Canon 40D vs Panasonic GX800
The Canon EOS 40D and the Panasonic Lumix DMC-GX800 (labelled Panasonic GX850 in some countries) are two digital cameras that were officially introduced, respectively, in August 2007 and January 2017. The 40D is a DSLR, while the GX800 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (40D) and a Four Thirds (GX800) sensor. The Canon has a resolution of 10.1 megapixels, whereas the Panasonic 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 Canon EOS 40D and the Panasonic Lumix DMC-GX800? 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: Canon 40D vs Panasonic GX800
The physical size and weight of the Canon 40D and the Panasonic GX800 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.
The GX800 can be obtained in three different colors (black, silver, red), while the 40D 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 GX800 is considerably smaller (56 percent) than the Canon 40D. Moreover, the GX800 is substantially lighter (67 percent) than the 40D. In this context, it is worth noting that neither the 40D nor the GX800 are weather-sealed.
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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (40D) and the Micro Four Thirds Lens Catalog (GX800). Mirrorless cameras, such as the GX800, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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. The GX800 was launched at a markedly lower price (by 58 percent) than the 40D, 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: Canon 40D vs Panasonic GX800
The size of the sensor inside a digital camera is one of the key determinants 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon 40D features an APS-C sensor and the Panasonic GX800 a Four Thirds sensor. The sensor area in the GX800 is 32 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 2.0. The sensor in the 40D has a native 3:2 aspect ratio, while the one in the GX800 offers a 4:3 aspect.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
Despite having a smaller sensor, the GX800 offers a higher resolution of 15.8 megapixels, compared with 10.1 MP of the 40D. 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 3.77μm versus 5.73μm for the 40D). However, it should be noted that the GX800 is much more recent (by 9 years and 4 months) than the 40D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. 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 GX800 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GX800 for good quality output (200 dots per inch) amounts to 23 x 17.2 inch or 58.3 x 43.8 cm, for very good quality (250 dpi) 18.4 x 13.8 inch or 46.7 x 35 cm, and for excellent quality (300 dpi) 15.3 x 11.5 inch or 38.9 x 29.2 cm. The corresponding values for the Canon 40D are 19.4 x 13 inch or 49.4 x 32.9 cm for good quality, 15.6 x 10.4 inch or 39.5 x 26.3 cm for very good quality, and 13 x 8.6 inch or 32.9 x 21.9 cm for excellent quality prints.
The Canon EOS 40D 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 Panasonic Lumix DMC-GX800 are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
For many cameras, data on sensor performance has been reported by DXO Mark. 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. Of the two cameras under consideration, the GX800 has a markedly higher DXO score than the 40D (overall score 9 points higher), which will translate into better image quality. The advantage is based on 1.1 bits higher color depth, 2 EV in additional dynamic range, and 0.3 stops of reduced 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 are not only capable of taking still images, but also of capturing video footage. The GX800 indeed provides for movie recording, while the 40D does not. The highest resolution format that the GX800 can use is 4K/30p.
Feature comparison: Canon 40D vs Panasonic GX800
Beyond body and sensor, cameras can and do differ across a range of features. For example, the 40D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the GX800 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon 40D and Panasonic GX800 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 40D, but is missing on the GX800 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.The GX800 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 40D 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 GX800 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 GX800 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 40D writes its imaging data to Compact Flash cards, while the GX800 uses SDXC cards.
Connectivity comparison: Canon 40D vs Panasonic GX800
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 Canon EOS 40D and Panasonic Lumix DMC-GX800 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 40D has a hotshoe, while the GX800 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.
Studio photographers will appreciate that the Canon 40D (unlike the GX800) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The GX800 is a recent model that features in the current product line-up of Panasonic. In contrast, the 40D has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 40D was succeeded by the Canon 50D. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Panasonic websites.
Review summary: Canon 40D vs Panasonic GX800
So what is the bottom line? Is there a clear favorite between the Canon 40D and the Panasonic GX800? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

If the count of relative strengths (bullet points above) is taken as a measure, the GX800 is the clear winner of the contest (19 : 8 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 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 Canon 40D and the Panasonic GX800 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 40D or the GX800. 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: Canon 40D vs Panasonic GX800
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 review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
