Canon 1D Mark III versus Canon T5i

The Canon EOS-1D Mark III and the Canon EOS Rebel T5i (labelled Canon 700D in some countries) are two digital cameras that were officially introduced, respectively, in February 2007 and March 2013. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-H (1D Mark III) and an APS-C (T5i) sensor. The 1D Mark III has a resolution of 10.1 megapixel, whereas the T5i provides 17.9 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon 1D Mark III vs Canon T5i

The physical size and weight of the Canon 1D Mark III and the Canon T5i 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. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the 1D Mark III – represents 100 percent across all the size and weight measures).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon T5i is considerably smaller (46 percent) than the Canon 1D Mark III. Moreover, the T5i is substantially lighter (50 percent) than the 1D Mark III. It is worth mentioning in this context that the 1D Mark III is splash and dust resistant, while the T5i 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 (as in the 1D Mark III) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (T5i). You can find a comprehensive overview of suitable optics in the Canon EF Lens Catalog.

Concerning battery life, the 1D Mark III gets 2200 shots out of its LP-E4 battery, while the T5i can take 440 images on a single charge of its LP-E8 power pack.

Any camera purchase 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 T5i was launched at a markedly lower price (by 86 percent) than the 1D Mark III, 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: Canon 1D Mark III vs Canon T5i

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 1D Mark III features an APS-H sensor and the Canon T5i an APS-C sensor. The sensor area in the T5i is 37 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 and 1.6. 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.

Canon 1D Mark III and Canon T5i sensor measures

Despite having a smaller sensor, the T5i offers a higher resolution of 17.9 megapixel, compared with 10.1 MP of the 1D Mark III. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.31μm versus 7.21μm for the 1D Mark III). However, it should be noted that the T5i is much more recent (by 6 years) than the 1D Mark III, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

1D Mark III versus T5i MP

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"). Of the two cameras under review, the 1D Mark III has a notably higher overall DXO score than the T5i (overall score 10 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1 bits higher color depth, 0.5 EV in additional dynamic range, and 0.7 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The T5i indeed provides for movie recording, while the 1D Mark III does not. The highest resolution format that the T5i can use is 1080/30p.

 

Feature comparison: Canon 1D Mark III vs Canon T5i

Beyond body and sensor, cameras can and do differ across a range of features. The 1D Mark III and the T5i 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 adjacent table lists some of the other core features of the Canon 1D Mark III and Canon T5i along with similar information for a selection of comparators.

Review summary: Canon 1D Mark III vs Canon T5i

So how do things add up? Which of the two cameras – the Canon 1D Mark III or the Canon T5i – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.


Advantages of the Canon EOS-1D Mark III:

  • Better image quality: Scores markedly higher (10 points) in the DXO overall assessment.
  • Better low-light sensitivity: Requires less light for good images (0.7 stops ISO advantage).
  • Easier setting verification: Has an LCD display on top to control shooting parameters.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (10 vs 5 flaps/sec) to capture the decisive moment.
  • Longer lasting: Can take more shots (2200 versus 440) on a single battery charge.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • More heavily discounted: Has been available for much longer (launched in February 2007).


Arguments in favor of the Canon EOS Rebel T5i:

  • More detail: Has more megapixels (17.9 vs 10.1MP), which boosts linear resolution by 33%.
  • Broader imaging potential: Can capture not only stills but also 1080/30p video.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • More compact: Is smaller (133x100mm vs 156x156.6mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 575g or 50 percent) and is thus easier to take along.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (86 percent cheaper at launch).
  • More modern: Reflects 6 years of technical progress since the 1D Mark III launch.

If the count of individual advantages (bullet points above) is taken as a guide, the T5i emerges as the winner of the match-up (10 : 8 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.

1D Mark III 08:10 T5i

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 1D Mark III or the T5i handle or 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. This is where reviews by experts come in.

Care should be taken when interpreting the review scores above, 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.
