Panasonic GM1 vs Sony A99 II
The Panasonic Lumix DMC-GM1 and the Sony Alpha ALT-A99 II are two digital cameras that were officially introduced, respectively, in October 2013 and September 2016. The GM1 is a mirrorless interchangeable lens camera, while the A99 II is a DSLR. The cameras are based on a Four Thirds (GM1) and a full frame (A99 II) sensor. The Panasonic has a resolution of 15.8 megapixels, whereas the Sony provides 42.2 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 Sony Alpha ALT-A99 II? 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.
Body comparison
The physical size and weight of the Panasonic GM1 and the Sony A99 II 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 measures are rounded to the nearest millimeter.
The GM1 can be obtained in three different colors (black, silver, red), while the A99 II 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 Sony A99 II is considerably larger (173 percent) than the Panasonic GM1. Moreover, the A99 II is substantially heavier (316 percent) than the GM1. It is noteworthy in this context that the A99 II is splash and dust-proof, while the GM1 does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.
Concerning battery life, the GM1 gets 230 shots out of its DMW-BLH7 battery, while the A99 II can take 490 images on a single charge of its NP-FM500H power pack.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

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 GM1 was launched at a markedly lower price (by 77 percent) than the A99 II, which puts it into a different market segment. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
Sensor comparison
The size of the imaging sensor is a crucial determinant 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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Panasonic GM1 features a Four Thirds sensor and the Sony A99 II a full frame sensor. The sensor area in the A99 II is 283 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.0. The sensor in the GM1 has a native 4:3 aspect ratio, while the one in the A99 II offers a 3:2 aspect.
With 42.2MP, the A99 II offers a higher resolution than the GM1 (15.8MP), but the A99 II nevertheless has larger individual pixels (pixel pitch of 4.52μm versus 3.77μm for the GM1) due to its larger sensor. Moreover, the A99 II is a much more recent model (by 2 years and 11 months) than the GM1, 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 A99 II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Sony A99 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A99 II for good quality output (200 dots per inch) amounts to 39.8 x 26.5 inches or 101 x 67.4 cm, for very good quality (250 dpi) 31.8 x 21.2 inches or 80.8 x 53.9 cm, and for excellent quality (300 dpi) 26.5 x 17.7 inches or 67.3 x 44.9 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 A99 II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
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 Sony Alpha ALT-A99 II are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-25600.
In terms of underlying technology, the GM1 is build around a CMOS sensor, while the A99 II uses a BSI-CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.
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"). Of the two cameras under consideration, the A99 II offers substantially better image quality than the GM1 (overall score 26 points higher). The advantage is based on 3.1 bits higher color depth, 1.7 EV in additional dynamic range, and 1.8 stops in additional low light sensitivity. 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 cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the A99 II provides a better video resolution than the GM1. It can shoot movie footage at 4K/30p, while the Panasonic is limited to 1080/60i.
Feature comparison
Beyond body and sensor, cameras can and do differ across a range of features. For example, the A99 II has an electronic viewfinder (2400k 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 following table reports on some other key feature differences and similarities of the Panasonic GM1, the Sony A99 II, and comparable cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one. |
One difference between the cameras concerns the presence of an on-board flash. The GM1 has one, while the A99 II does not. While the built-in flash of the GM1 is not very powerful, it can at times be useful as a fill-in light.
The A99 II has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the GM1 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 GM1 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 GM1 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.
The GM1 writes its imaging data to SDXC cards, while the A99 II uses SDXC or Memory Stick PRO Duo cards. The A99 II features dual card slots, which can be very useful in case a memory card fails. In contrast, the GM1 only has one slot. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
Connectivity comparison
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 Sony Alpha ALT-A99 II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A99 II has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The GM1 lacks such a headphone port.
Studio photographers will appreciate that the Sony A99 II (unlike the GM1) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the GM1 and the A99 II have been discontinued, but can regularly be found used on ebay. The GM1 was replaced by the Panasonic GM5, while the A99 II does not have a direct successor. Further information on the features and operation of the GM1 and A99 II can be found, respectively, in the Panasonic GM1 Manual (free pdf) or the online Sony A99 II Manual.

If the count of individual advantages (bullet points above) is taken as a guide, the A99 II is the clear winner of the contest (26 : 10 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 GM1 and the Sony A99 II place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR 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 says little about, for example, the shooting experience and imaging performance of the GM1 and the A99 II in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
Expert reviews
This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], 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.

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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
