Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-G1 and the Pentax K-1? 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: Panasonic G1 vs Pentax K-1
The side-by-side display below illustrates the physical size and weight of the Panasonic G1 and the Pentax K-1. 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 K-1 can be obtained in two different colors (black, silver), while the G1 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 Pentax K-1 is considerably larger (45 percent) than the Panasonic G1. Moreover, the K-1 is substantially heavier (181 percent) than the G1. It is noteworthy in this context that the K-1 is splash and dust-proof, while the G1 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.

|Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.|
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 G1 was launched at a markedly lower price (by 67 percent) than the K-1, 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.
Sensor comparison: Panasonic G1 vs Pentax K-1
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 G1 features a Four Thirds sensor and the Pentax K-1 a full frame sensor. The sensor area in the K-1 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 G1 has a native 4:3 aspect ratio, while the one in the K-1 offers a 3:2 aspect.
In terms of underlying technology, both cameras are build around CMOS sensors.
With 36.2MP, the K-1 offers a higher resolution than the G1 (12MP), but the K-1 nevertheless has larger individual pixels (pixel pitch of 4.88μm versus 4.33μm for the G1) due to its larger sensor. Moreover, the K-1 is a much more recent model (by 7 years and 5 months) than the G1, 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 K-1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Pentax K-1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the K-1 for good quality output (200 dots per inch) amounts to 36.8 x 24.6 inch or 93.5 x 62.4 cm, for very good quality (250 dpi) 29.4 x 19.6 inch or 74.8 x 49.9 cm, and for excellent quality (300 dpi) 24.5 x 16.4 inch or 62.3 x 41.6 cm. The corresponding values for the Panasonic G1 are 20 x 15 inch or 50.8 x 38.1 cm for good quality, 16 x 12 inch or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inch or 33.9 x 25.4 cm for excellent quality prints.
Unlike the G1, the K-1 has the capacity to capture high quality composite images by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).
The Panasonic Lumix DMC-G1 has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Pentax K-1 are ISO 100 to ISO 204800 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. 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 K-1 offers substantially better image quality than the G1 (overall score 43 points higher). The advantage is based on 4.3 bits higher color depth, 4.3 EV in additional dynamic range, and 2.8 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. The K-1 indeed provides for movie recording, while the G1 does not. The highest resolution format that the K-1 can use is 1080/60i.
Feature comparison: Panasonic G1 vs Pentax K-1
Apart from body and sensor, cameras can and do differ across a range of features. For example, the G1 has an electronic viewfinder (1440k dots), while the K-1 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinders of both cameras offer the same field of view (100%), as well as the same magnification (0.70x). The adjacent table lists some of the other core features of the Panasonic G1 and Pentax K-1 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The G1 has one, while the K-1 does not. While the built-in flash of the G1 is not very powerful, it can at times be useful as a fill-in light.The G1 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 K-1 does not have a selfie-screen.
The Pentax K-1 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 G1 writes its imaging data to SDHC cards, while the K-1 uses SDXC cards. The K-1 features dual card slots, which can be very useful in case a memory card fails. In contrast, the G1 only has one slot. The K-1 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the G1 cannot take advantage of Ultra High Speed SD cards.
Connectivity comparison: Panasonic G1 vs Pentax K-1
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-G1 and Pentax K-1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the K-1 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the G1 does not offer wifi capability.
Studio photographers will appreciate that the Pentax K-1 (unlike the G1) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the G1 and the K-1 have been discontinued, but can regularly be found used on eBay. The G1 was replaced by the Panasonic G2, while the K-1 was followed by the Pentax K-1 II. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Panasonic and Pentax websites.

If the count of relative strengths (bullet points above) is taken as a measure, the K-1 is the clear winner of the contest (23 : 9 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 G1 and the Pentax K-1 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 technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the G1 and the K-1 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.
Expert reviews: Panasonic G1 vs Pentax K-1
This is where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

|Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (-) not available.|
The review scores listed above should be treated 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
