Canon 30D vs Canon M
The Canon EOS 30D and the Canon EOS M are two digital cameras that were revealed to the public, respectively, in February 2006 and July 2012. The 30D is a DSLR, while the Canon M is a mirrorless interchangeable lens camera. Both cameras are equipped with an APS-C sensor. The 30D has a resolution of 8.2 megapixels, whereas the Canon M 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 30D and the Canon EOS M? 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 30D and the Canon M 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 Canon M can be obtained in two different colors (black, white), while the 30D 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 M is considerably smaller (53 percent) than the Canon 30D. Moreover, the Canon M is substantially lighter (62 percent) than the 30D. In this context, it is worth noting that neither the 30D nor the Canon M 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. 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 obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Canon M was launched at a markedly lower price (by 57 percent) than the 30D, 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.
The size of the sensor inside a digital camera is one of the key determinants 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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, but their sensors differ slightly in size. The sensor area in the Canon M is 2 percent smaller. 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 Canon M uses a more advanced image processing engine (DIGIC V) than the 30D (DIGIC 2), with benefits for noise reduction, color accuracy, and processing speed.
Despite having a slightly smaller sensor, the Canon M offers a higher resolution of 17.9 megapixels, compared with 8.2 MP of the 30D. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.31μm versus 6.42μm for the 30D). However, it should be noted that the Canon M is much more recent (by 6 years and 5 months) than the 30D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The resolution advantage of the Canon M implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Canon M for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inches or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inches or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inches or 43.9 x 29.3 cm. The corresponding values for the Canon 30D are 17.5 x 11.7 inches or 44.5 x 29.7 cm for good quality, 14 x 9.3 inches or 35.6 x 23.7 cm for very good quality, and 11.7 x 7.8 inches or 29.7 x 19.8 cm for excellent quality prints.
The Canon M has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS 30D has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Canon EOS M are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 100-25600.
For many cameras, data on sensor performance has been reported by DXO Mark. 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. Of the two cameras under consideration, the Canon M has a markedly higher DXO score than the 30D (overall score 6 points higher), which will translate into better image quality. The advantage is based on 0.6 bits higher color depth, 0.4 EV in additional dynamic range, and 0.2 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 can also record movies. The Canon M indeed provides for movie recording, while the 30D does not. The highest resolution format that the Canon M can use is 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the 30D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the Canon M 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 30D, the Canon M, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The 30D has one, while the Canon M does not. While the built-in flash of the 30D is not very powerful, it can at times be useful as a fill-in light.
The 30D writes its imaging data to Compact Flash cards, while the Canon M uses SDXC 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 30D and Canon EOS M and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon 30D (unlike the Canon M) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 30D and the Canon M have been discontinued, but can regularly be found used on eBay. The 30D was replaced by the Canon 40D, while the Canon M was followed by the Canon EOS M3. 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 30D and the Canon M? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Canon EOS 30D:
- Easier framing: Has an optical viewfinder for image composition and settings control.
- Easier setting verification: Features an LCD display on top to control shooting parameters.
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Faster burst: Shoots at higher frequency (5 vs 4.3 flaps/sec) to capture the decisive moment.
- Longer lasting: Can take more shots (750 versus 230) on a single battery charge.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- More heavily discounted: Has been available for much longer (launched in February 2006).
Reasons to prefer the Canon EOS M:
- More detail: Has more megapixels (17.9 vs 8.2MP), which boosts linear resolution by 48%.
- Better image quality: Scores markedly higher (6 points) in the DXO overall evaluation.
- Better jpgs: Has a more modern image processing engine (DIGIC V vs DIGIC 2).
- Broader imaging potential: Can capture not only stills but also 1080/30p video.
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- More compact: Is smaller (109x66mm vs 144x106mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 487g or 62 percent) and is thus easier to take along.
- More legacy lens friendly: Can use many non-native lenses via adapters.
- More affordable: Was introduced into a lower priced category (57 percent cheaper at launch).
- More modern: Reflects 6 years and 5 months of technical progress since the 30D launch.
If the number of relative strengths (bullet points above) is taken as a guide, the Canon M is the clear winner of the contest (13 : 8 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 30D and the Canon M place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens 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 says little about, for example, the shooting experience and imaging performance of the 30D and the Canon M 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.
This is where reviews by experts come in. 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 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 comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
