Canon G7 X versus Panasonic TZ100

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

The side-by-side display below illustrates the physical size and weight of the Canon G7 X and the Panasonic TZ100. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter. You can also toggle the display 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 G7X – represents the basis or 100 percent across all the size and weight measures).

The price is, of course, an important factor in any camera decision. 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 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.

 

Sensor comparison: Canon G7 X vs Panasonic TZ100

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 are more costly to manufacture and tend to 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.

Canon G7 X and Panasonic TZ100 sensor measures

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 G7X and the TZ100 have the same pixel density, as well as the same pixel size. It should, however, be noted that the TZ100 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.

G7X versus TZ100 MP

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 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 are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the TZ100 provides a better video resolution than the G7X. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/60p.

 

Feature comparison: Canon G7 X vs Panasonic TZ100

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the TZ100 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 adjacent table lists some of the other core features of the Canon G7 X and Panasonic TZ100 along with similar information for a selection of comparators. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the TZ100 features 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 G7X and the TZ100 have zoom lenses build in. The G7X has a 24-100mm f/1.8-2.8 optic and the TZ100 offers a 25-250mm f/2.8-5.9 (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.

Both the G7X and the TZ100 write their imaging data to SDXC cards.

Review summary: Canon G7 X vs Panasonic TZ100

So what is the bottom line? Is the Canon G7 X better than the Panasonic TZ100 or vice versa? The listing below highlights the relative strengths of the two models.

ilogo

Advantages 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 thus needs less room in the bag.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More heavily discounted: Has been on the market for longer (launched in September 2014).

ilogo

Arguments in favor of the Panasonic Lumix DMC-TZ100:

  • 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.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
  • Longer lasting: Gets more shots (300 versus 210) out of a single battery charge.
  • More modern: Was introduced somewhat (1 year and 3 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the TZ100 comes out slightly ahead of the G7X (7 : 6 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.

G7X 06:07 TZ100

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the G7X and the TZ100 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 why expert reviews are important. The table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, 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.
