Canon 100D vs Olympus E-400

The Canon EOS 100D (called Canon SL1 in some regions) and the Olympus E-400 are two digital cameras that were announced, respectively, in March 2013 and September 2006. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (100D) and a Four Thirds (E-400) 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 100D and the Olympus E-400? 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 100D and the Olympus E-400 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 100D can be obtained in two different colors (black, white), while the E-400 is only available in black.

Compare 100D versus E-400 top
Comparison 100D or E-400 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-400 is notably larger (11 percent) than the Canon 100D. Moreover, the E-400 is markedly heavier (7 percent) than the 100D. In this context, it is worth noting that neither the 100D nor the E-400 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 (100D) and the Four Thirds Lens Catalog (E-400).

Concerning battery life, the 100D gets 380 shots out of its LP-E12 battery, while the E-400 can take 500 images on a single charge of its BLS-1 power pack.

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

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

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 100D was launched at a somewhat lower price (by 21 percent) than the E-400, 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 100D features an APS-C sensor and the Olympus E-400 a Four Thirds sensor. The sensor area in the E-400 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 100D has a native 3:2 aspect ratio, while the one in the E-400 offers a 4:3 aspect.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.

Canon 100D and Olympus E-400 sensor measures

With 17.9MP, the 100D offers a higher resolution than the E-400 (10MP), but the 100D has smaller individual pixels (pixel pitch of 4.31μm versus 4.74μm for the E-400). However, the 100D is a much more recent model (by 6 years and 6 months) than the E-400, 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 100D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 100D 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-400 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 100D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS 100D 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-400 are ISO 100 to ISO 1600 (no boost).

100D versus E-400 MP

Many modern cameras cannot only take still pictures, but also record videos. The 100D indeed provides movie recording capabilities, while the E-400 does not. The highest resolution format that the 100D can use is 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The 100D and the E-400 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 100D has a higher magnification than the one of the E-400 (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 100D, the Olympus E-400, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The 100D has a touchscreen, while the E-400 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The 100D writes its imaging data to SDXC cards, while the E-400 uses Compact Flash or xD Picture cards. The E-400 features dual card slots, which can be very useful in case a memory card fails. In contrast, the 100D 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 100D and Olympus E-400 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the 100D and the E-400 have been discontinued, but can regularly be found used on eBay. The E-400 was replaced by the Olympus E-410, while the 100D was followed by the Canon 200D. 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.

Review summary

So what is the bottom line? Is there a clear favorite between the Canon 100D and the Olympus E-400? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Reasons to prefer the Canon EOS 100D:

  • More detail: Offers more megapixels (17.9 vs 10MP) with a 37% higher linear resolution.
  • Better image quality: Features a larger and more technologically advanced imaging sensor.
  • Richer colors: The sensor size advantage translates into images with better, more accurate colors.
  • More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
  • Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
  • 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 and 6 months of technical progress since the E-400 launch.

ilogo

Arguments in favor of the Olympus E-400:

  • 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 September 2006).

If the count of relative strengths (bullet points above) is taken as a measure, the 100D is the clear winner of the match-up (14 : 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.

100D 14:03 E-400

How about other alternatives? Do the specifications of the Canon 100D and the Olympus E-400 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 100D or the E-400 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

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.
