Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 450D and the Canon EOS M3? 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 450D and the Canon M3 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. 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.
The M3 can be obtained in two different colors (black, white), while the 450D 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 M3 is considerably smaller (40 percent) than the Canon 450D. Moreover, the M3 is markedly lighter (30 percent) than the 450D. In this context, it is worth noting that neither the 450D nor the M3 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 naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The M3 was launched at a somewhat lower price (by 15 percent) than the 450D, which makes it more attractive for photographers on a tight budget. 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 imaging sensor is a crucial determinant 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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, but their sensors differ slightly in size. The sensor area in the M3 is 1 percent bigger. They nevertheless have the same format factor of 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Technology-wise, the M3 uses a more advanced image processing engine (DIGIC 6) than the 450D (DIGIC 3), with benefits for noise reduction, color accuracy, and processing speed.
With 24MP, the M3 offers a higher resolution than the 450D (12.2MP), but the M3 has smaller individual pixels (pixel pitch of 3.72μm versus 5.19μm for the 450D). Yet, the M3 is a much more recent model (by 7 years) than the 450D, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.
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 450D are 21.4 x 14.2 inches or 54.3 x 36.2 cm for good quality, 17.1 x 11.4 inches or 43.4 x 28.9 cm for very good quality, and 14.2 x 9.5 inches or 36.2 x 24.1 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 450D has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Canon EOS M3 are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 100-25600.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 consideration, the M3 offers substantially better image quality than the 450D (overall score 11 points higher). The advantage is based on 0.9 bits higher color depth, 1 EV in additional dynamic range, and 0.8 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.
|Canon G1 X Mark II||1.5-inch||13.0||4160||3120||1080/30p||21.5||10.8||581||58|
|Canon G7 X||1-inch||20.0||5472||3648||1080/60p||23.0||12.7||556||71|
|Canon G1 X||1.5-inch||14.2||4352||3264||1080/24p||21.7||10.8||644||60|
Many modern cameras are not only capable of taking still images, but can also record movies. The M3 indeed provides for movie recording, while the 450D does not. The highest resolution format that the M3 can use is 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the 450D 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 450D, the Canon M3, and comparable cameras.
|Canon G1 X Mark II||optional||n||3.0||1040||tilting||Y||1/4000s||5.2||Y||Y|
|Canon G7 X||none||n||3.0||1040||tilting||Y||1/2000s||6.5||Y||Y|
|Canon G1 X||optical||n||3.0||922||Swivel||n||1/4000s||1.9||Y||Y|
One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The M3 has a touchscreen, while the 450D has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The M3 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the 450D does not have a selfie-screen.
The 450D writes its imaging data to SDHC cards, while the M3 uses SDXC cards. The M3 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the 450D 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 450D and Canon EOS M3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.
| WiFi |
|Canon G1 X Mark II||Y||stereo||mono||-||-||mini||2.0||Y||Y||-|
|Canon G7 X||-||stereo||mono||-||-||micro||2.0||Y||Y||-|
|Canon G1 X||Y||stereo||mono||-||-||mini||2.0||-||-||-|
It is notable that the M3 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 450D does not provide wifi capability.
Both the 450D and the M3 have been discontinued, but can regularly be found used on eBay. The 450D was replaced by the Canon 500D, 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 what conclusions can be drawn? Is there a clear favorite between the Canon 450D and the Canon M3? Which camera is better? The listing below highlights the relative strengths of the two models.

If the count of individual advantages (bullet points above) is taken as a guide, the M3 is the clear winner of the contest (20 : 3 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 450D or the M3. 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 hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 above review scores should be interpreted with care, 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
