Canon 40D vs Panasonic GH1
The Canon EOS 40D and the Panasonic Lumix DMC-GH1 are two enthusiast cameras that were announced, respectively, in August 2007 and March 2009. The 40D is a DSLR, while the GH1 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (40D) and a Four Thirds (GH1) sensor. The Canon has a resolution of 10.1 megapixels, whereas the Panasonic provides 12 MP. Read on to find out how these two cameras compare with respect to their body size, their sensors, their features, their input-output connections, and their reception by expert reviewers.

Body comparison: Canon 40D vs Panasonic GH1
The physical size and weight of the Canon 40D and the Panasonic GH1 are illustrated in the side-by-side display below. 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic GH1 is notably smaller (29 percent) than the Canon 40D. Moreover, the GH1 is substantially lighter (53 percent) than the 40D. In this context, it is worth noting that neither the 40D nor the GH1 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 (GH1). Mirrorless cameras, such as the GH1, 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 adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, just use the right or left arrows in the table to switch to the respective camera. Alternatively, you can also navigate to the CAM-parator app and make your selection from the full list of cameras there.

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 40D was launched at a somewhat lower price (by 13 percent) than the GH1, which makes it more attractive for photographers on a tight budget. 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.
Sensor comparison: Canon 40D vs Panasonic GH1
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon 40D features an APS-C sensor and the Panasonic GH1 a Four Thirds sensor. The sensor area in the GH1 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 GH1 offers a 4:3 aspect.
Despite having a smaller sensor, the GH1 offers a higher resolution of 12 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 4.33μm versus 5.73μm for the 40D). However, it should be noted that the GH1 is a somewhat more recent model (by 1 year and 6 months) than the 40D, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.
The Canon EOS 40D has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200.. The Panasonic Lumix DMC-GH1 offers exactly the same ISO settings.
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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. 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 also of capturing video footage. The GH1 indeed provides for movie recording, while the 40D does not. The highest resolution format that the GH1 can use is 1080/24p.
Feature comparison: Canon 40D vs Panasonic GH1
Beyond body and sensor, cameras can and do differ across a range of features. For example, the GH1 has an electronic viewfinder (1440k dots), while the 40D 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 table below summarizes some of the other core capabilities of the Canon 40D and Panasonic GH1 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 40D, but is missing on the GH1 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 GH1 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 40D writes its imaging data to Compact Flash cards, while the GH1 uses SDHC cards.

Studio photographers will appreciate that the Canon 40D (unlike the GH1) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 40D and the GH1 have been discontinued, but can regularly be found used on eBay. The 40D was replaced by the Canon 50D, while the GH1 was followed by the Panasonic GH2.
Review summary: Canon 40D vs Panasonic GH1
So what conclusions can be drawn? Is the Canon 40D better than the Panasonic GH1 or vice versa? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Canon EOS 40D:
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- Easier setting verification: Features an LCD display on top to control shooting parameters.
- Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
- Faster burst: Shoots at higher frequency (6.5 vs 3 flaps/sec) to capture the decisive moment.
- Longer lasting: Can take more shots (750 versus 300) on a single battery charge.
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- More affordable: Was introduced into a lower priced segment (13 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in August 2007).
Advantages of the Panasonic Lumix DMC-GH1:
- More detail: Has more megapixels (12 vs 10.1MP), which boosts linear resolution by 7%.
- Broader imaging potential: Can capture not only stills but also 1080/24p video.
- More framing info: Has an electronic viewfinder that displays shooting data.

- More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- More compact: Is smaller (124x90mm vs 146x108mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 437g or 53 percent) and is thus easier to take along.
- More legacy lens friendly: Can use many non-native lenses via adapters.
- More modern: Was introduced somewhat (1 year and 6 months) more recently.
If the count of individual advantages (bullet points above) is taken as a guide, the GH1 emerges as the winner of the match-up (10 : 8 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.
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 handling experience and imaging performance when actually working with the 40D or the GH1. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
