Canon 250D vs Leica M Typ 240

The Canon EOS 250D (called Canon SL3 in some regions) and the Leica M (Typ 240) are two digital cameras that were announced, respectively, in April 2019 and September 2012. The 250D is a DSLR, while the M Typ 240 is a rangefinder-focusing mirrorless camera. The cameras are based on an APS-C (250D) and a full frame (M Typ 240) sensor. The Canon has a resolution of 24 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 250D 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.

Body comparison

An illustration of the physical size and weight of the Canon 250D and the Leica M Typ 240 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.

The 250D can be obtained in two different colors (black, white), while the M Typ 240 is also available in two color-versions, but different ones (black, silver).

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 somewhat smaller (2 percent) than the Canon 250D. However, the M Typ 240 is substantially heavier (51 percent) than the 250D. It is noteworthy in this context that the M Typ 240 is splash and dust-proof, while the 250D 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 (250D) and the Leica M Lens Catalog (M Typ 240).

Concerning battery life, the 250D gets 1070 shots out of its Canon LP-E17 battery, while the M Typ 240 can take 500 images on a single charge of its Leica BP-SCL2 power pack.

Any camera decision will naturally be influenced heavily by the price. 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 250D was launched at a markedly lower price (by 91 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 250D features an APS-C sensor and the Leica M Typ 240 a full frame sensor. The sensor area in the M Typ 240 is 158 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.

Despite having a smaller sensor, the Canon 250D offers a higher resolution of 24 megapixels, compared with 23.7 MP of the Leica M Typ 240. 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 3.72μm versus 6.01μm for the M Typ 240). However, it should be noted that the 250D is much more recent (by 6 years and 6 months) than the M Typ 240, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The 250D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS 250D has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 100-51200. 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.

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 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"). The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Note: DXO values in italics represent estimates based on sensor size and age.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the 250D provides a higher video resolution than the M Typ 240. It can shoot video footage at 4K/25p, while the Leica is limited to 1080/25p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The 250D 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 250D (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 0.54x), 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 250D and Leica M Typ 240 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The 250D has one, while the M Typ 240 does not. While the built-in flash of the 250D is not very powerful, it can at times be useful as a fill-in light.

The Canon 250D 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.

Concerning the storage of imaging data, both the 250D and the M Typ 240 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

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 250D and Leica M (Typ 240) and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 250D has a microphone port, which is missing on the M Typ 240. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

The 250D is a recent model that features in the current product line-up of Canon. In contrast, the M Typ 240 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the M Typ 240 was succeeded by the Leica M Typ 262. Further information on the features and operation of the 250D and M Typ 240 can be found, respectively, in the Canon 250D Manual (free pdf) or the online Leica M Typ 240 Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Canon 250D and the Leica M Typ 240? Which camera is better? The listing below highlights the relative strengths of the two models.

Arguments in favor of the Canon EOS 250D:

• Better video: Provides higher definition movie capture (4K/25p vs 1080/25p).
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• Better sound: Can connect to an external microphone for higher quality sound recording.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 920k dots).
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Less heavy: Is lighter (by 231g or 34 percent) and hence easier to carry around.
• Longer lasting: Can take more shots (1070 versus 500) on a single battery charge.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More affordable: Was introduced into a lower priced category (91 percent cheaper at launch).
• More modern: Reflects 6 years and 6 months of technical progress since the M Typ 240 launch.

Advantages of the Leica M (Typ 240):

• 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 (0.68x vs 0.54x).
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
• More heavily discounted: Has been around for much longer (launched in September 2012).

If the count of relative strengths (bullet points above) is taken as a measure, the 250D is the clear winner of the match-up (16 : 5 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the 250D or the M Typ 240 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

The above review scores should be interpreted with care, 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.
