Canon T3i vs Sony NEX-5R
The Canon EOS Rebel T3i (called Canon 600D in some regions) and the Sony Alpha NEX-5R are two digital cameras that were revealed to the public, respectively, in February 2011 and August 2012. The T3i is a DSLR, while the NEX-5R 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 16 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 T3i and the Sony Alpha NEX-5R? 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 T3i and the Sony NEX-5R are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter.
The NEX-5R can be obtained in two different colors (black, silver), while the T3i 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 NEX-5R is considerably smaller (51 percent) than the Canon T3i. Moreover, the NEX-5R is substantially lighter (52 percent) than the T3i. In this context, it is worth noting that neither the T3i nor the NEX-5R 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 (T3i) and the Sony E-Mount Lens Catalog (NEX-5R). Mirrorless cameras, such as the NEX-5R, 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.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

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 T3i was launched at a somewhat lower price (by 20 percent) than the NEX-5R, 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.
The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels 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.
Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the NEX-5R is 10 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (T3i) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
In terms of underlying technology, both cameras are build around CMOS sensors.
Despite having a smaller sensor, the Canon T3i offers a higher resolution of 17.9 megapixels, compared with 16 MP of the Sony NEX-5R. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.31μm versus 4.78μm for the NEX-5R). Moreover, it should be noted that the NEX-5R is a somewhat more recent model (by 1 year and 6 months) than the T3i, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Canon T3i implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T3i 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 Sony NEX-5R are 24.6 x 16.3 inches or 62.4 x 41.5 cm for good quality, 19.6 x 13.1 inches or 49.9 x 33.2 cm for very good quality, and 16.4 x 10.9 inches or 41.6 x 27.6 cm for excellent quality prints.
The Canon EOS Rebel T3i 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 NEX-5R are ISO 100 to ISO 25600 (no boost).
For many cameras, data on sensor performance has been reported by DXO Mark. 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 NEX-5R offers substantially better image quality than the T3i (overall score 13 points higher). The advantage is based on 1.6 bits higher color depth, 1.6 EV in additional dynamic range, and 0.2 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 are equipped with sensors that have a sufficiently high read-out speed for moving images, but the NEX-5R provides a faster frame rate than the T3i. 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 T3i has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the NEX-5R relies on live view and the rear LCD for framing. That said, the NEX-5R can be equipped with an optional viewfinder – the FDA-EV1S. The table below summarizes some of the other core capabilities of the Canon T3i and Sony NEX-5R in connection with corresponding information for a sample of similar cameras.
One difference between the cameras concerns the presence of an on-board flash. The T3i has one, while the NEX-5R does not. While the built-in flash of the T3i is not very powerful, it can at times be useful as a fill-in light.Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.
The T3i writes its imaging data to SDXC cards, while the NEX-5R uses SDXC or Memory Stick PRO Duo 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 Rebel T3i and Sony Alpha NEX-5R and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the T3i has a microphone port, which is missing on the NEX-5R. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
Both the T3i and the NEX-5R have been discontinued, but can regularly be found used on eBay. The T3i was replaced by the Canon T4i, while the NEX-5R was followed by the Sony NEX-5T. 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 what conclusions can be drawn? Which of the two cameras – the Canon T3i or the Sony NEX-5R – 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.
Advantages of the Canon EOS Rebel T3i:
- More detail: Offers more megapixels (17.9 vs 16MP) with a 6% higher linear resolution.
- Better sound: Can connect to an external microphone for higher quality sound recording.
- Easier framing: Has an optical viewfinder for image composition and settings control.

- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- Faster burst: Shoots at higher frequency (10 vs 3.7 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (111x59mm vs 133x100mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 294g or 52 percent) and is thus easier to take along.
- 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.
- More modern: Was introduced somewhat (1 year and 6 months) more recently.
If the count of relative strengths (bullet points above) is taken as a measure, the NEX-5R emerges as the winner of the match-up (11 : 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 T3i and the Sony NEX-5R 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 T3i or the NEX-5R perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.
This is where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], 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 review scores listed above should be treated 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
