Canon 5D vs Olympus E-1

The Canon EOS 5D and the Olympus E-1 are two professional cameras that were officially introduced, respectively, in August 2005 and June 2003. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (5D) and a Four Thirds (E-1) sensor. The Canon has a resolution of 12.7 megapixels, whereas the Olympus provides 4.9 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 5D and the Olympus E-1? 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 5D and the Olympus E-1. 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 the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-1 is notably smaller (15 percent) than the Canon 5D. Moreover, the E-1 is markedly lighter (18 percent) than the 5D. 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 (5D) and the Four Thirds Lens Catalog (E-1).

Concerning battery life, the 5D gets 400 shots out of its Canon BP-511A battery, while the E-1 can take 750 images on a single charge of its Olympus BLM-1 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

Any camera decision will obviously take relative prices into account. 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-1 was launched at a markedly lower price (by 48 percent) than the 5D, 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

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. 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 5D features a full frame sensor and the Olympus E-1 a Four Thirds sensor. The sensor area in the E-1 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 5D has a native 3:2 aspect ratio, while the one in the E-1 offers a 4:3 aspect.

With 12.7MP, the 5D offers a higher resolution than the E-1 (4.9MP), but the 5D nevertheless has larger individual pixels (pixel pitch of 8.25μm versus 6.78μm for the E-1) due to its larger sensor. Moreover, the 5D is a much more recent model (by 2 years and 1 month) than the E-1, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The resolution advantage of the Canon 5D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 5D for good quality output (200 dots per inch) amounts to 21.8 x 14.6 inches or 55.5 x 37 cm, for very good quality (250 dpi) 17.5 x 11.6 inches or 44.4 x 29.6 cm, and for excellent quality (300 dpi) 14.6 x 9.7 inches or 37 x 24.7 cm. The corresponding values for the Olympus E-1 are 12.8 x 9.6 inches or 32.5 x 24.4 cm for good quality, 10.2 x 7.7 inches or 26 x 19.5 cm for very good quality, and 8.5 x 6.4 inches or 21.7 x 16.3 cm for excellent quality prints.

The Canon EOS 5D has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 50-3200. The corresponding ISO settings for the Olympus E-1 are ISO 100 to ISO 800, with the possibility to increase the ISO range to 100-3200.

In terms of underlying technology, the 5D is build around a CMOS sensor, while the E-1 uses a CCD 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 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. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The 5D and the E-1 are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The viewfinder in the E-1 offers a wider field of view (100%) than the one in the 5D (96%), so that a larger proportion of the captured image is visible in the finder. On the other hand, the viewfinder of the 5D has a higher magnification (0.71x vs 0.48x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Canon 5D and Olympus E-1 in connection with corresponding information for a sample of similar cameras.

The 5D writes its imaging data to Compact Flash cards, while the E-1 uses Compact Flash or xD Picture cards. The E-1 features dual card slots, which can be very useful in case a memory card fails. In contrast, the 5D only has one slot.

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 5D and Olympus E-1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.

Both the 5D and the E-1 have been discontinued, but can regularly be found used on ebay. The E-1 was replaced by the Olympus E-3, while the 5D was followed by the Canon 5D Mark II. Further information on the features and operation of the 5D and E-1 can be found, respectively, in the Canon 5D Manual (free pdf) or the online Olympus E-1 Manual.

Review summary

So what conclusions can be drawn? Is the Canon 5D better than the Olympus E-1 or vice versa? The listing below highlights the relative strengths of the two models.

Advantages of the Canon EOS 5D:

• More detail: Offers more megapixels (12.7 vs 4.9MP) with a 64% higher linear resolution.
• Better image quality: Features a larger and more technologically advanced imaging sensor.
• Richer colors: The sensor size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.71x vs 0.48x).
• Larger screen: Has a bigger rear LCD (2.5" vs 1.8") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (230k vs 134k dots).
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• More modern: Reflects 2 years and 1 month of technical progress since the E-1 launch.

Reasons to prefer the Olympus E-1:

• More complete view: Has a viewfinder with a larger field of view (100% vs 96%).
• More compact: Is smaller (141x104mm vs 152x113mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 157g or 18 percent) and is thus easier to take along.
• Longer lasting: Gets more shots (750 versus 400) out of a single battery charge.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More affordable: Was introduced into a lower priced category (48 percent cheaper at launch).
• More heavily discounted: Has been around for much longer (launched in June 2003).

If the number of relative strengths (bullet points above) is taken as a guide, the 5D emerges as the winner of the contest (10 : 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. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro 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 5D and the Olympus E-1 place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing whether the two cameras rank among the cream of the crop.

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 5D or the E-1 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.

Expert reviews

This is why hands-on reviews by experts are important. 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.

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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
