Canon 7D II vs Olympus E-30
The Canon EOS 7D Mark II and the Olympus E-30 are two enthusiast cameras that were revealed to the public, respectively, in September 2014 and November 2008. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (7D Mark II) and a Four Thirds (E-30) sensor. The Canon has a resolution of 20 megapixels, whereas the Olympus provides 12.2 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 7D Mark II and the Olympus E-30? 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.
An illustration of the physical size and weight of the Canon 7D II and the Olympus E-30 is provided 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 width, height and depth 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-30 is notably smaller (8 percent) than the Canon 7D II. Moreover, the E-30 is markedly lighter (23 percent) than the 7D Mark II. It is worth mentioning in this context that the 7D Mark II is splash and dust resistant, while the E-30 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 Canon EF Lens Catalog (7D Mark II) and the Four Thirds Lens Catalog (E-30).
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-30 was launched at a markedly lower price (by 28 percent) than the 7D Mark II, 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.
The size of the imaging sensor is a crucial determinant of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon 7D II features an APS-C sensor and the Olympus E-30 a Four Thirds sensor. The sensor area in the E-30 is 33 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 2.0. The sensor in the 7D Mark II has a native 3:2 aspect ratio, while the one in the E-30 offers a 4:3 aspect.
With 20MP, the 7D Mark II offers a higher resolution than the E-30 (12.2MP), but the 7D Mark II has smaller individual pixels (pixel pitch of 4.10μm versus 4.29μm for the E-30). However, the 7D Mark II is a much more recent model (by 5 years and 10 months) than the E-30, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.
The resolution advantage of the Canon 7D II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 7D Mark II 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-30 are 20.2 x 15.1 inches or 51.2 x 38.4 cm for good quality, 16.1 x 12.1 inches or 41 x 30.7 cm for very good quality, and 13.4 x 10.1 inches or 34.1 x 25.6 cm for excellent quality prints.
The 7D Mark II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS 7D Mark II has a native sensitivity range from ISO 100 to ISO 16000, which can be extended to ISO 100-51200. The corresponding ISO settings for the Olympus E-30 are ISO 100 to ISO 3200 (no boost).
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 review, the 7D Mark II provides substantially higher image quality than the E-30, with an overall score that is 15 points higher. This advantage is based on 1.1 bits higher color depth, 1.4 EV in additional dynamic range, and 1 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. The 7D Mark II indeed provides movie recording capabilities, while the E-30 does not. The highest resolution format that the 7D Mark II can use is 1080/60p.
Beyond body and sensor, cameras can and do differ across a range of features. The 7D Mark II and the E-30 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 7D Mark II offers a wider field of view (100%) than the one in the E-30 (98%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the 7D Mark II has a higher magnification (0.63x vs 0.51x), 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 Canon 7D II and Olympus E-30 along with similar information for a selection of comparators.

One feature that differentiates the E-30 and the 7D Mark II is in-body image stabilization (IBIS). The E-30 reduces the risk of handshake-induced blur with all attached lenses, while the 7D Mark II offers no blur reduction with lenses that themselves do not provide optical image stabilization.The E-30 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the 7D Mark II does not have a selfie-screen.
The Canon 7D II has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
The 7D Mark II writes its imaging data to Compact Flash or SDXC cards, while the E-30 uses Compact Flash or xD Picture cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails.
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 7D Mark II and Olympus E-30 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon 7D II (unlike the E-30) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Travel and landscape photographers will find it useful that the 7D Mark II has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.
The 7D Mark II is a recent model that features in the current product line-up of Canon. In contrast, the E-30 has been discontinued (but can be found pre-owned on eBay). There has not been a direct replacement model for the E-30 from Olympus. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Olympus websites.
So what is the bottom line? Which of the two cameras – the Canon 7D II or the Olympus E-30 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

- More heavily discounted: Has been around for much longer (launched in November 2008).
If the count of individual advantages (bullet points above) is taken as a guide, the 7D Mark II is the clear winner of the match-up (18 : 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. 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.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 7D Mark II or the E-30. 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 expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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 review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
