Canon 1D vs M3

The Canon EOS-1D and the Canon EOS M3 are two digital cameras that were announced, respectively, in September 2001 and February 2015. The 1D is a DSLR, while the M3 is a mirrorless interchangeable lens camera. The cameras are based on an APS-H (1D) and an APS-C (M3) sensor. The 1D has a resolution of 4.1 megapixels, whereas the M3 provides 24 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-1D 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.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Canon 1D and the Canon M3. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. 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 1D 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 (69 percent) than the Canon 1D. Moreover, the M3 is substantially lighter (77 percent) than the 1D. It is worth mentioning in this context that the 1D is splash and dust resistant, while the M3 does not feature any corresponding weather-sealing.

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.

Concerning battery life, the 1D gets 500 shots out of its NP-E3 battery, while the M3 can take 250 images on a single charge of its LP-E17 power pack. As can be seen in the images above, the 1D has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power.

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 launched at a markedly lower price (by 90 percent) than the 1D, 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 1D features an APS-H sensor and the Canon M3 an APS-C sensor. The sensor area in the M3 is 39 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 and 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 1D (DIGIC), with benefits for noise reduction, color accuracy, and processing speed.

Despite having a smaller sensor, the M3 offers a higher resolution of 24 megapixels, compared with 4.1 MP of the 1D. 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 3.72μm versus 11.56μm for the 1D). However, it should be noted that the M3 is much more recent (by 13 years and 4 months) than the 1D, 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 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 1D are 12.5 x 8.3 inches or 31.7 x 21.1 cm for good quality, 10 x 6.6 inches or 25.4 x 16.9 cm for very good quality, and 8.3 x 5.5 inches or 21.1 x 14.1 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-1D has a native sensitivity range from ISO 200 to ISO 1600, which can be extended to ISO 100-3200. 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.

In terms of underlying technology, the 1D is build around a CCD sensor, while the M3 uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

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"). 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 M3 indeed provides for movie recording, while the 1D does not. The highest resolution format that the M3 can use is 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the 1D 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 1D, the Canon M3, and comparable cameras.

One feature that is present on the 1D, but is missing on the M3 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The 1D writes its imaging data to Compact Flash cards, while the M3 uses SDXC cards.

Connectivity comparison

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-1D and Canon EOS M3 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, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 1D does not provide wifi capability.

Studio photographers will appreciate that the Canon 1D (unlike the M3) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 1D and the M3 have been discontinued, but can regularly be found used on ebay. The 1D was replaced by the Canon 1D Mark II, while the M3 was followed by the Canon M6. Further information on the features and operation of the 1D and M3 can be found, respectively, in the Canon 1D Manual (free pdf) or the online Canon M3 Manual.

Review summary

So how do things add up? Which of the two cameras – the Canon 1D or the Canon M3 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Canon EOS-1D:

• 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 (1/16000s vs 1/4000s) to freeze action.
• Faster burst: Shoots at higher frequency (8 vs 4.2 flaps/sec) to capture the decisive moment.
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• Longer lasting: Can take more shots (500 versus 250) on a single battery charge.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• 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 September 2001).

Arguments in favor of the Canon EOS M3:

• More detail: Has more megapixels (24 vs 4.1MP), which boosts linear resolution by 140%.
• Better jpgs: Has a more modern image processing engine (DIGIC 6 vs DIGIC).
• 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 2.0") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 120k dots).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• More compact: Is smaller (111x68mm vs 156x158mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 1219g or 77 percent) and is thus easier to take along.
• More legacy lens friendly: Can use many non-native lenses via adapters.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
• 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.
• More affordable: Was introduced into a lower priced category (90 percent cheaper at launch).
• More modern: Reflects 13 years and 4 months of technical progress since the 1D launch.

If the number of relative strengths (bullet points above) is taken as a guide, the M3 is the clear winner of the contest (17 : 9 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 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 1D and the Canon M3 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 remains incomplete and does no justice, for example, to the way the 1D or the M3 perform in practice. 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.

Expert reviews

This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
