Panasonic GX800 vs TZ100
The Panasonic Lumix DMC-GX800 (called Panasonic GX850 in some regions) and the Panasonic Lumix DMC-TZ100 (labelled Panasonic ZS100 in some countries) are two digital cameras that were revealed to the public, respectively, in January 2017 and January 2016. The GX800 is a mirrorless interchangeable lens camera, while the TZ100 is a fixed lens compact. The cameras are based on a Four Thirds (GX800) and an one-inch (TZ100) sensor. The GX800 has a resolution of 15.8 megapixels, whereas the TZ100 provides 20 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-GX800 and the Panasonic Lumix DMC-TZ100? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
The physical size and weight of the Panasonic GX800 and the Panasonic TZ100 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. 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.
The GX800 can be obtained in three different colors (black, silver, red), while the TZ100 is available in two color-versions (black, silver).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic TZ100 is somewhat larger (4 percent) than the Panasonic GX800. In this context, it is worth noting that neither the GX800 nor the TZ100 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the TZ100 has a lens built in, whereas the GX800 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the GX800 and their specifications in the Micro Four Thirds Lens Catalog.
Concerning battery life, the GX800 gets 210 shots out of its DMW-BLH7 battery, while the TZ100 can take 300 images on a single charge of its DMW-BLG10 power pack. The power pack in the TZ100 can be charged via the USB port, which can be very convenient when travelling.

Any camera decision will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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.
The size of the imaging sensor is a crucial determinant 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Panasonic GX800 features a Four Thirds sensor and the Panasonic TZ100 an one-inch sensor. The sensor area in the TZ100 is 48 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 2.7. The sensor in the GX800 has a native 4:3 aspect ratio, while the one in the TZ100 offers a 3:2 aspect.
Despite having a smaller sensor, the TZ100 offers a higher resolution of 20 megapixels, compared with 15.8 MP of the GX800. This megapixels 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 3.77μm for the GX800). Moreover, it should be noted that the GX800 is a somewhat more recent model (by 1 year) than the TZ100, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the GX800 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Panasonic TZ100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the TZ100 for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inch or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inch or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inch or 46.3 x 30.9 cm. The corresponding values for the Panasonic GX800 are 23 x 17.2 inch or 58.3 x 43.8 cm for good quality, 18.4 x 13.8 inch or 46.7 x 35 cm for very good quality, and 15.3 x 11.5 inch or 38.9 x 29.2 cm for excellent quality prints.
The Panasonic Lumix DMC-GX800 has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600. The corresponding ISO settings for the Panasonic Lumix DMC-TZ100 are ISO 125 to ISO 12800, with the possibility to increase the ISO range to 80-25600.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. 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 are not only capable of taking still images, but can also record movies. 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).
Beyond body and sensor, cameras can and do differ across a range 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 GX800 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Panasonic GX800 and Panasonic TZ100 along with similar information for a selection of comparators.

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).
The Panasonic GX800 and the Panasonic TZ100 both have an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
Concerning the storage of imaging data, both the GX800 and the TZ100 write their files to SDXC 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 Panasonic Lumix DMC-GX800 and Panasonic Lumix DMC-TZ100 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

The GX800 is a recent model that features in the current product line-up of Panasonic. In contrast, the TZ100 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the TZ100 was succeeded by the Panasonic TZ200. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Panasonic website.
So what conclusions can be drawn? Is the Panasonic GX800 better than the Panasonic TZ100 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Panasonic Lumix DMC-GX800:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- More dynamic range: Captures a larger spectrum of light and dark details (0.8 EV of extra DR).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
- More modern: Is somewhat more recent (announced 1 year after the TZ100).
Arguments in favor of the Panasonic Lumix DMC-TZ100:
- More detail: Has more megapixels (20 vs 15.8MP), which boosts linear resolution by 15%.
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- Faster shutter: Has higher mechanical shutter speed (1/2000s vs 1/500s) to freeze action.
- Ready to shoot: Has an integrated lens, whereas the GX800 necessitates an extra lens.
- Longer lasting: Gets more shots (300 versus 210) out of a single battery charge.
- Easier travel charging: Can be conveniently charged via its USB port.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- More heavily discounted: Has been on the market for longer (launched in January 2016).
If the count of individual advantages (bullet points above) is taken as a guide, the TZ100 emerges as the winner of the match-up (8 : 6 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
How about other alternatives? Do the specifications of the Panasonic GX800 and the Panasonic TZ100 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Superzoom Camera listings whether the two cameras rank among the cream of the crop.
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 GX800 or the TZ100 perform in practice. 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 why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major 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.
The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
