Canon 20D vs Panasonic G1
The Canon EOS 20D and the Panasonic Lumix DMC-G1 are two digital cameras that were officially introduced, respectively, in August 2004 and September 2008. The 20D is a DSLR, while the G1 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (20D) and a Four Thirds (G1) sensor. The Canon has a resolution of 8.2 megapixels, whereas the Panasonic provides 12 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 20D and the Panasonic Lumix DMC-G1? 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
An illustration of the physical size and weight of the Canon 20D and the Panasonic G1 is provided 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 dimensions 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 G1 is considerably smaller (32 percent) than the Canon 20D. Moreover, the G1 is substantially lighter (53 percent) than the 20D. In this context, it is worth noting that neither the 20D nor the G1 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 (20D) and the Micro Four Thirds Lens Catalog (G1). Mirrorless cameras, such as the G1, 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.
Concerning battery life, the 20D gets 700 shots out of its Canon BP-511A battery, while the G1 can take 410 images on a single charge of its Panasonic DMW-BLB13 power pack.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

Any camera decision will obviously take relative prices into account. 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 G1 was launched at a markedly lower price (by 60 percent) than the 20D, 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
The size of the sensor inside a digital camera is one of the key determinants 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. 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon 20D features an APS-C sensor and the Panasonic G1 a Four Thirds sensor. The sensor area in the G1 is 33 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 20D has a native 3:2 aspect ratio, while the one in the G1 offers a 4:3 aspect.
Despite having a smaller sensor, the G1 offers a higher resolution of 12 megapixels, compared with 8.2 MP of the 20D. 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 6.42μm for the 20D). However, it should be noted that the G1 is much more recent (by 4 years) than the 20D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The resolution advantage of the Panasonic G1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G1 for good quality output (200 dots per inch) amounts to 20 x 15 inches or 50.8 x 38.1 cm, for very good quality (250 dpi) 16 x 12 inches or 40.6 x 30.5 cm, and for excellent quality (300 dpi) 13.3 x 10 inches or 33.9 x 25.4 cm. The corresponding values for the Canon 20D are 17.5 x 11.7 inches or 44.5 x 29.7 cm for good quality, 14 x 9.3 inches or 35.6 x 23.7 cm for very good quality, and 11.7 x 7.8 inches or 29.7 x 19.8 cm for excellent quality prints.
The Canon EOS 20D has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The Panasonic Lumix DMC-G1 offers exactly the same ISO settings.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under review, the 20D has a notably higher overall DXO score than the G1 (overall score 9 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.8 bits higher color depth, 0.7 EV in additional dynamic range, and 0.6 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Feature comparison
Beyond 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 20D 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 viewfinder in the G1 offers a wider field of view (100%) than the one in the 20D (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the G1 has a higher magnification (0.70x vs 0.56x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Canon 20D and Panasonic G1 along with similar information for a selection of comparators.

One feature that is present on the 20D, but is missing on the G1 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 G1 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 20D does not have a selfie-screen.The 20D writes its imaging data to Compact Flash cards, while the G1 uses SDHC cards.
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 Canon EOS 20D and Panasonic Lumix DMC-G1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon 20D (unlike the G1) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 20D and the G1 have been discontinued, but can regularly be found used on ebay. The 20D was replaced by the Canon 30D, while the G1 was followed by the Panasonic G2. Further information on the features and operation of the 20D and G1 can be found, respectively, in the Canon 20D Manual (free pdf) or the online Panasonic G1 Manual.
Review summary
So what conclusions can be drawn? Is the Canon 20D better than the Panasonic G1 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Canon EOS 20D:
- Better image quality: Scores markedly higher (9 points) in the DXO overall assessment.
- More dynamic range: Captures a larger spectrum of light and dark details (0.7 EV of extra DR).
- Better low-light sensitivity: Requires less light for good images (0.6 stops ISO advantage).
- 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 (1/8000s vs 1/4000s) to freeze action.
- Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
- Longer lasting: Can take more shots (700 versus 410) on a single battery charge.
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- More heavily discounted: Has been available for much longer (launched in August 2004).
Advantages of the Panasonic Lumix DMC-G1:
- More detail: Has more megapixels (12 vs 8.2MP), which boosts linear resolution by 19%.
- More framing info: Has an electronic viewfinder that displays shooting data.
- More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.56x).
- Larger screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (460k vs 118k dots).
- More flexible LCD: Has a 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 (124x84mm vs 144x106mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 410g or 53 percent) and is thus easier to take along.
- More legacy lens friendly: Can use many non-native lenses via adapters.
- Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
- More affordable: Was introduced into a lower priced category (60 percent cheaper at launch).
- More modern: Reflects 4 years of technical progress since the 20D launch.
If the count of relative strengths (bullet points above) is taken as a measure, the G1 is the clear winner of the contest (14 : 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 Canon 20D and the Panasonic G1 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 20D or the G1. 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.
Expert reviews
This is why expert reviews 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
