Canon R vs Olympus E-30
The Canon EOS R and the Olympus E-30 are two digital cameras that were announced, respectively, in September 2018 and November 2008. The Canon R is a mirrorless interchangeable lens camera, while the E-30 is a DSLR. The cameras are based on a full frame (Canon R) and a Four Thirds (E-30) sensor. The Canon has a resolution of 30.1 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 R 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 R 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 measures 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 larger (13 percent) than the Canon R. Moreover, the E-30 is markedly heavier (6 percent) than the Canon R. It is worth mentioning in this context that the Canon R 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.
Concerning battery life, the Canon R gets 370 shots out of its LP-E6N battery, while the E-30 can take 750 images on a single charge of its BLM-1 power pack. The power pack in the Canon R can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

The price is, of course, an important factor in any camera decision. 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-30 was launched at a markedly lower price (by 43 percent) than the Canon R, 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.
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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Canon R features a full frame sensor and the Olympus E-30 a Four Thirds sensor. The sensor area in the E-30 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 Canon R has a native 3:2 aspect ratio, while the one in the E-30 offers a 4:3 aspect.
With 30.1MP, the Canon R offers a higher resolution than the E-30 (12.2MP), but the Canon R nevertheless has larger individual pixels (pixel pitch of 5.36μm versus 4.29μm for the E-30) due to its larger sensor. Moreover, the Canon R is a much more recent model (by 9 years and 10 months) than the E-30, 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 R implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the Canon R for good quality output (200 dots per inch) amounts to 33.6 x 22.4 inches or 85.3 x 56.9 cm, for very good quality (250 dpi) 26.9 x 17.9 inches or 68.3 x 45.5 cm, and for excellent quality (300 dpi) 22.4 x 14.9 inches or 56.9 x 37.9 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 Canon R has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS R has a native sensitivity range from ISO 100 to ISO 40000, which can be extended to ISO 50-102400. 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 Canon R provides substantially higher image quality than the E-30, with an overall score that is 34 points higher. This advantage is based on 3.2 bits higher color depth, 3.1 EV in additional dynamic range, and 2.4 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 are not only capable of taking still images, but also of capturing video footage. The Canon R indeed provides movie recording capabilities, while the E-30 does not. The highest resolution format that the Canon R can use is 4K/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the Canon R has an electronic viewfinder (3690k dots), while the E-30 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinder in the Canon R 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 Canon R has a higher magnification (0.76x vs 0.51x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Canon R, the Olympus E-30, and comparable cameras.

|17.||Sony A7 III||2359||n||3.0||922||tilting||Y||1/8000s||10.0||n||Y|
One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The Canon R has a touchscreen, while the E-30 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.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 reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the Canon R is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The Canon R writes its imaging data to SDXC cards, while the E-30 uses Compact Flash or xD Picture cards. The E-30 features dual card slots, which can be very useful in case a memory card fails. In contrast, the Canon R only has one slot.
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 R and Olympus E-30 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

|17.||Sony A7 III||Y||stereo||mono||Y||Y||micro||3.1||Y||Y||Y|
It is notable that the Canon R offers wifi support, while the E-30 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
The Canon R 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 conclusions can be drawn? Which of the two cameras – the Canon R 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.

If the count of relative strengths (bullet points above) is taken as a measure, the Canon R is the clear winner of the match-up (23 : 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 R and the Olympus E-30 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR Camera listings 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 remains incomplete and does no justice, for example, to the way the Canon R or the E-30 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 expert reviews 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], 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 assessments were made in relation to similar cameras of the same technological generation. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
