Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus E-450 and the Canon EOS 6D? 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 Olympus E-450 and the Canon 6D. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side 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 Canon 6D is notably larger (36 percent) than the Olympus E-450. Moreover, the 6D is substantially heavier (75 percent) than the E-450. It is noteworthy in this context that the 6D is splash and dust-proof, while the E-450 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 compare the optics available for the two cameras in the Four Thirds Lens Catalog (E-450) and the Canon EF Lens Catalog (6D).

Concerning battery life, the E-450 gets 500 shots out of its Olympus BLS-1 battery, while the 6D can take 1090 images on a single charge of its Canon LP-E6 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will obviously take relative prices into account. 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-450 was launched at a markedly lower price (by 76 percent) than the 6D, 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. 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Olympus E-450 features a Four Thirds sensor and the Canon 6D a full frame sensor. The sensor area in the 6D is 284 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.0. The sensor in the E-450 has a native 4:3 aspect ratio, while the one in the 6D offers a 3:2 aspect.

With 20MP, the 6D offers a higher resolution than the E-450 (10MP), but the 6D nevertheless has larger individual pixels (pixel pitch of 6.57μm versus 4.74μm for the E-450) due to its larger sensor. Moreover, the 6D is a much more recent model (by 3 years and 5 months) than the E-450, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Canon 6D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 6D for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Olympus E-450 are 18.2 x 13.7 inches or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inches or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inches or 30.9 x 23.2 cm for excellent quality prints.

The Olympus E-450 has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Canon EOS 6D are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-102400.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). Of the two cameras under consideration, the 6D offers substantially better image quality than the E-450 (overall score 26 points higher). The advantage is based on 2.3 bits higher color depth, 1.6 EV in additional dynamic range, and 2.2 stops in additional low light sensitivity. 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 6D indeed provides for movie recording, while the E-450 does not. The highest resolution format that the 6D can use is 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The E-450 and the 6D 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 6D offers a wider field of view (97%) than the one in the E-450 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the 6D has a higher magnification (0.71x vs 0.46x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Olympus E-450 and Canon 6D along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The E-450 has one, while the 6D does not. While the built-in flash of the E-450 is not very powerful, it can at times be useful as a fill-in light.

The E-450 writes its imaging data to Compact Flash or xD Picture cards, while the 6D uses SDXC cards. The E-450 features dual card slots, which can be very useful in case a memory card fails. In contrast, the 6D 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 Olympus E-450 and Canon EOS 6D and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 6D offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the E-450 does not provide wifi capability.

Travel and landscape photographers will find it useful that the 6D has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the E-450 and the 6D have been discontinued, but can regularly be found used on ebay. The 6D was replaced by the Canon 6D Mark II, while the E-450 does not have a direct successor. Further information on the features and operation of the E-450 and 6D can be found, respectively, in the Olympus E-450 Manual (free pdf) or the online Canon 6D Manual.

Review summary

So what is the bottom line? Is the Olympus E-450 better than the Canon 6D or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Olympus E-450:

• More compact: Is smaller (130x91mm vs 145x111mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 330g or 43 percent) and hence easier to carry around.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• 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 (76 percent cheaper at launch).
• More heavily discounted: Has been available for much longer (launched in March 2009).

Arguments in favor of the Canon EOS 6D:

• More detail: Has more megapixels (20 vs 10MP), which boosts linear resolution by 44%.
• Better image quality: Scores substantially higher (26 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (2.3 bits more color depth).
• More dynamic range: Captures a broader range of light and dark details (1.6 EV of extra DR).
• Better low-light sensitivity: Can shoot in dim conditions (2.2 stops ISO advantage).
• Broader imaging potential: Can capture not only stills but also 1080/30p video.
• More complete view: Has a viewfinder with a larger field of view (97% vs 95%).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.71x vs 0.46x).
• Easier setting verification: Features a control panel on top to check shooting parameters.
• Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 215k dots).
• Faster burst: Shoots at higher frequency (4.5 vs 3.5 flaps/sec) to capture the decisive moment.
• Longer lasting: Gets more shots (1090 versus 500) out of a single battery charge.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Easier geotagging: Features an internal GPS sensor to log localization data.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• More modern: Reflects 3 years and 5 months of technical progress since the E-450 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the 6D is the clear winner of the contest (17 : 6 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 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 Olympus E-450 and the Canon 6D 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 says little about, for example, the shooting experience and imaging performance of the E-450 and the 6D in practical situations. 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.

Expert reviews

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

A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
