Canon M3 vs T2i
The Canon EOS M3 and the Canon EOS Rebel T2i (labelled Canon 550D in some countries) are two digital cameras that were officially introduced, respectively, in February 2015 and February 2010. The M3 is a mirrorless interchangeable lens camera, while the T2i is a DSLR. Both cameras are equipped with an APS-C sensor. The M3 has a resolution of 24 megapixels, whereas the T2i provides 17.9 MP.
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 M3 and the Canon EOS Rebel T2i? 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 physical size and weight of the Canon M3 and the Canon T2i are illustrated 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 dimensions are rounded to the nearest millimeter.
The M3 can be obtained in two different colors (black, white), while the T2i 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 T2i is considerably larger (67 percent) than the Canon M3. Moreover, the T2i is substantially heavier (45 percent) than the M3. In this context, it is worth noting that neither the M3 nor the T2i 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. If you want to switch the focus of the display and review another camera pair, you can 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 listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The M3 was somewhat cheaper (by 3 percent) than the T2i 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.
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 are more costly to manufacture and tend 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.
In terms of chip-set technology, the M3 uses a more advanced image processing engine (DIGIC 6) than the T2i (DIGIC 4), with benefits for noise reduction, color accuracy, and processing speed.
While the two cameras under review share the same sensor size, the M3 offers a higher resolution of 24 megapixels, compared with 17.9 MP of the T2i. This megapixels advantage translates into a 16 percent gain in linear resolution. On the other hand, these sensor specs imply that the M3 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.72μm versus 4.31μm for the T2i). In this context, it should be noted, however, that the M3 is much more recent (by 4 years and 11 months) than the T2i, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.
The resolution advantage of the Canon M3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the M3 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Canon T2i are 25.9 x 17.3 inches or 65.8 x 43.9 cm for good quality, 20.7 x 13.8 inches or 52.7 x 35.1 cm for very good quality, and 17.3 x 11.5 inches or 43.9 x 29.3 cm for excellent quality prints.
The M3 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS M3 has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. The corresponding ISO settings for the Canon EOS Rebel T2i are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-12800.
For many cameras, data on sensor performance has been reported by DXO Mark. 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"). Of the two cameras under review, the M3 has a notably higher overall DXO score than the T2i (overall score 6 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.7 bits higher color depth, 0.3 EV in additional dynamic range, and 0.6 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 are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/30p).
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the T2i 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 T2i, and comparable cameras.

|11.||Canon G7 X||none||n||3.0||1040||tilting||Y||1/2000s||6.5||Y||Y|
One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The M3 has a touchscreen, while the T2i has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The M3 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the T2i does not have a selfie-screen.
Concerning the storage of imaging data, both the M3 and the T2i write their files to SDXC cards. The M3 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the T2i cannot take advantage of Ultra High Speed SD cards.
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 T2i and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the M3 offers wifi support, while the T2i does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the M3 and the T2i have been discontinued, but can regularly be found used on eBay. The T2i was replaced by the Canon T3i, while the M3 was followed by the Canon M6. 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? Is the Canon M3 better than the Canon T2i or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Canon EOS M3:
- More detail: Offers more megapixels (24 vs 17.9MP) with a 16% higher linear resolution.
- Better image quality: Scores markedly higher (6 points) in the DXO overall assessment.
- Better low-light sensitivity: Requires less light for good images (0.6 stops ISO advantage).
- Better jpgs: Has a more modern image processing engine (DIGIC 6 vs DIGIC 4).
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (4.2 vs 3.7 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (111x68mm vs 129x98mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 164g or 31 percent) and hence easier to carry around.
- More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More modern: Reflects 4 years and 11 months of technical progress since the T2i launch.
Arguments in favor of the Canon EOS Rebel T2i:
- Easier framing: Has an optical viewfinder for image composition and settings control.
- Longer lasting: Gets more shots (440 versus 250) out of a single battery charge.
- More heavily discounted: Has been around for much longer (launched in February 2010).
If the number of relative strengths (bullet points above) is taken as a guide, the M3 is the clear winner of the match-up (16 : 3 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. 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.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the M3 or the T2i. 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], 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.

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. 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.
