Any camera decision will obviously take relative prices into account. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The RX10 II was launched at a somewhat lower price (by 24 percent) than the RX10 IV, which makes it more attractive for photographers on a tight budget. 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.
The size of the imaging sensor is a crucial determinant 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Both cameras under consideration feature an one-inch sensor and have a format factor (sometimes also referred to as "crop factor") of 2.7. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 20 megapixels. This similarity in sensor specs implies that both the RX10 II and the RX10 IV have the same pixel density, as well as the same pixel size. It should, however, be noted that the RX10 IV is much more recent (by 2 years and 3 months) than the RX10 II, and its sensor will have benefitted from technological advances during this time.
The RX10 IV has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Sony Cyber-shot DSC-RX10 II has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 64-25600. The Sony Cyber-shot DSC-RX10 IV offers exactly the same ISO settings.
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"). 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (4K/30p).
Apart from body and sensor, cameras can and do differ across a range of features. The RX10 II and the RX10 IV are similar in the sense that both feature an electronic viewfinder, which is helpful when framing images in bright sunlight. Moreover, their viewfinders offer an identical resolution of 2359k dots. The table below summarizes some of the other core capabilities of the Sony RX10 II and Sony RX10 IV in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The RX10 IV has a touchscreen, while the RX10 II has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
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, both cameras under consideration 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).
Both the RX10 II and the RX10 IV have zoom lenses built in. The RX10 II has a 24-200mm f/2.8-2.8 optic and the RX10 IV offers a 24-600mm f/2.4-4.0 (focal lengths in full frame equivalent terms). Hence, the RX10 II and RX10 IV provide the same view at the wide-angle end, but the RX10 IV has more tele-photo reach at the long end. The RX10 IV offers the faster maximum aperture.
Concerning the storage of imaging data, both the RX10 II and the RX10 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 Cyber-shot DSC-RX10 II and Sony Cyber-shot DSC-RX10 IV and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

The RX10 IV is a recent model that features in the current product line-up of Sony. In contrast, the RX10 II has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the RX10 II was succeeded by the Sony RX10 III. 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 what is the bottom line? Is there a clear favorite between the Sony RX10 II and the Sony RX10 IV? Which camera is better? The listing below highlights the relative strengths of the two models.
Advantages of the Sony Cyber-shot DSC-RX10 II:
- Faster shutter: Has higher mechanical shutter speed (1/3200s vs 1/2000s) to freeze action.
- Less heavy: Is lighter (by 282g or 26 percent) and hence easier to carry around.
- More affordable: Was introduced into a lower priced segment (24 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in June 2015).
Reasons to prefer the Sony Cyber-shot DSC-RX10 IV:
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- More detailed LCD: Has a higher resolution rear screen (1440k vs 1229k dots).
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- Faster burst: Shoots at higher frequency (24 vs 14 flaps/sec) to capture the decisive moment.
- Better light gathering: Has a lens with a wider maximum aperture (f/2.4 vs f/2.8).
- More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
- More modern: Reflects 2 years and 3 months of technical progress since the RX10 II launch.
If the count of individual advantages (bullet points above) is taken as a guide, the RX10 IV emerges as the winner of the match-up (7 : 4 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. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

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 RX10 II or the RX10 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 where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
