Canon 550D vs Sony A5100

The Canon EOS 550D (called Canon T2i in some regions) and the Sony Alpha A5100 are two digital cameras that were announced, respectively, in February 2010 and August 2014. The 550D is a DSLR, while the A5100 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 24 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 550D and the Sony Alpha A5100? 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: Canon 550D vs Sony A5100

An illustration of the physical size and weight of the Canon 550D and the Sony A5100 is provided 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 A5100 can be obtained in two different colors (black, white), while the 550D is only available in black.

Compare 550D versus A5100 top
Comparison 550D or A5100 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A5100 is considerably smaller (45 percent) than the Canon 550D. Moreover, the A5100 is substantially lighter (47 percent) than the 550D. In this context, it is worth noting that neither the 550D nor the A5100 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 (550D) and the Sony E-Mount Lens Catalog (A5100). Mirrorless cameras, such as the A5100, 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 550D gets 440 shots out of its LP-E8 battery, while the A5100 can take 400 images on a single charge of its NP-FW50 power pack. The power pack in the A5100 can be charged via the USB port, which can be very convenient when travelling.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

Any camera decision will obviously take relative prices into account. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The A5100 was launched at a somewhat lower price (by 21 percent) than the 550D, 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: Canon 550D vs Sony A5100

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 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 A5100 is 11 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (550D) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon 550D and Sony A5100 sensor measures

With 24MP, the A5100 offers a higher resolution than the 550D (17.9MP), but the A5100 has smaller individual pixels (pixel pitch of 3.91μm versus 4.31μm for the 550D). Yet, the A5100 is a much more recent model (by 4 years and 6 months) than the 550D, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Sony A5100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A5100 for good quality output (200 dots per inch) amounts to 30 x 20 inch or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inch or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inch or 50.8 x 33.9 cm. The corresponding values for the Canon 550D 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 A5100 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS 550D has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 100-12800. The corresponding ISO settings for the Sony Alpha A5100 are ISO 100 to ISO 25600 (no boost).

550D versus A5100 MP

For many cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under consideration, the A5100 offers substantially better image quality than the 550D (overall score 14 points higher). The advantage is based on 1.7 bits higher color depth, 1.2 EV in additional dynamic range, and 0.8 stops in additional 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 A5100 provides a faster frame rate than the 550D. It can shoot movie footage at 1080/60p, while the Canon is limited to 1080/30p.

 

Feature comparison: Canon 550D vs Sony A5100

Beyond body and sensor, cameras can and do differ across a range of features. For example, the 550D has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the A5100 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Canon 550D, the Sony A5100, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The A5100 has a touchscreen, while the 550D has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The A5100 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the 550D does not have a selfie-screen.

The 550D writes its imaging data to SDXC cards, while the A5100 uses SDXC or Memory Stick PRO Duo cards. The A5100 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the 550D cannot take advantage of Ultra High Speed SD cards.

 

Connectivity comparison: Canon 550D vs Sony A5100

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.

It is notable that the 550D has a hotshoe, while the A5100 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

The A5100 is a recent model that features in the current product line-up of Sony. In contrast, the 550D has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 550D was succeeded by the Canon 600D. 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.


Review summary: Canon 550D vs Sony A5100

So what conclusions can be drawn? Which of the two cameras – the Canon 550D or the Sony A5100 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

ilogo

  • Faster burst: Shoots at higher frequency (6 vs 3.7 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (110x63mm vs 129x98mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 247g or 47 percent) and is thus easier to take along.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More affordable: Was released into a lower priced segment (21 percent cheaper at launch).
  • More modern: Reflects 4 years and 6 months of technical progress since the 550D launch.

If the number of relative strengths (bullet points above) is taken as a guide, the A5100 is the clear winner of the contest (19 : 5 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 550D and the Sony A5100 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 comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says little about, for example, the shooting experience and imaging performance of the 550D and the A5100 in practical situations. 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: Canon 550D vs Sony A5100

This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
