Canon SL1 vs Olympus E-410

The Canon EOS Rebel SL1 (called Canon 100D in some regions) and the Olympus E-410 are two digital cameras that were announced, respectively, in March 2013 and March 2007. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (SL1) and a Four Thirds (E-410) sensor. The Canon has a resolution of 17.9 megapixels, whereas the Olympus provides 10 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 SL1 and the Olympus E-410? 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 Canon SL1 and the Olympus E-410 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter.

The SL1 can be obtained in two different colors (black, white), while the E-410 is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-410 is notably larger (11 percent) than the Canon SL1. Moreover, the E-410 is markedly heavier (7 percent) than the SL1. In this context, it is worth noting that neither the SL1 nor the E-410 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 (SL1) and the Four Thirds Lens Catalog (E-410).

Concerning battery life, the SL1 gets 380 shots out of its Canon LP-E12 battery, while the E-410 can take 500 images on a single charge of its Olympus BLS-1 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

The price is, of course, an important factor in any camera decision. 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 SL1 was launched at a somewhat lower price (by 21 percent) than the E-410, which makes it more attractive for photographers on a tight budget. 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 sensor inside a digital camera is one of the key determinants 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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 Canon SL1 features an APS-C sensor and the Olympus E-410 a Four Thirds sensor. The sensor area in the E-410 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 SL1 has a native 3:2 aspect ratio, while the one in the E-410 offers a 4:3 aspect.

With 17.9MP, the SL1 offers a higher resolution than the E-410 (10MP), but the SL1 has smaller individual pixels (pixel pitch of 4.31μm versus 4.74μm for the E-410). However, the SL1 is a much more recent model (by 6 years) than the E-410, 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 SL1 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SL1 for good quality output (200 dots per inch) amounts to 25.9 x 17.3 inches or 65.8 x 43.9 cm, for very good quality (250 dpi) 20.7 x 13.8 inches or 52.7 x 35.1 cm, and for excellent quality (300 dpi) 17.3 x 11.5 inches or 43.9 x 29.3 cm. The corresponding values for the Olympus E-410 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 SL1 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS Rebel SL1 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-410 are ISO 100 to ISO 1600 (no boost).

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 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 SL1 provides substantially higher image quality than the E-410, with an overall score that is 12 points higher. This advantage is based on 0.7 bits higher color depth, 1.3 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 SL1 indeed provides movie recording capabilities, while the E-410 does not. The highest resolution format that the SL1 can use is 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The SL1 and the E-410 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 field of view (95%), but the viewfinder of the SL1 has a higher magnification than the one of the E-410 (0.54x vs 0.46x), 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 SL1, the Olympus E-410, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The SL1 has a touchscreen, while the E-410 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The SL1 writes its imaging data to SDXC cards, while the E-410 uses Compact Flash or xD Picture cards. The E-410 features dual card slots, which can be very useful in case a memory card fails. In contrast, the SL1 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 Canon EOS Rebel SL1 and Olympus E-410 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the SL1 and the E-410 have been discontinued, but can regularly be found used on ebay. The E-410 was replaced by the Olympus E-420, while the SL1 was followed by the Canon SL2. Further information on the features and operation of the SL1 and E-410 can be found, respectively, in the Canon SL1 Manual (free pdf) or the online Olympus E-410 Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Canon SL1 and the Olympus E-410? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Canon EOS Rebel SL1:

• More detail: Offers more megapixels (17.9 vs 10MP) with a 37% higher linear resolution.
• Better image quality: Scores substantially higher (12 points) in the DXO overall assessment.
• More dynamic range: Captures a larger spectrum of light and dark details (1.3 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 viewfinder image: Features a viewfinder with a higher magnification (0.54x vs 0.46x).
• 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 215k dots).
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• Faster burst: Shoots at higher frequency (4.9 vs 3 flaps/sec) to capture the decisive moment.
• More affordable: Was introduced into a lower priced segment (21 percent cheaper at launch).
• More modern: Reflects 6 years of technical progress since the E-410 launch.

Arguments in favor of the Olympus E-410:

• Longer lasting: Gets more shots (500 versus 380) out of a single battery charge.
• 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 March 2007).

If the count of relative strengths (bullet points above) is taken as a measure, the SL1 is the clear winner of the match-up (13 : 3 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 SL1 and the Olympus E-410 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 remains incomplete and does no justice, for example, to the way the SL1 or the E-410 perform in practice. 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 why hands-on reviews by experts 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], 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 review scores listed above should be treated with care, though. The assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
