Canon 1Ds versus Olympus E-PL9

The Canon EOS-1Ds and the Olympus PEN E-PL9 are two digital cameras that were revealed to the public, respectively, in September 2002 and February 2018. The 1Ds is a DSLR, while the E-PL9 is a mirrorless interchangeable lens camera. The cameras are based on a full frame (1Ds) and a Four Thirds (E-PL9) sensor. The Canon has a resolution of 11 megapixel, whereas the Olympus provides 15.9 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon 1Ds vs Olympus E-PL9

The physical size and weight of the Canon 1Ds and the Olympus E-PL9 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter. You can also toggle the display to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the 1Ds – 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-PL9 is considerably smaller (68 percent) than the Canon 1Ds. Moreover, the E-PL9 is substantially lighter (70 percent) than the 1Ds. It is worth mentioning in this context that the 1Ds is splash and dust resistant, while the E-PL9 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can find an overview of optics for the two cameras in the Canon EF Lens Catalog (1Ds) and the Micro Four Thirds Lens Catalog (E-PL9). Mirrorless cameras, such as the E-PL9, 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 1Ds gets 600 shots out of its NP-E3 battery, while the E-PL9 can take 350 images on a single charge of its BLS-50 power pack. As can be seen in the images above, the 1Ds has a battery grip build in. This facilitates image-taking in portrait orientation and gives it additional battery power.

The camera’s price is obviously a critical decision-making factor. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The E-PL9 was launched at a markedly lower price (by 94 percent) than the 1Ds, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison: Canon 1Ds vs Olympus E-PL9

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 1Ds features a full frame sensor and the Olympus E-PL9 a Four Thirds sensor. The sensor area in the E-PL9 is 74 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.0. The sensor in the 1Ds has a native 3:2 aspect ratio, while the one in the E-PL9 offers a 4:3 aspect.

Despite having a smaller sensor, the E-PL9 offers a higher resolution of 15.9 megapixel, compared with 11 MP of the 1Ds. 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 8.83μm for the 1Ds). However, it should be noted that the E-PL9 is much more recent (by 15 years and 4 months) than the 1Ds, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). 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 E-PL9 indeed provides for movie recording, while the 1Ds does not. The highest resolution format that the E-PL9 can use is 4K/30p.

Feature comparison: Canon 1Ds vs Olympus E-PL9

Beyond body and sensor, cameras can and do differ across a range of features. For example, the 1Ds has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the E-PL9 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Canon 1Ds and Olympus E-PL9 in connection with corresponding information for a sample of similar cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

One feature that is present on the 1Ds, but is missing on the E-PL9 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 reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the E-PL9 features an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (rolling shutter) or shooting under artificial light sources (flickering).

The 1Ds writes its imaging data to Compact Flash cards, while the E-PL9 uses SDXC cards. The 1Ds features dual card slots, which can be very useful in case a memory card fails. In contrast, the E-PL9 only has one slot.

The E-PL9 is a recent model that features in the current product line-up of Olympus. In contrast, the 1Ds has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 1Ds was succeeded by the Canon 1Ds Mark II.

Review summary: Canon 1Ds vs Olympus E-PL9

So how do things add up? Is the Canon 1Ds better than the Olympus E-PL9 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Canon EOS-1Ds:

• Easier framing: Has an optical viewfinder for image framing and settings control.
• Easier setting verification: Features an LCD display on top to control shooting parameters.
• Faster shutter: Has higher mechanical shutter speed (8000/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 (600 versus 350) on a single battery charge.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• 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 2002).

Advantages of the Olympus PEN E-PL9:

• More detail: Has more megapixels (15.9 vs 11MP), which boosts linear resolution by 18%.
• Broader imaging potential: Can capture not only stills but also 4K/30p video.
• 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.
• Faster burst: Shoots at higher frequency (8.6 vs 3 flaps/sec) to capture the decisive moment.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• More compact: Is smaller (117x68mm vs 156x157.6mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 885g or 70 percent) and is thus easier to take along.
• Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
• 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 build in for automatic backup or image transfer to the web.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More affordable: Was introduced into a lower priced category (94 percent cheaper at launch).
• More modern: Reflects 15 years and 4 months of technical progress since the 1Ds launch.

If the count of individual advantages (bullet points above) is taken as a guide, the E-PL9 is the clear winner of the contest (17 : 8 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.

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 1Ds or the E-PL9 handle or perform in practice. 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 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, please note that some of the review sites have changed their methodology and reporting over time.
