YI M1 versus Canon T7i
The YI M1 and the Canon EOS Rebel T7i (labelled Canon 800D in some countries) are two digital cameras that were officially introduced, respectively, in September 2016 and February 2017. The M1 is a mirrorless interchangeable lens camera, while the T7i is a DSLR. The cameras are based on a Four Thirds (M1) and an APS-C sensor. The YI has a resolution of 20.2 megapixel, whereas the Canon provides 24 MP.
The physical size and weight of the YI M1 and the Canon T7i are illustrated in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the M1 – 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 T7i is considerably larger (80 percent) than the YI M1. Moreover, the T7i is substantially heavier (89 percent) than the M1. In this context, it is worth noting that neither the M1 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can find an overview of optics for the two cameras in the Micro Four Thirds Lens Catalog (M1) and the Canon EF Lens Catalog (T7i). Mirrorless cameras, such as the YI M1, have moreover the advantage that they have a relatively short flange to focal plane distance and can thus use many lenses from other systems via adapters.
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 M1 was launched at a markedly lower price (by 53 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.
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 are more costly to manufacture and tent to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the YI M1 features a Four Thirds sensor and the Canon T7i an APS-C sensor. The sensor area in the T7i is 48 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.6. The sensor in the M1 has a native 4:3 aspect ratio, while the one in the T7i offers a 3:2 aspect.
With 24MP, the T7i offers a higher resolution than the M1 (20.2MP), but the T7i nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 3.34μm for the M1) due to its larger sensor. Moreover, the T7i is a somewhat more recent model (by 4 months) than the M1, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.
Consistent information on actual sensor performance is available from DXO Mark for most 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"). 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, but the M1 provides a higher video resolution than the T7i. It can shoot video footage at 4K/30p, while the Canon is limited to 1080/60p.
Beyond 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 M1 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the YI M1, the Canon T7i, and comparable cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Both the M1 and the T7i 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 M1 does not have a direct predecessor.
So how do things add up? Is the YI M1 better than the Canon T7i or vice versa? The listing below highlights the relative strengths of the two models.
Arguments in favor of the YI M1:
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
- More compact: Is smaller (114x64mm vs 131x100mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 251g or 47 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 (53 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in September 2016).
Reasons to prefer the Canon EOS Rebel T7i:
- More detail: Has more megapixels (24 vs 20.2MP), which boosts linear resolution by 11%.
- Better low-light imaging: Features bigger pixels on a larger sensor for better high-ISO images.
- Easier framing: Has an optical viewfinder for image framing and settings control.
- More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
- Faster burst: Shoots at higher frequency (6 vs 5 flaps/sec) to capture the decisive moment.
- Longer lasting: Gets more shots (600 versus 450) out of a single battery charge.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- More modern: Was introduced somewhat (4 months) more recently.
If the count of individual advantages (bullet points above) is taken as a guide, the T7i emerges as the winner of the match-up (8 : 6 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.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the M1 and the T7i in practical situations. 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. This is why hands-on reviews by experts are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites.

The above review scores should be interpreted with care, though. The ratings are only valid when refering to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
In case you are interested in seeing how other cameras pair up, just make your choice using the following search menu. Alternatively, you can follow any of the listed hyperlinks for comparisons that others found interesting. If the camera you are interested in is not available, please send me an email, and I will try to add information on that model to the database.
