Panasonic ZS100 versus Sony RX100 IV
The Panasonic Lumix DMC-ZS100 (called Panasonic TZ100 in some regions) and the Sony Cyber-shot DSC-RX100 IV are two digital cameras that were revealed to the public, respectively, in January 2016 and June 2015. Both the ZS100 and the RX100 IV are fixed lens compact cameras that are equipped with an one-inch sensor. Both cameras offer a resolution of 20 megapixel.
An illustration of the physical size and weight of the Panasonic ZS100 and the Sony RX100 IV is provided in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All size dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left side – the ZS100 – 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 RX100 IV is notably smaller (18 percent) than the Panasonic ZS100. Moreover, the RX100 IV is slightly lighter (4 percent) than the ZS100. In this context, it is worth noting that neither the ZS100 nor the RX100 IV are weather-sealed.
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 comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The ZS100 was launched at a markedly lower price (by 30 percent) than the RX100 IV, which puts it into a different market segment. 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.
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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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 megapixel. This similarity in sensor specs implies that both the ZS100 and the RX100 IV have the same pixel density, as well as the same pixel size. It should, however, be noted that the ZS100 is a somewhat more recent model (by 6 months) than the RX100 IV, and its sensor might have benefitted from technological advances during this time.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (4K/30p).
Beyond 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 RX100 IV offers a substantially higher resolution than the one in the ZS100 (2359k vs 1166k dots). The table below summarizes some of the other core capabilities of the Panasonic ZS100 and Sony RX100 IV in connection with corresponding information for a sample of similar cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

Both the ZS100 and the RX100 IV have zoom lenses build in. The ZS100 has a 25-250mm f/2.8-5.9 optic and the RX100 IV offers a 24-70mm f/1.8-2.8 (focal lengths in full frame equivalent terms). Hence, the Sony provides a wider angle of view at the short end than the Panasonic, but less tele-photo reach at the long end. The RX100 IV offers the faster maximum aperture.
The ZS100 is a current model that online retailers, such as amazon, will have in stock. In contrast, the RX100 IV has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the RX100 IV was succeeded by the Sony RX100 V.
So how do things add up? Is there a clear favorite between the Panasonic ZS100 and the Panasonic ZS100? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Panasonic Lumix DMC-ZS100:
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
- Sharper images: Has hand-shake reducing image stabilization build-in.
- More affordable: Was introduced into a lower priced category (30 percent cheaper at launch).
- More modern: Is somewhat more recent (announced 6 months after the RX100 IV).
Reasons to prefer the Sony Cyber-shot DSC-RX100 IV:
- More detailed viewfinder: Has higher resolution electronic viewfinder (2359k vs 1166k dots).
- More detailed LCD: Has a higher resolution rear screen (1228k vs 1040k dots).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Faster burst: Shoots at higher frequency (16 vs 10 flaps/sec) to capture the decisive moment.
- Better light gathering: Has a lens with a wider maximum aperture (f/1.8 vs f/2.8).
- Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
- More compact: Is smaller (102x58mm vs 111x65mm) and will fit more readily into a bag.
- More heavily discounted: Has been on the market for longer (launched in June 2015).
If the count of relative strengths (bullet points above) is taken as a measure, the RX100 IV emerges as the winner of the match-up (8 : 5 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the ZS100 and the RX100 IV in practical situations. 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. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The above review scores should be interpreted with care, 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.
In case you would like to check on the differences and similarities of other camera models, just make your choice using the following search menu. There is also a set of direct links to comparison reviews that other users of the CAM-parator app explored. If the camera you are interested in is not available, please contact me, and I will try to add information on that model to the database.
