Canon M100 vs T7i
The Canon EOS M100 and the Canon EOS Rebel T7i (labelled Canon 800D in some countries) are two digital cameras that were announced, respectively, in August 2017 and February 2017. The M100 is a mirrorless interchangeable lens camera, while the T7i is a DSLR. Both cameras are equipped with an APS-C sensor. Both cameras offer a resolution of 24 megapixels.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS M100 and the Canon EOS Rebel T7i? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
The side-by-side display below illustrates the physical size and weight of the Canon M100 and the Canon T7i. 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 measures are rounded to the nearest millimeter.
The M100 can be obtained in two different colors (black, white), while the T7i 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 T7i is considerably larger (81 percent) than the Canon M100. Moreover, the T7i is substantially heavier (76 percent) than the M100. In this context, it is worth noting that neither the M100 nor the T7i 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 and compare 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. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will naturally be influenced heavily by the price. 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 M100 was launched at a markedly lower price (by 33 percent) than the T7i, 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.
The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 more expensive and 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.
The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 24 megapixels. This similarity in sensor specs implies that both the M100 and the T7i have the same pixel density, as well as the same pixel size. It should, however, be noted that the 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.
The Canon EOS M100 has a native sensitivity range from ISO 100 to ISO 25600. The corresponding ISO settings for the Canon EOS Rebel T7i are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 100-51200.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. 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 (1080/60p).
Apart from body and sensor, cameras can and do differ across a range of features. For example, the T7i has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the M100 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Canon M100, the Canon T7i, and comparable cameras.

Concerning the storage of imaging data, both the M100 and the T7i 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.
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 M100 and Canon EOS Rebel T7i and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the T7i has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The M100 does not feature such a mic input.
Both the M100 and the T7i have been discontinued, but can regularly be found used on eBay. The T7i was replaced by the Canon T8i, while the M100 was followed by the Canon M200. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So how do things add up? Which of the two cameras – the Canon M100 or the Canon T7i – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Canon EOS M100:
- More compact: Is smaller (108x67mm vs 131x100mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 230g or 43 percent) and hence easier to carry around.
- More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
- More affordable: Was introduced into a lower priced category (33 percent cheaper at launch).
- More modern: Is somewhat more recent (announced 6 months after the T7i).
Advantages of the Canon EOS Rebel T7i:
- Better sound: Can connect to an external microphone for higher quality sound recording.
- Easier framing: Has an optical viewfinder for image composition and settings control.
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Longer lasting: Gets more shots (600 versus 295) out of a single battery charge.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- More heavily discounted: Has been on the market for longer (launched in February 2017).
If the count of relative strengths (bullet points above) is taken as a measure, the T7i comes out slightly ahead of the M100 (6 : 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. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
How about other alternatives? Do the specifications of the Canon M100 and the Canon T7i place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.
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 M100 or the T7i perform in practice. 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 following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

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. Thus, a score needs to be put into the context of the launch date and the launch price 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.
