Canon 100D vs Sony A3000
The Canon EOS 100D (called Canon SL1 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 100D 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 100D 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.
The physical size and weight of the Canon 100D 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 100D 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 100D. Moreover, the A3000 is slightly heavier (1 percent) than the 100D. In this context, it is worth noting that neither the 100D 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 (100D) 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 100D gets 380 shots out of its LP-E12 battery, while the A3000 can take 470 images on a single charge of its 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 100D, 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.
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 (100D) 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 100D (17.9MP), but the A3000 has marginally smaller individual pixels (pixel pitch of 4.25μm versus 4.31μm for the 100D). Yet, the A3000 is a somewhat more recent model (by 5 months) than the 100D, 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 inch or 69.3 x 46.1 cm, for very good quality (250 dpi) 21.8 x 14.5 inch or 55.4 x 36.9 cm, and for excellent quality (300 dpi) 18.2 x 12.1 inch or 46.2 x 30.8 cm. The corresponding values for the Canon 100D are 25.9 x 17.3 inch or 65.8 x 43.9 cm for good quality, 20.7 x 13.8 inch or 52.7 x 35.1 cm for very good quality, and 17.3 x 11.5 inch 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 A3000 are ISO 100 to ISO 16000 (no boost).
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 100D (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 100D. It can shoot movie footage at 1080/60i, while the Canon is limited to 1080/30p.
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 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 A3000 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. On the other hand, the viewfinder of the 100D 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 100D 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 100D has a touchscreen, while the A3000 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 A3000 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 A3000 cannot take advantage of Ultra High Speed SD cards.
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 A3000 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 100D 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 100D and the A3000 have been discontinued, but can regularly be found used on eBay. The 100D was replaced by the Canon 200D, while the A3000 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 Sony websites.
So how do things add up? Is there a clear favorite between the Canon 100D 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 100D:
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.

If the count of individual advantages (bullet points above) is taken as a guide, the A3000 emerges as the winner of the match-up (12 : 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 100D 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 100D 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.
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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.
