Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 20D and the Panasonic Lumix DMC-LX5? 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 Canon 20D and the Panasonic LX5 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 LX5 can be obtained in two different colors (black, white), while the 20D 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 LX5 is considerably smaller (53 percent) than the Canon 20D. In this context, it is worth noting that neither the 20D nor the LX5 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the LX5 has a lens built in, whereas the 20D is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the 20D and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the 20D gets 700 shots out of its Canon BP-511A battery, while the LX5 can take 400 images on a single charge of its Panasonic DMW-BCJ13 power pack.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The LX5 was launched at a lower price than the 20D, despite having a lens built in. 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 generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 20D features an APS-C sensor and the Panasonic LX5 a 1/1.7-inch sensor. The sensor area in the LX5 is 86 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 4.4. The sensor in the 20D has a native 3:2 aspect ratio, while the one in the LX5 offers a 4:3 aspect. The LX5 has the particularity of featuring a switch that allows to toggle between multiple aspect ratios, while maintaining the same field of view and full image resolution.

Despite having a smaller sensor, the LX5 offers a higher resolution of 10 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 2.14μm versus 6.42μm for the 20D). However, it should be noted that the LX5 is much more recent (by 5 years and 11 months) 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 LX5 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the LX5 for good quality output (200 dots per inch) amounts to 18.2 x 13.7 inches or 46.3 x 34.7 cm, for very good quality (250 dpi) 14.6 x 10.9 inches or 37.1 x 27.8 cm, and for excellent quality (300 dpi) 12.2 x 9.1 inches or 30.9 x 23.2 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 corresponding ISO settings for the Panasonic Lumix DMC-LX5 are ISO 80 to ISO 3200, with the possibility to increase the ISO range to 80-12800.

In terms of underlying technology, the 20D is build around a CMOS sensor, while the LX5 uses a CCD 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.

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 review, the 20D provides substantially higher image quality than the LX5, with an overall score that is 21 points higher. This advantage is based on 2.3 bits higher color depth, 0.2 EV in additional dynamic range, and 2.4 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.

Many modern cameras are not only capable of taking still images, but can also record movies. The LX5 indeed provides for movie recording, while the 20D does not. The highest resolution format that the LX5 can use is 720/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the 20D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the LX5 relies on live view and the rear LCD for framing. That said, the LX5 can be equipped with an optional viewfinder – the DMW-LVF1. The table below summarizes some of the other core capabilities of the Canon 20D and Panasonic LX5 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 20D, but is missing on the LX5 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 20D writes its imaging data to Compact Flash cards, while the LX5 uses SDXC 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-LX5 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 LX5) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 20D and the LX5 have been discontinued, but can regularly be found used on ebay. The 20D was replaced by the Canon 30D, while the LX5 was followed by the Panasonic LX7. Further information on the features and operation of the 20D and LX5 can be found, respectively, in the Canon 20D Manual (free pdf) or the online Panasonic LX5 Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Canon 20D or the Panasonic LX5 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Canon EOS 20D:

• Better image quality: Scores substantially higher (21 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (2.3 bits more color depth).
• Better low-light sensitivity: Requires less light for good images (2.4 stops ISO advantage).
• Easier framing: Has an optical viewfinder for image composition and settings control.
• 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 2.5 flaps/sec) to capture the decisive moment.
• More flexible: Can take a variety of interchangeable lenses, including specialty optics.
• Longer lasting: Can take more shots (700 versus 400) 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).

Reasons to prefer the Panasonic Lumix DMC-LX5:

• More detail: Has more megapixels (10 vs 8.2MP), which boosts linear resolution by 8%.
• Flexible image proportions: Has a multi-aspect sensor that allows for alternative image shapes.
• Broader imaging potential: Can capture not only stills but also 720/60p video.
• 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).
• Ready to shoot: Comes with an integrated lens, while the 20D requires a separate lens.
• More compact: Is smaller (110x65mm vs 144x106mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the 20D).
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 5 years and 11 months of technical progress since the 20D launch.

If the number of relative strengths (bullet points above) is taken as a guide, the LX5 comes out slightly ahead of the 20D (12 : 11 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 20D and the Panasonic LX5 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Travel-Zoom 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 20D and the LX5 in practical situations. 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 adjacent summary-table relays the overall verdicts of several of the most popular 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

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 comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
