Canon T6s vs Olympus E-30
The Canon EOS Rebel T6s (called Canon 760D in some regions) and the Olympus E-30 are two digital cameras that were revealed to the public, respectively, in February 2015 and November 2008. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (T6s) and a Four Thirds (E-30) sensor. The Canon has a resolution of 24 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 Rebel T6s 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 T6s 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 consecutive views from the front, the top, and the rear side 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 (15 percent) than the Canon T6s. Moreover, the E-30 is markedly heavier (24 percent) than the T6s. In this context, it is worth noting that neither the T6s nor the E-30 are weather-sealed.
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 (T6s) and the Four Thirds Lens Catalog (E-30).
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 T6s was launched at a markedly lower price (by 50 percent) than the E-30, 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 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon T6s features an APS-C sensor and the Olympus E-30 a Four Thirds sensor. The sensor area in the E-30 is 32 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 T6s has a native 3:2 aspect ratio, while the one in the E-30 offers a 4:3 aspect.
With 24MP, the T6s offers a higher resolution than the E-30 (12.2MP), but the T6s has smaller individual pixels (pixel pitch of 3.72μm versus 4.29μm for the E-30). However, the T6s is a much more recent model (by 6 years and 3 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 T6s implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T6s for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 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 T6s has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS Rebel T6s has a native sensitivity range from ISO 100 to ISO 12800, which can be extended to ISO 100-25600. 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 is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under review, the T6s provides substantially higher image quality than the E-30, with an overall score that is 15 points higher. This advantage is based on 1.3 bits higher color depth, 1.6 EV in additional dynamic range, and 0.8 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 T6s indeed provides movie recording capabilities, while the E-30 does not. The highest resolution format that the T6s can use is 1080/30p.
Beyond body and sensor, cameras can and do differ across a range of features. The T6s 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 viewfinders of both cameras offer the same magnification (0.51x), but the one in the E-30 has a wider field of view (98%) than the finder in the T6s (95%), so that a larger proportion of the captured image is visible. The following table reports on some other key feature differences and similarities of the Canon T6s, the Olympus E-30, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The T6s 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 T6s 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 T6s 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 Rebel T6s and Olympus E-30 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the T6s 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.
Both the T6s and the E-30 have been discontinued, but can regularly be found used on eBay. The T6s was replaced by the Canon 77D, while the E-30 does not have a direct successor. 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? Is the Canon T6s better than the Olympus E-30 or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Canon EOS Rebel T6s:
- More detail: Offers more megapixels (24 vs 12.2MP) with a 43% higher linear resolution.
- Better image quality: Scores substantially higher (15 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (1.3 bits more color depth).
- More dynamic range: Captures a larger spectrum of light and dark details (1.6 EV of extra DR).
- Better low-light sensitivity: Requires less light for good images (0.8 stops ISO advantage).
- Broader imaging potential: Can record not only still images but also 1080/30p movies.
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- 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 230k dots).
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- More compact: Is smaller (132x101mm vs 142x108mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 136g or 19 percent) and hence easier to carry around.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
- More affordable: Was introduced into a lower priced category (50 percent cheaper at launch).
- More modern: Reflects 6 years and 3 months of technical progress since the E-30 launch.
Arguments in favor of the Olympus E-30:
- More complete view: Has a viewfinder with a larger field of view (98% vs 95%).
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Longer lasting: Gets more shots (750 versus 440) out of a single battery charge.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- More heavily discounted: Has been around for much longer (launched in November 2008).
If the count of relative strengths (bullet points above) is taken as a measure, the T6s is the clear winner of the match-up (16 : 7 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 Canon T6s and the Olympus E-30 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 T6s and the E-30 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.
This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.
