Olympus E-3 vs Canon 70D
The Olympus E-3 and the Canon EOS 70D are two digital cameras that were revealed to the public, respectively, in October 2007 and July 2013. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a Four Thirds (E-3) and an APS-C (70D) sensor. The Olympus has a resolution of 10 megapixels, whereas the Canon provides 20 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 Olympus E-3 and the Canon EOS 70D? 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 physical size and weight of the Olympus E-3 and the Canon 70D 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 70D is notably smaller (12 percent) than the Olympus E-3. Moreover, the 70D is markedly lighter (14 percent) than the E-3. 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 Four Thirds Lens Catalog (E-3) and the Canon EF Lens Catalog (70D).
Concerning battery life, the E-3 gets 750 shots out of its Olympus BLM-1 battery, while the 70D can take 920 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. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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 70D was launched at a markedly lower price (by 29 percent) than the E-3, 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.
Sensor comparison
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 more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Olympus E-3 features a Four Thirds sensor and the Canon 70D an APS-C sensor. The sensor area in the 70D is 50 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.6. The sensor in the E-3 has a native 4:3 aspect ratio, while the one in the 70D offers a 3:2 aspect.
With 20MP, the 70D offers a higher resolution than the E-3 (10MP), but the 70D has smaller individual pixels (pixel pitch of 4.11μm versus 4.74μm for the E-3). Yet, the 70D is a much more recent model (by 5 years and 8 months) than the E-3, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Canon 70D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 70D 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-3 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 70D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Olympus E-3 has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Canon EOS 70D are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 100-25600.
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.
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. Of the two cameras under consideration, the 70D offers substantially better image quality than the E-3 (overall score 12 points higher). The advantage is based on 0.9 bits higher color depth, 1.1 EV in additional dynamic range, and 0.7 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras cannot only take still pictures, but also record videos. The 70D indeed provides for movie recording, while the E-3 does not. The highest resolution format that the 70D can use is 1080/30p.
Feature comparison
Apart from body and sensor, cameras can and do differ across a variety of features. The E-3 and the 70D 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-3 offers a wider field of view (100%) than the one in the 70D (98%), so that a larger proportion of the captured image is visible in the finder. On the other hand, the viewfinder of the 70D has a higher magnification (0.59x vs 0.58x), 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-3 and Canon 70D along with similar information for a selection of comparators.

One feature that differentiates the E-3 and the 70D is in-body image stabilization (IBIS). The E-3 reduces the risk of handshake-induced blur with all attached lenses, while the 70D offers no blur reduction with lenses that themselves do not provide optical image stabilization.
Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.The E-3 writes its imaging data to Compact Flash or xD Picture cards, while the 70D uses SDXC cards. The E-3 features dual card slots, which can be very useful in case a memory card fails. In contrast, the 70D 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-3 and Canon EOS 70D and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 70D offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the E-3 does not provide wifi capability.
Studio photographers will appreciate that the Olympus E-3 (unlike the 70D) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the E-3 and the 70D have been discontinued, but can regularly be found used on ebay. The E-3 was replaced by the Olympus E-5, while the 70D was followed by the Canon 80D. Further information on the features and operation of the E-3 and 70D can be found, respectively, in the Olympus E-3 Manual (free pdf) or the online Canon 70D Manual.
Review summary
So what conclusions can be drawn? Is there a clear favorite between the Olympus E-3 and the Canon 70D? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Olympus E-3:
- More complete view: Has a viewfinder with a larger field of view (100% vs 98%).
- Sharper images: Has hand-shake reducing image stabilization built-in.
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- 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 October 2007).
Advantages of the Canon EOS 70D:
- More detail: Has more megapixels (20 vs 10MP), which boosts linear resolution by 44%.
- Better image quality: Scores substantially higher (12 points) in the DXO overall evaluation.
- More dynamic range: Captures a broader range of light and dark details (1.1 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (0.7 stops ISO advantage).
- Broader imaging potential: Can capture not only stills but also 1080/30p video.
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.59x vs 0.58x).
- Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- Faster burst: Shoots at higher frequency (7 vs 5 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (139x104mm vs 142x116mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 121g or 14 percent) and is thus easier to take along.
- Longer lasting: Gets more shots (920 versus 750) out of a single battery charge.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- More affordable: Was introduced into a lower priced category (29 percent cheaper at launch).
- More modern: Reflects 5 years and 8 months of technical progress since the E-3 launch.
If the number of relative strengths (bullet points above) is taken as a guide, the 70D is the clear winner of the contest (17 : 5 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. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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-3 and the Canon 70D 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the E-3 and the 70D in practical situations. 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 where reviews by experts come in. 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.

Care should be taken when interpreting the review scores above, 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 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.
