Panasonic GM1 vs TZ200
The Panasonic Lumix DMC-GM1 and the Panasonic Lumix DC-TZ200 (labelled Panasonic ZS200 in some countries) are two digital cameras that were officially introduced, respectively, in October 2013 and February 2018. The GM1 is a mirrorless interchangeable lens camera, while the TZ200 is a fixed lens compact. The cameras are based on a Four Thirds (GM1) and an one-inch (TZ200) sensor. The GM1 has a resolution of 15.8 megapixels, whereas the TZ200 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-GM1 and the Panasonic Lumix DC-TZ200? 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.
An illustration of the physical size and weight of the Panasonic GM1 and the Panasonic TZ200 is provided 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 size dimensions are rounded to the nearest millimeter.
The GM1 can be obtained in three different colors (black, silver, red), while the TZ200 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 TZ200 is notably larger (33 percent) than the Panasonic GM1. In this context, it is worth noting that neither the GM1 nor the TZ200 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the TZ200 has a lens built in, whereas the GM1 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 GM1 and their specifications in the Micro Four Thirds Lens Catalog.
Concerning battery life, the GM1 gets 230 shots out of its DMW-BLH7 battery, while the TZ200 can take 370 images on a single charge of its DMW-BLG10 power pack. The power pack in the TZ200 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 listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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. 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Panasonic GM1 features a Four Thirds sensor and the Panasonic TZ200 an one-inch sensor. The sensor area in the TZ200 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 GM1 has a native 4:3 aspect ratio, while the one in the TZ200 offers a 3:2 aspect.
Despite having a smaller sensor, the TZ200 offers a higher resolution of 20 megapixels, compared with 15.8 MP of the GM1. 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 GM1). However, it should be noted that the TZ200 is much more recent (by 4 years and 3 months) than the GM1, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The resolution advantage of the Panasonic TZ200 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the TZ200 for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Panasonic GM1 are 23 x 17.2 inches or 58.3 x 43.8 cm for good quality, 18.4 x 13.8 inches or 46.7 x 35 cm for very good quality, and 15.3 x 11.5 inches or 38.9 x 29.2 cm for excellent quality prints.
The Panasonic Lumix DMC-GM1 has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 125-25600. The corresponding ISO settings for the Panasonic Lumix DC-TZ200 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 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 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 have a sensor with sufficiently fast read-out times for moving pictures, but the TZ200 provides a better video resolution than the GM1. It can shoot movie footage at 4K/30p, while the GM1 is limited to 1080/60i.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the TZ200 has an electronic viewfinder (2330k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GM1 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Panasonic GM1 and Panasonic TZ200 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 GM1 and the Panasonic TZ200 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 GM1 and the TZ200 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-GM1 and Panasonic Lumix DC-TZ200 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

The TZ200 is a recent model that features in the current product line-up of Panasonic. In contrast, the GM1 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the GM1 was succeeded by the Panasonic GM5. 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 there a clear favorite between the Panasonic GM1 and the Panasonic TZ200? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Panasonic Lumix DMC-GM1:
- More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
- More compact: Is smaller (99x55mm vs 111x65mm) and thus needs less room in the bag.
- More heavily discounted: Has been available for much longer (launched in October 2013).
Arguments in favor of the Panasonic Lumix DC-TZ200:
- More detail: Has more megapixels (20 vs 15.8MP), which boosts linear resolution by 15%.
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60i).
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- More detailed LCD: Has a higher resolution rear screen (1240k vs 1036k dots).
- Faster shutter: Has higher mechanical shutter speed (1/2000s vs 1/500s) to freeze action.
- Faster burst: Shoots at higher frequency (10 vs 5 flaps/sec) to capture the decisive moment.
- Ready to shoot: Has an integrated lens, whereas the GM1 necessitates an extra lens.
- Longer lasting: Gets more shots (370 versus 230) 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.
- Easier wireless transfer: Supports Bluetooth for image sharing without cables.
- More modern: Reflects 4 years and 3 months of technical progress since the GM1 launch.
If the number of relative strengths (bullet points above) is taken as a guide, the TZ200 is the clear winner of the contest (11 : 3 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 GM1 and the Panasonic TZ200 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the GM1 or the TZ200 perform in practice. 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 summary-table relays the overall verdicts of several of the most popular 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 are only valid when referring to cameras in the same category and of the same age. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
