Canon T7i vs Sony NEX-5

The Canon EOS Rebel T7i (called Canon 800D in some regions) and the Sony Alpha NEX-5 are two digital cameras that were officially introduced, respectively, in February 2017 and May 2010. The T7i is a DSLR, while the NEX-5 is a mirrorless interchangeable lens camera. Both cameras are equipped with an APS-C sensor. The Canon has a resolution of 24 megapixels, whereas the Sony provides 14 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 T7i and the Sony Alpha NEX-5? 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 side-by-side display below illustrates the physical size and weight of the Canon T7i and the Sony NEX-5. 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 NEX-5 can be obtained in two different colors (black, silver), while the T7i 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-5 is considerably smaller (50 percent) than the Canon T7i. Moreover, the NEX-5 is substantially lighter (46 percent) than the T7i. In this context, it is worth noting that neither the T7i nor the NEX-5 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 (T7i) and the Sony E-Mount Lens Catalog (NEX-5). Mirrorless cameras, such as the NEX-5, 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 T7i gets 600 shots out of its Canon LP-E17 battery, while the NEX-5 can take 330 images on a single charge of its Sony NP-FW50 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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 NEX-5 was somewhat cheaper (by 7 percent) than the T7i 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 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. 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 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-5 is 10 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (T7i) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Despite having a smaller sensor, the Canon T7i offers a higher resolution of 24 megapixels, compared with 14 MP of the Sony NEX-5. 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 3.72μm versus 5.11μm for the NEX-5). However, it should be noted that the T7i is much more recent (by 6 years and 9 months) than the NEX-5, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.

The resolution advantage of the Canon T7i implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the T7i for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Sony NEX-5 are 23 x 15.3 inches or 58.3 x 38.8 cm for good quality, 18.4 x 12.2 inches or 46.7 x 31 cm for very good quality, and 15.3 x 10.2 inches or 38.9 x 25.9 cm for excellent quality prints.

The T7i has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS Rebel T7i has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 100-51200. The corresponding ISO settings for the Sony Alpha NEX-5 are ISO 200 to ISO 12800 (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.

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. 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 are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the T7i provides a higher frame rate than the NEX-5. It can shoot video footage at 1080/60p, while the Sony is limited to 1080/60i.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the T7i has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the NEX-5 relies on live view and the rear LCD for framing. That said, the NEX-5 can be equipped with an optional viewfinder – the FDA-SV1. The adjacent table lists some of the other core features of the Canon T7i and Sony NEX-5 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The T7i has one, while the NEX-5 does not. While the built-in flash of the T7i is not very powerful, it can at times be useful as a fill-in light.

The T7i writes its imaging data to SDXC cards, while the NEX-5 uses SDXC or Memory Stick PRO Duo cards. The T7i supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the NEX-5 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 T7i and Sony Alpha NEX-5 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the T7i has a microphone port, which is missing on the NEX-5. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.

Both the T7i and the NEX-5 have been discontinued, but can regularly be found used on ebay. The NEX-5 was replaced by the Sony NEX-5N, while the T7i was followed by the Canon T8i. Further information on the features and operation of the T7i and NEX-5 can be found, respectively, in the Canon T7i Manual (free pdf) or the online Sony NEX-5 Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Canon T7i and the Sony NEX-5? Which camera is better? The listing below highlights the relative strengths of the two models.

Advantages of the Canon EOS Rebel T7i:

• More detail: Offers more megapixels (24 vs 14MP) with a 31% higher linear resolution.
• Better video: Provides higher movie framerates (1080/60p versus 1080/60i).
• 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.
• Easier framing: Has an optical viewfinder for image composition and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 920k dots).
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• Longer lasting: Can take more shots (600 versus 330) on a single battery charge.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• 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.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Reflects 6 years and 9 months of technical progress since the NEX-5 launch.

Arguments in favor of the Sony Alpha NEX-5:

• Faster burst: Shoots at higher frequency (7 vs 6 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (111x59mm vs 131x100mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 245g or 46 percent) and is thus easier to take along.
• More legacy lens friendly: Can use many non-native lenses via adapters.
• More heavily discounted: Has been around for much longer (launched in May 2010).

If the number of relative strengths (bullet points above) is taken as a guide, the T7i is the clear winner of the match-up (15 : 5 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 T7i and the Sony NEX-5 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the T7i or the NEX-5. 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 adjacent summary-table relays the overall verdicts of several of the most popular 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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
