Canon 1D vs Olympus E-M5

The Canon EOS-1D and the Olympus OM-D E-M5 are two digital cameras that were officially introduced, respectively, in September 2001 and February 2012. The 1D is a DSLR, while the E-M5 is a mirrorless interchangeable lens camera. The cameras are based on an APS-H (1D) and a Four Thirds (E-M5) sensor. The Canon has a resolution of 4.1 megapixel, whereas the Olympus provides 15.9 MP. 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 1D vs Olympus E-M5

The side-by-side display below illustrates the physical size and weight of the Canon 1D and the Olympus E-M5. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions 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 1D – 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 Olympus E-M5 is considerably smaller (56 percent) than the Canon 1D. Moreover, the E-M5 is substantially lighter (73 percent) than the 1D. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (1D) and the Micro Four Thirds Lens Catalog (E-M5). Mirrorless cameras, such as the E-M5, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.

Concerning battery life, the 1D gets 500 shots out of its NP-E3 battery, while the E-M5 can take 360 images on a single charge of its BLN-1 power pack. As can be seen in the images above, the 1D has a battery grip build in. This facilitates image-taking in portrait orientation and gives it additional battery power. In order to provide similar functionality for the E-M5, Olympus provides the HLD-6 vertical grip as an optional accessory (see here on eBay).

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 E-M5 was launched at a markedly lower price (by 80 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.

Sensor comparison: Canon 1D vs Olympus E-M5

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. 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.

Of the two cameras under consideration, the Canon 1D features an APS-H sensor and the Olympus E-M5 a Four Thirds sensor. The sensor area in the E-M5 is 59 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 and 2.0. The sensor in the 1D has a native 3:2 aspect ratio, while the one in the E-M5 offers a 4:3 aspect.

Despite having a smaller sensor, the E-M5 offers a higher resolution of 15.9 megapixel, compared with 4.1 MP of the 1D. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.76μm versus 11.56μm for the 1D). However, it should be noted that the E-M5 is much more recent (by 10 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.

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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The E-M5 indeed provides for movie recording, while the 1D does not. The highest resolution format that the E-M5 can use is 1080/60i.

Feature comparison: Canon 1D vs Olympus E-M5

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the E-M5 has an electronic viewfinder (1440k dots), while the 1D has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The adjacent table lists some of the other core features of the Canon 1D and Olympus E-M5 along with similar information for a selection of comparators. The full specs-sheets can be found in the camera manual or in the dpreview camera hub.

One feature that is present on the 1D, but is missing on the E-M5 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 E-M5 uses SDXC cards. The 1D features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-M5 only has one slot.

I-O connection comparison: Canon 1D vs Olympus E-M5

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 Olympus OM-D E-M5 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the 1D and the E-M5 have been discontinued, but can regularly be found used on eBay. The 1D was replaced by the Canon 1D Mark II, while the E-M5 was followed by the Olympus E-M5 II.

Review summary: Canon 1D vs Olympus E-M5

So what conclusions can be drawn? Is there a clear favorite between the Canon 1D and the Olympus E-M5? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Canon EOS-1D:

• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• Easier setting verification: Features an LCD display on top to control shooting parameters.
• Faster shutter: Has higher mechanical shutter speed (16000/sec vs 4000/sec) to freeze action.
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• Longer lasting: Can take more shots (500 versus 360) on a single battery charge.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More heavily discounted: Has been available for much longer (launched in September 2001).

Advantages of the Olympus OM-D E-M5:

• More detail: Has more megapixels (15.9 vs 4.1MP), which boosts linear resolution by 92%.
• Broader imaging potential: Can capture not only stills but also 1080/60i video.
• More framing info: Has an electronic viewfinder that displays shooting data.
• 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 (610k 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.
• Faster burst: Shoots at higher frequency (9 vs 8 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (122x89mm vs 156x158mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 1160g or 73 percent) and is thus easier to take along.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• More legacy lens friendly: Can use many non-native lenses via adapters.
• More affordable: Was introduced into a lower priced category (80 percent cheaper at launch).
• More modern: Reflects 10 years and 4 months of technical progress since the 1D launch.

If the count of individual advantages (bullet points above) is taken as a guide, the E-M5 is the clear winner of the contest (14 : 7 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 technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the 1D or the E-M5 handle or perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
