 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 tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Sony RX10 IV features an one-inch sensor and the Sony A6500 an APS-C sensor. The sensor area in the A6500 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 IV and Sony A6500 sensor measures

With 24MP, the A6500 offers a higher resolution than the RX10 IV (20MP), but the A6500 nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 2.41μm for the RX10 IV) due to its larger sensor. However, the RX10 IV is a somewhat more recent model (by 11 months) than the A6500, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

One feature that is present on the RX10 IV, but is missing on the A6500 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 (rolling shutter) or shooting under artificial light sources (flickering).

Both the RX10 IV and the A6500 write their imaging data to SDXC or Memory Stick PRO Duo cards.

  • Ready to shoot: Has a lens build-in, whereas the A6500 requires a separate lens.
  • Longer lasting: Can take more shots (400 versus 350) on a single battery charge.
  • More modern: Is somewhat more recent (announced 11 months after the A6500).


Reasons to prefer the Sony Alpha A6500:

  • More detail: Has more megapixels (24 vs 20MP), which boosts linear resolution by 10%.
  • Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
  • Richer colors: Larger pixels generate images with better, more accurate colors.
  • More dynamic range: Capable of capturing a wider spectrum of light and dark details.
  • Better low-light sensitivity: Can be used in poorly lit environments and still produce good images.
  • 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.
  • More heavily discounted: Has been on the market for longer (launched in October 2016).

If the number of relative strengths (bullet points above) is taken as a guide, the A6500 emerges as the winner of the match-up (9 : 7 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.

RX10 IV 07:09 A6500

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the RX10 IV or the A6500. 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 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 (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
