Panasonic ZS100 versus Panasonic LX100

The Panasonic Lumix DMC-ZS100 (called Panasonic TZ100 in some regions) and the Panasonic Lumix DMC-LX100 are two digital cameras that were officially introduced, respectively, in January 2016 and September 2014. Both the ZS100 and the LX100 are fixed lens compact cameras that are based on an one-inch (ZS100) and a Four Thirds (LX100) sensor. The ZS100 has a resolution of 20 megapixel, whereas the LX100 provides 12.7 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: Panasonic ZS100 vs Panasonic LX100

The side-by-side display below illustrates the physical size and weight of the Panasonic ZS100 and the Panasonic LX100. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth dimensions 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 – the ZS100 – 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 Panasonic LX100 is notably larger (5 percent) than the Panasonic ZS100. Moreover, the LX100 is markedly heavier (26 percent) than the ZS100. In this context, it is worth noting that neither the ZS100 nor the LX100 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.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The ZS100 was launched at a somewhat lower price (by 22 percent) than the LX100, which makes it more attractive for photographers on a tight budget. 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.


Sensor comparison: Panasonic ZS100 vs Panasonic LX100

The size of the imaging sensor is a crucial determinant of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 Panasonic ZS100 features an one-inch sensor and the Panasonic LX100 a Four Thirds sensor. The sensor area in the LX100 is 94 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 2.0. The sensor in the ZS100 has a native 3:2 aspect ratio, while the one in the LX100 offers a 4:3 aspect.

Panasonic ZS100 and Panasonic LX100 sensor measures
Sensor size

Despite having a smaller sensor, the Panasonic ZS100 offers a higher resolution of 20 megapixel, compared with 12.7 MP of the Panasonic LX100. This megapixel 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 4.21μm for the LX100). However, it should be noted that the ZS100 is a somewhat more recent model (by 1 year and 3 months) than the LX100, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.

Both the ZS100 and the LX100 have zoom lenses build in. The ZS100 has a 25-250mm f/2.8-5.9 optic and the LX100 offers a 24-75mm f/1.7-2.8 (focal lengths in full frame equivalent terms). Hence, the LX100 provides a wider angle of view at the short end than the ZS100, but less tele-photo reach at the long end. The LX100 offers the faster maximum aperture.

The LX100 is a current model that online retailers, such as amazon, will have in stock. In contrast, the ZS100 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the ZS100 was succeeded by the Panasonic ZS200.

Review summary: Panasonic ZS100 vs Panasonic LX100

So what conclusions can be drawn? Is the Panasonic ZS100 better than the Panasonic LX100 or vice versa? Below is a summary of the relative strengths of each of the two contestants.


Arguments in favor of the Panasonic Lumix DMC-ZS100:

  • More detail: Offers more megapixels (20 vs 12.7MP) with a 28% higher linear resolution.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 921k dots).
  • 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.
  • Less heavy: Is lighter (by 81g or 21 percent) and hence easier to carry around.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More affordable: Was introduced into a lower priced segment (22 percent cheaper at launch).

If the count of individual advantages (bullet points above) is taken as a guide, the ZS100 emerges as the winner of the contest (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 before making a decision on a new camera.

ZS100 08:05 LX100

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 LX100 in practical situations. 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 expert reviews are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites.

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. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
