Canon SL1 vs Sony A3000

The Canon EOS Rebel SL1 (called Canon 100D in some regions) and the Sony Alpha A3000 are two digital cameras that were revealed to the public, respectively, in March 2013 and August 2013. The SL1 is a DSLR, while the A3000 is a mirrorless interchangeable lens camera. Both cameras are equipped with an APS-C sensor. The Canon has a resolution of 17.9 megapixels, whereas the Sony provides 19.8 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 Sony Alpha A3000? 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 Sony A3000 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 A3000 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 A3000 is notably larger (9 percent) than the Canon SL1. Moreover, the A3000 is slightly heavier (1 percent) than the SL1. In this context, it is worth noting that neither the SL1 nor the A3000 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. Both cameras have similarly sized sensors, but DSLRs have a larger flange-to-focal plane distance than mirrorless cameras, which imposes contraints on the optical engineering process and generally leads to bigger and heavier lenses. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (SL1) and the Sony E-Mount Lens Catalog (A3000). Mirrorless cameras, such as the A3000, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.

Concerning battery life, the SL1 gets 380 shots out of its Canon LP-E12 battery, while the A3000 can take 470 images on a single charge of its Sony NP-FW50 power pack. The power pack in the A3000 can be charged via the USB port, which can be very convenient when travelling.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The A3000 was launched at a markedly lower price (by 40 percent) than the SL1, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the A3000 is 8 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (SL1) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 19.8MP, the A3000 offers a higher resolution than the SL1 (17.9MP), but the A3000 has marginally smaller individual pixels (pixel pitch of 4.25μm versus 4.31μm for the SL1). Yet, the A3000 is a somewhat more recent model (by 5 months) than the SL1, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Sony A3000 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A3000 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 SL1 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 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 Sony Alpha A3000 are ISO 100 to ISO 16000 (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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 consideration, the A3000 offers substantially better image quality than the SL1 (overall score 15 points higher). The advantage is based on 1.9 bits higher color depth, 1.5 EV in additional dynamic range, and 0.3 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 are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the A3000 provides a faster frame rate than the SL1. 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 A3000 has an electronic viewfinder (202k dots), while the SL1 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 A3000 offers a wider field of view (100%) than the one in the SL1 (95%), so that a larger proportion of the captured image is visible in the finder. On the other hand, the viewfinder of the SL1 has a higher magnification (0.54x vs 0.47x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Canon SL1 and Sony A3000 along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The SL1 has a touchscreen, while the A3000 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 A3000 uses SDXC or Memory Stick PRO Duo cards. The SL1 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the A3000 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 Rebel SL1 and Sony Alpha A3000 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the SL1 has a microphone port, which is missing on the A3000. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

Both the SL1 and the A3000 have been discontinued, but can regularly be found used on ebay. The SL1 was replaced by the Canon SL2, while the A3000 does not have a direct successor. Further information on the features and operation of the SL1 and A3000 can be found, respectively, in the Canon SL1 Manual (free pdf) or the online Sony A3000 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Canon SL1 and the Sony A3000? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Canon EOS Rebel SL1:

• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• Better sound: Can connect to an external microphone for higher quality sound recording.
• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.54x vs 0.47x).
• 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.
• Faster burst: Shoots at higher frequency (4.9 vs 2.5 flaps/sec) to capture the decisive moment.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More heavily discounted: Has been on the market for longer (launched in March 2013).

Advantages of the Sony Alpha A3000:

• More detail: Has more megapixels (19.8 vs 17.9MP), which boosts linear resolution by 5%.
• Better image quality: Scores substantially higher (15 points) in the DXO overall evaluation.
• Richer colors: Generates noticeably more natural colors (1.9 bits more color depth).
• More dynamic range: Captures a broader range of light and dark details (1.5 EV of extra DR).
• Better low-light sensitivity: Can shoot in dim conditions (0.3 stops ISO advantage).
• 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%).
• Longer lasting: Gets more shots (470 versus 380) out of a single battery charge.
• Easier travel charging: Can be conveniently charged via its USB port.
• More legacy lens friendly: Can use many non-native lenses via adapters.
• More affordable: Was introduced into a lower priced category (40 percent cheaper at launch).
• More modern: Was introduced somewhat (5 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the A3000 is the clear winner of the contest (13 : 9 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 SL1 and the Sony A3000 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the SL1 or the A3000 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 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.

Care should be taken when interpreting the review scores above, 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.
