Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 100D and the Sony Alpha SLT-A58? 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 Sony A58 are illustrated 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.

The 100D can be obtained in two different colors (black, white), while the A58 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 Sony A58 is notably larger (15 percent) than the Canon 100D. Moreover, the A58 is markedly heavier (21 percent) than the 100D. In this context, it is worth noting that neither the 100D nor the A58 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. 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 100D gets 380 shots out of its Canon LP-E12 battery, while the A58 can take 690 images on a single charge of its Sony NP-FM500H power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 100D was somewhat cheaper (by 8 percent) than the A58 at launch, but both cameras fall into the same price category. 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.

Sensor comparison

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the A58 is 11 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (100D) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 19.8MP, the A58 offers a higher resolution than the 100D (17.9MP), but the A58 nevertheless has the same individual pixel size (pixel pitch of 4.31μm) as the 100D due to its larger sensor. It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation.

The resolution advantage of the Sony A58 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A58 for good quality output (200 dots per inch) amounts to 27.3 x 18.2 inches or 69.3 x 46.1 cm, for very good quality (250 dpi) 21.8 x 14.5 inches or 55.4 x 36.9 cm, and for excellent quality (300 dpi) 18.2 x 12.1 inches or 46.2 x 30.8 cm. The corresponding values for the Canon 100D are 25.9 x 17.3 inches or 65.8 x 43.9 cm for good quality, 20.7 x 13.8 inches or 52.7 x 35.1 cm for very good quality, and 17.3 x 11.5 inches or 43.9 x 29.3 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 Sony Alpha SLT-A58 are ISO 100 to ISO 16000, with the possibility to increase the ISO range to 100-25600.

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.

For many cameras, data on sensor performance has been reported by DXO Mark. 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 consideration, the A58 offers substantially better image quality than the 100D (overall score 11 points higher). The advantage is based on 1.5 bits higher color depth, 1.2 EV in additional dynamic range, and 0.2 stops of reduced 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. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the A58 provides a faster frame rate than the 100D. It can shoot movie footage at 1080/60i, while the Canon is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A58 has an electronic viewfinder (1440k dots), while the 100D 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 A58 offers a wider field of view (100%) than the one in the 100D (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the A58 has a higher magnification (0.57x vs 0.54x), 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 Sony A58, 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 A58 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 A58 uses SDXC or Memory Stick PRO Duo cards. The 100D supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the A58 cannot take advantage of Ultra High Speed SD cards.

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 Sony Alpha SLT-A58 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the 100D and the A58 have been discontinued, but can regularly be found used on ebay. The A58 was replaced by the Sony A68, while the 100D was followed by the Canon 200D. Further information on the features and operation of the 100D and A58 can be found, respectively, in the Canon 100D Manual (free pdf) or the online Sony A58 Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Canon 100D or the Sony A58 – 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.

Arguments in favor of the Canon EOS 100D:

• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• 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 460k dots).
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• More compact: Is smaller (117x91mm vs 129x95mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 85g or 17 percent) and hence easier to carry around.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.

Reasons to prefer the Sony Alpha SLT-A58:

• More detail: Has more megapixels (19.8 vs 17.9MP), which boosts linear resolution by 5%.
• Better image quality: Scores substantially higher (11 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (1.5 bits more color depth).
• More dynamic range: Captures a broader range of light and dark details (1.2 EV of extra DR).
• Better video: Provides higher movie framerates (1080/60i versus 1080/30p).
• More framing info: Has an electronic viewfinder that displays shooting data.
• More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.57x vs 0.54x).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Longer lasting: Gets more shots (690 versus 380) out of a single battery charge.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.

If the count of relative strengths (bullet points above) is taken as a measure, the A58 emerges as the winner of the match-up (11 : 8 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 100D and the Sony A58 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 remains incomplete and does no justice, for example, to the way the 100D or the A58 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.

Expert reviews

This is where reviews by experts come in. 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 above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
