Canon 1Ds Mark III versus Olympus E-PL8

The Canon EOS-1Ds Mark III and the Olympus PEN E-PL8 are two digital cameras that were revealed to the public, respectively, in August 2007 and September 2016. The 1Ds Mark III is a DSLR, while the E-PL8 is a mirrorless interchangeable lens camera. The cameras are based on a full frame (1Ds Mark III) and a Four Thirds (E-PL8) sensor. The Canon has a resolution of 21 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 Mark III vs Olympus E-PL8

The physical size and weight of the Canon 1Ds Mark III and the Olympus E-PL8 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 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 Mark III – represents the basis or 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-PL8 is considerably smaller (68 percent) than the Canon 1Ds Mark III. Moreover, the E-PL8 is substantially lighter (74 percent) than the 1Ds Mark III. It is worth mentioning in this context that the 1Ds Mark III is splash and dust resistant, while the E-PL8 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 Mark III) and the Micro Four Thirds Lens Catalog (E-PL8). Mirrorless cameras, such as the E-PL8, 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 Mark III gets 1800 shots out of its LP-E4 battery, while the E-PL8 can take 350 images on a single charge of its BLS-50 power pack.

Any camera purchase will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The E-PL8 was launched at a markedly lower price (by 93 percent) than the 1Ds Mark III, 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 1Ds Mark III vs Olympus E-PL8

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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Canon 1Ds Mark III features a full frame sensor and the Olympus E-PL8 a Four Thirds sensor. The sensor area in the E-PL8 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 Mark III has a native 3:2 aspect ratio, while the one in the E-PL8 offers a 4:3 aspect.

Canon 1Ds Mark III and Olympus E-PL8 sensor measures

With 21MP, the 1Ds Mark III offers a higher resolution than the E-PL8 (15.9MP), but the 1Ds Mark III nevertheless has larger individual pixels (pixel pitch of 6.41μm versus 3.76μm for the E-PL8) due to its larger sensor. However, the E-PL8 is a somewhat more recent model (by 9 years and 1 month) than the 1Ds Mark III, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • More heavily discounted: Has been available for much longer (launched in August 2007).

ilogo

Advantages of the Olympus PEN E-PL8:

  • Broader imaging potential: Can capture not only stills but also 1080/30p video.
  • More detailed LCD: Has a higher resolution rear screen (1037k vs 230k 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 vs 5 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (115x67mm vs 150x160mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 1028g or 74 percent) and is thus easier to take along.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More affordable: Was introduced into a lower priced category (93 percent cheaper at launch).
  • More modern: Reflects 9 years and 1 month of technical progress since the 1Ds Mark III launch.

If the count of individual advantages (bullet points above) is taken as a guide, the E-PL8 is the clear winner of the contest (11 : 7 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.

1Ds Mark III 07:11 E-PL8

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 Mark III or the E-PL8 handle or 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. This is why hands-on reviews by experts are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The above review scores should be interpreted with care, though. The ratings are only valid when refering 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
