Panasonic FZ100 vs GM5
The Panasonic Lumix DMC-FZ100 and the Panasonic Lumix DMC-GM5 are two digital cameras that were revealed to the public, respectively, in July 2010 and September 2014. The FZ100 is a fixed lens compact, while the GM5 is a mirrorless interchangeable lens camera. The cameras are based on a 1/2.3-inch (FZ100) and a Four Thirds (GM5) sensor. The FZ100 has a resolution of 14 megapixels, whereas the GM5 provides 15.8 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-FZ100 and the Panasonic Lumix DMC-GM5? 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 side-by-side display below illustrates the physical size and weight of the Panasonic FZ100 and the Panasonic GM5. The two cameras are presented according to their relative size. 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.
The GM5 can be obtained in two different colors (black, silver), while the FZ100 is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GM5 is considerably smaller (42 percent) than the Panasonic FZ100. In this context, it is worth noting that neither the FZ100 nor the GM5 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the FZ100 has a lens built in, whereas the GM5 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 GM5 and their specifications in the Micro Four Thirds Lens Catalog.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The FZ100 was launched at a lower price than the GM5, despite having a lens built in. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 sensor inside a digital camera is one of the key determinants 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Panasonic FZ100 features a 1/2.3-inch sensor and the Panasonic GM5 a Four Thirds sensor. The sensor area in the GM5 is 704 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 2.0. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.
With 15.8MP, the GM5 offers a higher resolution than the FZ100 (14MP), but the GM5 nevertheless has larger individual pixels (pixel pitch of 3.77μm versus 1.41μm for the FZ100) due to its larger sensor. Moreover, the GM5 is a much more recent model (by 4 years and 1 month) than the FZ100, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the FZ100 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Panasonic GM5 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GM5 for good quality output (200 dots per inch) amounts to 23 x 17.2 inches or 58.3 x 43.8 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.7 x 35 cm, and for excellent quality (300 dpi) 15.3 x 11.5 inches or 38.9 x 29.2 cm. The corresponding values for the Panasonic FZ100 are 21.6 x 16.2 inches or 54.9 x 41.1 cm for good quality, 17.3 x 13 inches or 43.9 x 32.9 cm for very good quality, and 14.4 x 10.8 inches or 36.6 x 27.4 cm for excellent quality prints.
The Panasonic Lumix DMC-FZ100 has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-6400. The corresponding ISO settings for the Panasonic Lumix DMC-GM5 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. 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 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 GM5 provides a faster frame rate than the FZ100. It can shoot movie footage at 1080/60p, while the FZ100 is limited to 1080/60i.
Apart from body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the GM5 offers a substantially higher resolution than the one in the FZ100 (1166k vs 202k dots). The table below summarizes some of the other core capabilities of the Panasonic FZ100 and Panasonic GM5 in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The FZ100 has one, while the GM5 does not. While the built-in flash of the FZ100 is not very powerful, it can at times be useful as a fill-in light.The FZ100 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the GM5 does not have a selfie-screen.
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, the GM5 is one of those camera that have an additional 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 GM5 has 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 FZ100 and the GM5 write their files to SDXC cards. The GM5 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the FZ100 cannot take advantage of Ultra High Speed SD cards.
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-FZ100 and Panasonic Lumix DMC-GM5 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

|10.||Leica V-LUX 2||Y||stereo||mono||-||-||mini||2.0||-||-||-|
It is notable that the GM5 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the FZ100 does not provide wifi capability.
Both the FZ100 and the GM5 have been discontinued, but can regularly be found used on eBay. The FZ100 was replaced by the Panasonic FZ150, while the GM5 does not have a direct successor. 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 FZ100 better than the Panasonic GM5 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

If the count of individual advantages (bullet points above) is taken as a guide, the GM5 is the clear winner of the contest (17 : 11 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 before making a camera decision. 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 FZ100 and the Panasonic GM5 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best Mirrorless Interchangeable Lens 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the FZ100 or the GM5. 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 hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). 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 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 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.
