Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 5D Mark III and the Leica TL? 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 5D Mark III and the Leica TL. 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 width, height and depth dimensions are rounded to the nearest millimeter.

The TL can be obtained in three different colors (black, silver, titanium), while the 5D Mark III 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 TL is considerably smaller (48 percent) than the Canon 5D Mark III. Moreover, the TL is substantially lighter (60 percent) than the 5D Mark III. It is worth mentioning in this context that the 5D Mark III is splash and dust resistant, while the TL 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. 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 5D Mark III gets 950 shots out of its Canon LP-E6 battery, while the TL can take 400 images on a single charge of its Leica BP-DC13 power pack. The power pack in the TL can be charged via the USB port, which can be very convenient when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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.

The price is, of course, an important factor in any camera decision. 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 TL was launched at a markedly lower price (by 52 percent) than the 5D Mark III, 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon 5D Mark III features a full frame sensor and the Leica TL an APS-C sensor. The sensor area in the TL is 57 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 22.1MP, the 5D Mark III offers a higher resolution than the TL (16.1MP), but the 5D Mark III nevertheless has larger individual pixels (pixel pitch of 6.25μm versus 4.80μm for the TL) due to its larger sensor. However, the TL is a much more recent model (by 4 years and 8 months) than the 5D Mark III, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the TL has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Canon 5D Mark III implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 5D Mark III for good quality output (200 dots per inch) amounts to 28.8 x 19.2 inches or 73.2 x 48.8 cm, for very good quality (250 dpi) 23 x 15.4 inches or 58.5 x 39 cm, and for excellent quality (300 dpi) 19.2 x 12.8 inches or 48.8 x 32.5 cm. The corresponding values for the Leica TL are 24.6 x 16.3 inches or 62.6 x 41.5 cm for good quality, 19.7 x 13.1 inches or 50.1 x 33.2 cm for very good quality, and 16.4 x 10.9 inches or 41.7 x 27.6 cm for excellent quality prints.

The Canon EOS 5D Mark III has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 50-102400. The corresponding ISO settings for the Leica TL are ISO 100 to ISO 12500 (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 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 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 also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (1080/30p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the 5D Mark III has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the TL relies on live view and the rear LCD for framing. That said, the TL can be equipped with an optional viewfinder – the Visoflex (Typ 020). The adjacent table lists some of the other core features of the Canon 5D Mark III and Leica TL along with similar information for a selection of comparators.

One feature that is present on the 5D Mark III, but is missing on the TL 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 5D Mark III writes its imaging data to Compact Flash or SDXC cards, while the TL uses SDXC cards. The 5D Mark III features dual card slots, which can be very useful in case a memory card fails. In contrast, the TL only has one slot.

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 5D Mark III and Leica TL and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 5D Mark III has a microphone port, which is missing on the TL. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

Studio photographers will appreciate that the Canon 5D Mark III (unlike the TL) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 5D Mark III and the TL have been discontinued, but can regularly be found used on ebay. The 5D Mark III was replaced by the Canon 5D Mark IV, while the TL was followed by the Leica TL2. Further information on the features and operation of the 5D Mark III and TL can be found, respectively, in the Canon 5D Mark III Manual (free pdf) or the online Leica TL Manual.

Review summary

So how do things add up? Is there a clear favorite between the Canon 5D Mark III and the Leica TL? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Canon EOS 5D Mark III:

• More detail: Offers more megapixels (22.1 vs 16.1MP) with a 17% higher linear resolution.
• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better sound: Can connect to an external microphone for higher quality sound recording.
• Better sound control: Has a headphone port that enables audio monitoring while recording.
• 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 (6 vs 5 flaps/sec) to capture the decisive moment.
• Longer lasting: Can take more shots (950 versus 400) on a single battery charge.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More heavily discounted: Has been available for much longer (launched in March 2012).

Arguments in favor of the Leica TL:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Larger screen: Has a bigger rear LCD (3.7" vs 3.2") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1230k vs 1040k dots).
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• More compact: Is smaller (134x69mm vs 152x116mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 566g or 60 percent) and is thus easier to take along.
• Easier travel charging: Can be conveniently charged via its USB port.
• More legacy lens friendly: Can use many non-native lenses via adapters.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• More prestigious: Has the Leica luxury appeal, which ensures a high resale value.
• More affordable: Was introduced into a lower priced category (52 percent cheaper at launch).
• More modern: Reflects 4 years and 8 months of technical progress since the 5D Mark III launch.

If the count of relative strengths (bullet points above) is taken as a measure, the match-up finishes in a tie (13 points each). 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 5D Mark III and the Leica TL 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 says little about, for example, the shooting experience and imaging performance of the 5D Mark III and the TL 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 where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major 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.

The review scores listed above should be treated 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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
