Canon 750D versus Canon 5D Mark III

The Canon EOS 750D (called Canon T6i in some regions) and the Canon EOS 5D Mark III are two digital cameras that were officially introduced, respectively, in February 2015 and March 2012. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (750D) and a full frame (5D Mark III) sensor. The 750D has a resolution of 24 megapixel, whereas the 5D Mark III provides 22.1 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 750D vs Canon 5D Mark III

The physical size and weight of the Canon 750D and the Canon 5D Mark III are illustrated 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 dimensions are rounded to the nearest millimeter. You can also toggle the display 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 750D – represents the basis or 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 5D Mark III is notably larger (32 percent) than the Canon 750D. Moreover, the 5D Mark III is substantially heavier (71 percent) than the 750D. It is noteworthy in this context that the 5D Mark III is splash and dust-proof, while the 750D 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 5D Mark III) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (750D). You can find a comprehensive overview of suitable optics in the Canon EF Lens Catalog.

Concerning battery life, the 750D gets 440 shots out of its LP-E17 battery, while the 5D Mark III can take 950 images on a single charge of its LP-E6 power pack.

The camera’s price is obviously a critical decision-making factor. 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 750D was launched at a markedly lower price (by 79 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Canon 750D vs Canon 5D Mark III

The size of the imaging sensor is a crucial determinant 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. 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 750D features an APS-C sensor and the Canon 5D Mark III a full frame sensor. The sensor area in the 5D Mark III 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.

In terms of underlying technology, both cameras are build around CMOS sensors.

Canon 750D and Canon 5D Mark III sensor measures

Despite having a smaller sensor, the Canon 750D offers a higher resolution of 24 megapixel, compared with 22.1 MP of the Canon 5D 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 3.72μm versus 6.25μm for the 5D Mark III). However, it should be noted that the 750D is much more recent (by 2 years and 11 months) than the 5D Mark III, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

750D versus 5D Mark III MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under consideration, the 5D Mark III has a markedly higher DXO score than the 750D (overall score 10 points higher), which will translate into better image quality. The advantage is based on 1.3 bits higher color depth, 0.3 EV of lower dynamic range, and 1.3 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the 750D provides a higher frame rate than the 5D Mark III. It can shoot video footage at 1080/60p, while the 5D Mark III is limited to 1080/30p.

 

Feature comparison: Canon 750D vs Canon 5D Mark III

Apart from body and sensor, cameras can and do differ across a variety of features. The 750D and the 5D Mark III 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 750D and Canon 5D Mark III along with similar information for a selection of comparators.

Both the 750D and the 5D Mark III 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 750D was followed by the Canon 800D.

Review summary: Canon 750D vs Canon 5D Mark III

So what is the bottom line? Which of the two cameras – the Canon 750D or the Canon 5D Mark III – has the upper hand? The listing below highlights the relative strengths of the two models.


Advantages of the Canon EOS 750D:

  • Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • More flexible LCD: Has 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 compact: Is smaller (132x101mm vs 152x116mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 395g or 42 percent) and hence easier to carry around.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More affordable: Was introduced into a lower priced category (79 percent cheaper at launch).
  • More modern: Reflects 2 years and 11 months of technical progress since the 5D Mark III launch.


Arguments in favor of the Canon EOS 5D Mark III:

  • Better image quality: Scores markedly higher (10 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.3 bits more color depth).
  • Better low-light sensitivity: Can shoot in dim conditions (1.3 stops ISO advantage).
  • Easier setting verification: Has a control panel on top to check shooting parameters.
  • Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (6 vs 5 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (950 versus 440) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • More heavily discounted: Has been around for much longer (launched in March 2012).

If the count of relative strengths (bullet points above) is taken as a measure, the 5D Mark III emerges as the winner of the match-up (10 : 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.

750D 08:10 5D Mark III

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 750D or the 5D Mark III. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is where reviews by experts come in. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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, please note that some of the review sites have changed their methodology and reporting over time.
