Canon M3 vs T6i
The Canon EOS M3 and the Canon EOS Rebel T6i (labelled Canon 750D in some countries) are two digital cameras that were revealed to the public in February 2015. The M3 is a mirrorless interchangeable lens camera, while the T6i is a DSLR. Both cameras are equipped with an APS-C sensor. Both cameras offer a resolution of 24 megapixels. 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 M3 vs T6i
An illustration of the physical size and weight of the Canon M3 and the Canon T6i is provided 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 width, height and depth measures 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 M3 – 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 T6i is considerably larger (77 percent) than the Canon M3. Moreover, the T6i is substantially heavier (52 percent) than the M3. In this context, it is worth noting that neither the M3 nor the T6i 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 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.

Any camera decision will obviously take relative prices into account. 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 M3 was somewhat cheaper (by 9 percent) than the T6i at launch, but both cameras fall into the same price category. 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 M3 vs T6i
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 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 M3 and the T6i have the same pixel density, as well as the same pixel size. Moreover, the two cameras were released in close succession, so that their sensors are from the same technological generation.
The Canon EOS M3 has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600.. The Canon EOS Rebel T6i offers exactly the same ISO settings.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar 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 T6i provides a faster frame rate than the M3. It can shoot movie footage at 1080/60p, while the M3 is limited to 1080/30p.
Feature comparison: Canon M3 vs T6i
Beyond body and sensor, cameras can and do differ across a range of features. For example, the T6i has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the M3 relies on live view and the rear LCD for framing. That said, the M3 can be equipped with an optional viewfinder – the EVF-DC1. The following table reports on some other key feature differences and similarities of the Canon M3, the Canon T6i, and comparable cameras.

Connectivity comparison: Canon M3 vs T6i
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 M3 and Canon EOS Rebel T6i and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Review summary: Canon M3 vs T6i
So what is the bottom line? Is the Canon M3 better than the Canon T6i or vice versa? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Canon EOS M3:
- Better low-light sensitivity: Requires less light for good images (0.3 stops ISO advantage).
- More compact: Is smaller (111x68mm vs 132x101mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 189g or 34 percent) and hence easier to carry around.
- More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
Arguments in favor of the Canon EOS Rebel T6i:
- Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
- 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 (5 vs 4.2 flaps/sec) to capture the decisive moment.
- Longer lasting: Gets more shots (440 versus 250) out of a single battery charge.
If the count of relative strengths (bullet points above) is taken as a measure, the T6i comes out slightly ahead of the M3 (5 : 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.
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 M3 and the T6i 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.

Care should be taken when interpreting the review scores above, 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.
