Canon 100D vs 70D

The Canon EOS 100D (called Canon SL1 in some regions) and the Canon EOS 70D are two digital cameras that were announced, respectively, in March 2013 and July 2013. 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 70D provides 20 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 70D

The side-by-side display below illustrates the physical size and weight of the Canon 100D and the Canon 70D. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

The 100D can be obtained in two different colors (black, white), while the 70D 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 70D is notably larger (36 percent) than the Canon 100D. Moreover, the 70D is substantially heavier (86 percent) than the 100D. It is noteworthy in this context that the 70D is splash and dust-proof, while the 100D 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. 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 100D gets 380 shots out of its LP-E12 battery, while the 70D can take 920 images on a single charge of its LP-E6 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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 manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The 100D was launched at a markedly lower price (by 54 percent) than the 70D, 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 100D vs 70D

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. 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 tend to be associated with larger, more expensive camera bodies and lenses.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the 70D is 2 percent bigger. They nevertheless have the same format factor of 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Technology-wise, the 70D uses a more advanced image processing engine (DIGIC 5+) than the 100D (DIGIC 5), with benefits for noise reduction, color accuracy, and processing speed.

Canon 100D and Canon 70D sensor measures

With 20MP, the 70D offers a higher resolution than the 100D (17.9MP), but the 70D has smaller individual pixels (pixel pitch of 4.11μm versus 4.31μm for the 100D). Yet, the 70D is a somewhat more recent model (by 3 months) than the 100D, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The Canon EOS 100D has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600.. The Canon EOS 70D offers exactly the same ISO settings.

100D versus 70D MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 consideration, the 70D has a markedly higher DXO score than the 100D (overall score 5 points higher), which will translate into better image quality. The advantage is based on 0.7 bits higher color depth, 0.3 EV in additional dynamic range, and 0.1 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 cannot only take still pictures, but also record videos. 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: Canon 100D vs 70D

Apart from body and sensor, cameras can and do differ across a variety of features. The 100D and the 70D 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 viewfinder in the 70D offers a wider field of view (98%) than the one in the 100D (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the 70D has a higher magnification (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 adjacent table lists some of the other core features of the Canon 100D and Canon 70D along with similar information for a selection of comparators.

One feature that is present on the 70D, but is missing on the 100D 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 70D 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 100D does not have a selfie-screen.

Concerning the storage of imaging data, both the 100D and the 70D write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

 

Connectivity comparison: Canon 100D vs 70D

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 70D and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 70D offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 100D does not offer wifi capability.

Both the 100D and the 70D have been discontinued, but can regularly be found used on eBay. The 100D was replaced by the Canon 200D, while the 70D was followed by the Canon 80D. Further information on the two cameras, as well as related accessories, can be found on the Canon website.


Review summary: Canon 100D vs 70D

So how do things add up? Which of the two cameras – the Canon 100D or the Canon 70D – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.


Arguments in favor of the Canon EOS 100D:

  • More compact: Is smaller (117x91mm vs 139x104mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 348g or 46 percent) and hence easier to carry around.
  • More affordable: Was introduced into a lower priced category (54 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in March 2013).


Advantages of the Canon EOS 70D:

  • More detail: Has more megapixels (20 vs 17.9MP), which boosts linear resolution by 6%.
  • Better image quality: Scores markedly higher (5 points) in the DXO overall evaluation.
  • Better jpgs: Has a more modern image processing engine (DIGIC 5+ vs DIGIC 5).
  • More complete view: Has a viewfinder with a larger field of view (98% vs 95%).
  • 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.
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (7 vs 4.9 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (920 versus 380) out of a single battery charge.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • More modern: Was introduced somewhat (3 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the 70D is the clear winner of the contest (14 : 4 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.

100D 04:14 70D

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the 100D and the 70D in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Notes: ++) highly recommended; +) recommended; o) reviewed; -) not available.

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
