Canon 4000D vs Leica M9

The Canon EOS 4000D (called Canon T100 in some regions) and the Leica M9 are two digital cameras that were announced, respectively, in February 2018 and September 2009. The 4000D is a DSLR, while the M9 is a rangefinder-focusing mirrorless camera. The cameras are based on an APS-C (4000D) and a full frame (M9) sensor. The Canon has a resolution of 17.9 megapixels, whereas the Leica provides 18.1 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 4000D and the Leica M9? 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 4000D and the Leica M9 is provided 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 width, height and depth measures are rounded to the nearest millimeter.

The M9 can be obtained in two different colors (black, silver), while the 4000D 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 M9 is notably smaller (15 percent) than the Canon 4000D. However, the M9 is markedly heavier (34 percent) than the 4000D. In this context, it is worth noting that neither the 4000D nor the M9 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 (4000D) and the Leica M Lens Catalog (M9).

Concerning battery life, the 4000D gets 500 shots out of its Canon LP-E10 battery, while the M9 can take 550 images on a single charge of its Leica BLI-312 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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 4000D was launched at a markedly lower price (by 95 percent) than the M9, 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. 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 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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 4000D features an APS-C sensor and the Leica M9 a full frame sensor. The sensor area in the M9 is 160 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.

With 18.1MP, the M9 offers a higher resolution than the 4000D (17.9MP), but the M9 nevertheless has larger individual pixels (pixel pitch of 6.91μm versus 4.31μm for the 4000D) due to its larger sensor. However, the 4000D is a much more recent model (by 8 years and 5 months) than the M9, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the M9 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The Canon EOS 4000D has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-12800. The corresponding ISO settings for the Leica M9 are ISO 80 to ISO 2500 (no boost).

In terms of underlying technology, the 4000D is build around a CMOS sensor, while the M9 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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 M9 has a markedly higher DXO score than the 4000D (overall score 6 points higher), which will translate into better image quality. The advantage is based on 0.6 bits higher color depth, 0.3 EV in additional dynamic range, and 0.3 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 are not only capable of taking still images, but can also record movies. The 4000D indeed provides movie recording capabilities, while the M9 does not. The highest resolution format that the 4000D can use is 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The 4000D and the M9 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 M9 offers a wider field of view (100%) than the one in the 4000D (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the M9 has a higher magnification (0.68x vs 0.50x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Canon 4000D and Leica M9 in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The 4000D has one, while the M9 does not. While the built-in flash of the 4000D is not very powerful, it can at times be useful as a fill-in light.

Concerning the storage of imaging data, both the 4000D and the M9 write their files to 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 4000D and Leica M9 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 4000D offers wifi support, while the M9 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

The 4000D is a recent model that features in the current product line-up of Canon. In contrast, the M9 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the M9 was succeeded by the Leica M Typ 240. Further information on the features and operation of the 4000D and M9 can be found, respectively, in the Canon 4000D Manual (free pdf) or the online Leica M9 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Canon 4000D and the Leica M9? Which camera is better? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Canon EOS 4000D:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Broader imaging potential: Can record not only still images but also 1080/30p movies.
• Larger screen: Has a bigger rear LCD (2.7" vs 2.5") for image review and settings control.
• Faster burst: Shoots at higher frequency (3 vs 2 flaps/sec) to capture the decisive moment.
• Less heavy: Is lighter (by 149g or 25 percent) and hence easier to carry around.
• 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 device pairing: Supports NFC for fast wireless image transfer over short distances.
• More affordable: Was introduced into a lower priced category (95 percent cheaper at launch).
• More modern: Reflects 8 years and 5 months of technical progress since the M9 launch.

Advantages of the Leica M9:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Scores markedly higher (6 points) in the DXO overall evaluation.
• Better low-light sensitivity: Can shoot in dim conditions (0.3 stops ISO advantage).
• 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 0.50x).
• More compact: Is smaller (139x80mm vs 129x102mm) and will fit more readily into a bag.
• 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 2009).

If the number of relative strengths (bullet points above) is taken as a guide, the 4000D emerges as the winner of the contest (10 : 8 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.

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 4000D or the M9 perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

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 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.
