Canon 20D vs Leica M Typ 240
The Canon EOS 20D and the Leica M (Typ 240) are two enthusiast cameras that were announced, respectively, in August 2004 and September 2012. The 20D is a DSLR, while the M Typ 240 is a rangefinder-style mirrorless camera. The cameras are based on an APS-C (20D) and a full frame (M Typ 240) sensor. The Canon has a resolution of 8.2 megapixels, whereas the Leica provides 23.7 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 Leica M (Typ 240)? 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.
The physical size and weight of the Canon 20D and the Leica M Typ 240 are illustrated in the side-by-side display below. 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 size dimensions are rounded to the nearest millimeter.
The M Typ 240 can be obtained in two different colors (black, silver), 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 Leica M Typ 240 is notably smaller (27 percent) than the Canon 20D. Moreover, the M Typ 240 is markedly lighter (12 percent) than the 20D. It is noteworthy in this context that the M Typ 240 is splash and dust-proof, while the 20D 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. 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 Leica M Lens Catalog (M Typ 240).
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 20D was launched at a markedly lower price (by 78 percent) than the M Typ 240, which puts it into a different market segment. 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.
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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon 20D features an APS-C sensor and the Leica M Typ 240 a full frame sensor. The sensor area in the M Typ 240 is 153 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
With 23.7MP, the M Typ 240 offers a higher resolution than the 20D (8.2MP), but the M Typ 240 has smaller individual pixels (pixel pitch of 6.01μm versus 6.42μm for the 20D). Yet, the M Typ 240 is a much more recent model (by 8 years and 1 month) than the 20D, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Leica M Typ 240 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M Typ 240 for good quality output (200 dots per inch) amounts to 29.8 x 19.9 inches or 75.6 x 50.5 cm, for very good quality (250 dpi) 23.8 x 15.9 inches or 60.5 x 40.4 cm, and for excellent quality (300 dpi) 19.8 x 13.3 inches or 50.4 x 33.7 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 Leica M (Typ 240) are ISO 200 to ISO 6400, with the possibility to increase the ISO range to 100-6400.
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. Of the two cameras under consideration, the M Typ 240 offers substantially better image quality than the 20D (overall score 22 points higher). The advantage is based on 2.1 bits higher color depth, 2.3 EV in additional dynamic range, and 1.4 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 M Typ 240 indeed provides for movie recording, while the 20D does not. The highest resolution format that the M Typ 240 can use is 1080/25p.
Beyond body and sensor, cameras can and do differ across a range of features. The 20D and the M Typ 240 are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The viewfinder in the M Typ 240 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 M Typ 240 has a higher magnification (0.68x 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 Leica M Typ 240 along with similar information for a selection of comparators.

|Leica M Typ 262||optical||n||3.0||921||fixed||n||1/4000s||3.0||n||n|
One difference between the cameras concerns the presence of an on-board flash. The 20D has one, while the M Typ 240 does not. While the built-in flash of the 20D is not very powerful, it can at times be useful as a fill-in light.
The 20D writes its imaging data to Compact Flash cards, while the M Typ 240 uses SDXC cards.
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 Leica M (Typ 240) 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 M Typ 240) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 20D and the M Typ 240 have been discontinued, but can regularly be found used on eBay. The 20D was replaced by the Canon 30D, while the M Typ 240 was followed by the Leica M Typ 262. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Leica websites.
So what is the bottom line? Is the Canon 20D better than the Leica M Typ 240 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Canon EOS 20D:
- 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.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- More affordable: Was introduced into a lower priced category (78 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in August 2004).
Arguments in favor of the Leica M (Typ 240):
- More detail: Has more megapixels (23.7 vs 8.2MP), which boosts linear resolution by 70%.
- Better image quality: Scores substantially higher (22 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (2.1 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (2.3 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (1.4 stops ISO advantage).

If the count of individual advantages (bullet points above) is taken as a guide, the M Typ 240 is the clear winner of the contest (16 : 7 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. 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.
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 20D and the M Typ 240 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.
This is why hands-on reviews by experts are important. 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 above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
