Canon 100D vs 40D
The Canon EOS 100D (called Canon SL1 in some regions) and the Canon EOS 40D are two digital cameras that were officially introduced, respectively, in March 2013 and August 2007. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 100D has a resolution of 17.9 megapixels, whereas the 40D provides 10.1 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 100D vs 40D
The physical size and weight of the Canon 100D and the Canon 40D 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.
The 100D can be obtained in two different colors (black, white), while the 40D 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 Canon 40D is considerably larger (48 percent) than the Canon 100D. Moreover, the 40D is substantially heavier (102 percent) than the 100D. In this context, it is worth noting that neither the 100D nor the 40D 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.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 100D was launched at a markedly lower price (by 58 percent) than the 40D, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
Sensor comparison: Canon 100D vs 40D
The size of the imaging sensor is a crucial determinant of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 associated with larger, more expensive camera bodies 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.
In terms of chip-set technology, the 100D uses a more advanced image processing engine (DIGIC 5) than the 40D (DIGIC 3), with benefits for noise reduction, color accuracy, and processing speed.
While the two cameras under review share the same sensor size, the 100D offers a higher resolution of 17.9 megapixels, compared with 10.1 MP of the 40D. This megapixels advantage translates into a 33 percent gain in linear resolution. On the other hand, these sensor specs imply that the 100D has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.31μm versus 5.73μm for the 40D). In this context, it should be noted, however, that the 100D is much more recent (by 5 years and 7 months) than the 40D, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.
The 100D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during video recording.
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 Canon EOS 40D are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 100-3200..
For many cameras, data on sensor performance has been reported by DXO Mark. 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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. 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 cannot only take still pictures, but also record videos. The 100D indeed provides movie recording capabilities, while the 40D does not. The highest resolution format that the 100D can use is 1080/30p.
Feature comparison: Canon 100D vs 40D
Apart from body and sensor, cameras can and do differ across a variety of features. The 100D and the 40D 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 viewfinders of both cameras offer the same field of view (95%), but the viewfinder of the 40D has a higher magnification than the one of the 100D (0.59x vs 0.54x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Canon 100D and Canon 40D in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The 100D has a touchscreen, while the 40D has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
The 100D writes its imaging data to SDXC cards, while the 40D uses Compact Flash cards.
Connectivity comparison: Canon 100D vs 40D
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 Canon EOS 40D and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon 40D (unlike the 100D) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 100D and the 40D have been discontinued, but can regularly be found used on eBay. The 40D was replaced by the Canon 50D, while the 100D was followed by the Canon 200D. Further information on the two cameras, as well as related accessories, can be found on the official Canon website.
Review summary: Canon 100D vs 40D
So how do things add up? Is the Canon 100D better than the Canon 40D or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Canon EOS 100D:
- More detail: Offers more megapixels (17.9 vs 10.1MP) with a 33% higher linear resolution.
- Better jpgs: Has a more modern image processing engine (DIGIC 5 vs DIGIC 3).
- Broader imaging potential: Can record not only still images but also 1080/30p movies.
- 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).
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- More compact: Is smaller (117x91mm vs 146x108mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 415g or 50 percent) and hence easier to carry around.
- More affordable: Was introduced into a lower priced category (58 percent cheaper at launch).
- More modern: Reflects 5 years and 7 months of technical progress since the 40D launch.
Advantages of the Canon EOS 40D:
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.59x vs 0.54x).
- Easier setting verification: Features a control panel on top to check shooting parameters.
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Faster burst: Shoots at higher frequency (6.5 vs 4.9 flaps/sec) to capture the decisive moment.
- Longer lasting: Gets more shots (750 versus 380) out of a single battery charge.
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- More heavily discounted: Has been around for much longer (launched in August 2007).
If the number of relative strengths (bullet points above) is taken as a guide, the 100D emerges as the winner of the contest (10 : 7 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.
Do the specifications of the Canon 100D and the Canon 40D place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing.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 100D or the 40D perform in practice. 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.

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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
