Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 100D and the Leica TL2? 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 side-by-side display below illustrates the physical size and weight of the Canon 100D and the Leica TL2. 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 100D can be obtained in two different colors (black, white), while the TL2 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 TL2 is notably smaller (13 percent) than the Canon 100D. Moreover, the TL2 is slightly lighter (2 percent) than the 100D. In this context, it is worth noting that neither the 100D nor the TL2 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the 100D gets 380 shots out of its Canon LP-E12 battery, while the TL2 can take 250 images on a single charge of its Leica BP-DC13 power pack. The power pack in the TL2 can be charged via the USB port, which can be very convenient when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

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 100D was launched at a markedly lower price (by 72 percent) than the TL2, 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the TL2 is 12 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (100D) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 24.1MP, the TL2 offers a higher resolution than the 100D (17.9MP), but the TL2 has smaller individual pixels (pixel pitch of 3.92μm versus 4.31μm for the 100D). Yet, the TL2 is a much more recent model (by 4 years and 3 months) than the 100D, 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 TL2 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Leica TL2 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the TL2 for good quality output (200 dots per inch) amounts to 30.1 x 20.1 inches or 76.4 x 51 cm, for very good quality (250 dpi) 24.1 x 16.1 inches or 61.1 x 40.8 cm, and for excellent quality (300 dpi) 20 x 13.4 inches or 50.9 x 34 cm. The corresponding values for the Canon 100D are 25.9 x 17.3 inches or 65.8 x 43.9 cm for good quality, 20.7 x 13.8 inches or 52.7 x 35.1 cm for very good quality, and 17.3 x 11.5 inches or 43.9 x 29.3 cm for excellent quality prints.

The 100D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS 100D has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. The corresponding ISO settings for the Leica TL2 are ISO 100 to ISO 50000 (no boost).

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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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. 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. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the TL2 provides a better video resolution than the 100D. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the 100D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the TL2 relies on live view and the rear LCD for framing. That said, the TL2 can be equipped with an optional viewfinder – the Visoflex (Typ 020). The adjacent table lists some of the other core features of the Canon 100D and Leica TL2 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The 100D has one, while the TL2 does not. While the built-in flash of the 100D is not very powerful, it can at times be useful as a fill-in light.

Concerning the storage of imaging data, both the 100D and the TL2 write their files to SDXC cards. The TL2 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the 100D can use UHS-I cards (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 100D and Leica TL2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 100D has a microphone port, which is missing on the TL2. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

Both the 100D and the TL2 have been discontinued, but can regularly be found used on ebay. The 100D was replaced by the Canon 200D, while the TL2 does not have a direct successor. Further information on the features and operation of the 100D and TL2 can be found, respectively, in the Canon 100D Manual (free pdf) or the online Leica TL2 Manual.

Review summary

So what is the bottom line? Is the Canon 100D better than the Leica TL2 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 100D:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• 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.
• Easier framing: Has an optical viewfinder for image composition and settings control.
• Longer lasting: Can take more shots (380 versus 250) on a single battery charge.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• More affordable: Was introduced into a lower priced category (72 percent cheaper at launch).
• More heavily discounted: Has been available for much longer (launched in March 2013).

Advantages of the Leica TL2:

• More detail: Has more megapixels (24.1 vs 17.9MP), which boosts linear resolution by 16%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
• Larger screen: Has a bigger rear LCD (3.7" vs 3.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1230k vs 1040k dots).
• Faster burst: Shoots at higher frequency (7 vs 4.9 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (134x69mm vs 117x91mm) and will fit more readily into a bag.
• Easier travel charging: Can be conveniently charged via its USB port.
• More legacy lens friendly: Can use many non-native lenses via adapters.
• Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
• More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
• More modern: Reflects 4 years and 3 months of technical progress since the 100D launch.

If the count of relative strengths (bullet points above) is taken as a measure, the TL2 is the clear winner of the contest (14 : 8 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. 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 100D and the Leica TL2 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 comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the 100D or the TL2 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 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 (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.

The review scores listed above should be treated 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 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.
