Canon T7i versus Canon M100

The Canon EOS Rebel T7i (called Canon 800D in some regions) and the Canon EOS M100 are two digital cameras that were officially introduced, respectively, in February 2017 and August 2017. The T7i is a DSLR, while the EOS M100 is a mirrorless interchangeable lens camera. Both cameras are equipped with an APS-C sensor. Both cameras offer a resolution of 24 megapixel.

Body comparison

An illustration of the physical size and weight of the Canon T7i and the Canon M100 is provided in the side-by-side display below. 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 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 T7i – 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 M100 is considerably smaller (45 percent) than the Canon T7i. Moreover, the EOS M100 is substantially lighter (43 percent) than the T7i. Cameras that are intended for semi-professional or professional use are sometimes a bit bulkier in order to provide them with the necessary ruggedness. In this context, it is worth noting that neither the T7i nor the EOS M100 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. Hence, you might want to study the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The EOS M100 was launched at a markedly lower price (by 33 percent) than the T7i, 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

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 tent 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.

Sensor size

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 24 megapixel. This similarity in sensor specs implies that both the T7i and the EOS M100 have the same pixel density, as well as the same pixel size. It should, however, be noted that the EOS M100 is a somewhat more recent model (by 6 months) than the T7i, and its sensor might have benefitted from technological advances during this time.

Consistent information on actual sensor performance is available from DXO Mark for most cameras. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/60p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the T7i has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the EOS M100 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon T7i and Canon M100 in connection with corresponding information for a sample of similar cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

Both the T7i and the EOS M100 are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The T7i replaced the earlier Canon T6i, while the EOS M100 followed on from the Canon M10.

Summary

So what is the bottom line? Which of the two cameras – the Canon T7i or the Canon M100 – 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 Rebel T7i:

  • Easier framing: Has an optical viewfinder for image framing and settings control.
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • Longer lasting: Can take more shots (600 versus 295) on a single battery charge.
  • More heavily discounted: Has been on the market for longer (launched in February 2017).

Advantages of the Canon EOS M100:

  • More compact: Is smaller (108x67mm vs 131x100mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 230g or 43 percent) and is thus easier to take along.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • More affordable: Was introduced into a lower priced category (33 percent cheaper at launch).
  • More modern: Was introduced somewhat (6 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the EOS M100 comes out slightly ahead of the T7i (5 : 4 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.

T7i 04:05 EOS M100

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the T7i or the EOS M100. 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 why expert reviews are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The review scores listed above should be treated with care, though. The ratings are only valid when refering 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
