Panasonic ZS100 versus Canon G7 X

The Panasonic Lumix DMC-ZS100 (called Panasonic TZ100 in some regions) and the Canon PowerShot G7 X are two digital cameras that were officially introduced, respectively, in January 2016 and September 2014. Both the ZS100 and the G7X are fixed lens compact cameras that are equipped with an one-inch sensor. Both cameras offer a resolution of 20 megapixel.

Body comparison

The physical size and weight of the Panasonic ZS100 and the Canon G7 X are illustrated in the side-by-side display below. Three successive views from the front, the top, and the rear 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 – 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 Canon G7 X is notably smaller (14 percent) than the Panasonic ZS100. Moreover, the G7X is slightly lighter (3 percent) than the ZS100. In this context, it is worth noting that neither the ZS100 nor the G7X 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 two cameras under review were launched at the same price and fall into the same 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.

Sensor comparison

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. 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 associated with larger, more expensive camera bodies 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.

Sensor size

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 G7X 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 1 year and 3 months) than the G7X, and its sensor might have benefitted from technological advances during this time.

Sensor resolution

For most cameras, data on sensor performance has been reported by DXO Mark. 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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the ZS100 provides a higher video resolution than the G7X. It can shoot video footage at 4K/30p, while the Canon is limited to 1080/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the ZS100 has an electronic viewfinder (1166k dots), which can be very helpful when shooting in bright sunlight. In contrast, the G7X relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Panasonic ZS100, the Canon G7 X, and comparable cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

Both the ZS100 and the G7X have zoom lenses build in. The ZS100 has a 25-250mm f/2.8-5.9 optic and the G7X offers a 24-100mm f/1.8-2.8 (focal lengths in full frame equivalent terms). Hence, the Canon provides a wider angle of view at the short end than the Panasonic, but less tele-photo reach at the long end. The G7X offers the faster maximum aperture.

The ZS100 is a current model that online retailers, such as amazon, will have in stock. In contrast, the G7X has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the G7X was succeeded by the Canon G7 X Mark II.

Summary

So how do things add up? Which of the two cameras – the Panasonic ZS100 or the Canon G7 X – has the upper hand? The listing below highlights the relative strengths of the two models.


logo checkmark

Reasons to prefer the Panasonic Lumix DMC-ZS100:

  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • Easier framing: Has an electronic viewfinder for image framing and settings control.
  • Faster burst: Shoots at higher frequency (10 vs 6.5 flaps/sec) to capture the decisive moment.
  • More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
  • Longer lasting: Can take more shots (300 versus 210) on a single battery charge.
  • Sharper images: Has hand-shake reducing image stabilization build-in.
  • More modern: Is somewhat more recent (announced 1 year and 3 months after the G7X).

logo checkmark

Arguments in favor of the Canon PowerShot G7 X:

  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • 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 (103x60mm vs 111x65mm) and will fit more readily into a bag.
  • More heavily discounted: Has been on the market for longer (launched in September 2014).

If the count of relative strengths (bullet points above) is taken as a measure, the ZS100 emerges as the winner of the contest (7 : 5 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.

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 G7X in practical situations. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable. This is where reviews by experts come in. The adjacent table relays the overall verdicts of several of the most popular camera review sites. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
