Canon 40D vs 750D

The Canon EOS 40D and the Canon EOS 750D (labelled Canon T6i in some countries) are two digital cameras that were announced, respectively, in August 2007 and February 2015. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 40D has a resolution of 10.1 megapixels, whereas the 750D provides 24 MP. Read on to find out how these two cameras compare with respect to their body size, their sensors, their features, their input-output connections, and their reception by expert reviewers.

Body comparison: Canon 40D vs 750D

The side-by-side display below illustrates the physical size and weight of the Canon 40D and the Canon 750D. 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 measures 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 40D – represents the basis or 100 percent across all the size and weight measures).

Compare 40D or 750D rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 750D is notably smaller (15 percent) than the Canon 40D. Moreover, the 750D is markedly lighter (32 percent) than the 40D. In this context, it is worth noting that neither the 40D nor the 750D 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Canon EF Lens Catalog.

Concerning battery life, the 40D gets 750 shots out of its BP-511A battery, while the 750D can take 440 images on a single charge of its LP-E17 power pack.

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

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 750D was launched at a markedly lower price (by 42 percent) than the 40D, 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: Canon 40D vs 750D

The size of the sensor inside a digital camera is one of the key determinants 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 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 and have a format factor (sometimes also referred to as "crop factor") of 1.6. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Technology-wise, the 750D uses a more advanced image processing engine (DIGIC 6) than the 40D (DIGIC 3), with benefits for noise reduction, color accuracy, and processing speed.

Canon 40D and Canon 750D sensor measures

While the two cameras under review share the same sensor size, the 750D offers a higher resolution of 24 megapixels, compared with 10.1 MP of the 40D. This megapixels advantage translates into a 54 percent gain in linear resolution. On the other hand, these sensor specs imply that the 750D has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.72μm versus 5.73μm for the 40D). However, it should be noted that the 750D is much more recent (by 7 years and 5 months) than the 40D, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.

The 750D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during video recording.

The Canon EOS 40D has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Canon EOS 750D are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 100-25600..

40D versus 750D MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 750D has a markedly higher DXO score than the 40D (overall score 7 points higher), which will translate into better image quality. The advantage is based on 0.6 bits higher color depth, 0.7 EV in additional dynamic range, and 0.4 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. The 750D indeed provides for movie recording, while the 40D does not. The highest resolution format that the 750D can use is 1080/60p.

 

Feature comparison: Canon 40D vs 750D

Apart from body and sensor, cameras can and do differ across a variety of features. The 40D and the 750D 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 following table reports on some other key feature differences and similarities of the Canon 40D, the Canon 750D, and comparable cameras.

One feature that is present on the 40D, but is missing on the 750D 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 750D has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the 40D does not have a selfie-screen.

The 40D writes its imaging data to Compact Flash cards, while the 750D uses SDXC cards.

Connectivity comparison: Canon 40D vs 750D

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 40D and Canon EOS 750D and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 750D offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 40D does not offer wifi capability.

Both the 40D and the 750D have been discontinued, but can regularly be found used on eBay. The 40D was replaced by the Canon 50D, while the 750D was followed by the Canon 800D.


Review summary: Canon 40D vs 750D

So what is the bottom line? Is the Canon 40D better than the Canon 750D or vice versa? Below is a summary of the relative strengths of each of the two contestants.


Arguments in favor of the Canon EOS 40D:

  • Easier setting verification: Features 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 (6.5 vs 5 flaps/sec) to capture the decisive moment.
  • Longer lasting: Can take more shots (750 versus 440) on a single battery charge.
  • More heavily discounted: Has been available for much longer (launched in August 2007).


Reasons to prefer the Canon EOS 750D:

  • More detail: Has more megapixels (24 vs 10.1MP), which boosts linear resolution by 54%.
  • Better image quality: Scores markedly higher (7 points) in the DXO overall evaluation.
  • More dynamic range: Captures a broader range of light and dark details (0.7 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (0.4 stops ISO advantage).
  • Better jpgs: Has a more modern image processing engine (DIGIC 6 vs DIGIC 3).
  • Broader imaging potential: Can capture not only stills but also 1080/60p video.
  • Better video autofocus: Features on-sensor phase-detection for more confident movie autofocus.
  • 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 selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • More compact: Is smaller (132x101mm vs 146x108mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 267g or 32 percent) and is thus easier to take along.
  • 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 (42 percent cheaper at launch).
  • More modern: Reflects 7 years and 5 months of technical progress since the 40D launch.

If the number of relative strengths (bullet points above) is taken as a guide, the 750D is the clear winner of the contest (17 : 5 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.

40D 05:17 750D

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the 40D or the 750D 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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
