Canon T3 vs Sony NEX-3
The Canon EOS Rebel T3 (called Canon 1100D in some regions) and the Sony Alpha NEX-3 are two digital cameras that were officially introduced, respectively, in February 2011 and May 2010. The T3 is a DSLR, while the NEX-3 is a mirrorless interchangeable lens camera. Both cameras are equipped with an APS-C sensor. The Canon has a resolution of 12.2 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 T3 and the Sony Alpha NEX-3? 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 side-by-side display below illustrates the physical size and weight of the Canon T3 and the Sony NEX-3. 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 width, height and depth dimensions are rounded to the nearest millimeter.
The NEX-3 can be obtained in three different colors (black, silver, red), while the T3 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-3 is considerably smaller (44 percent) than the Canon T3. Moreover, the NEX-3 is substantially lighter (40 percent) than the T3. In this context, it is worth noting that neither the T3 nor the NEX-3 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 (T3) and the Sony E-Mount Lens Catalog (NEX-3). Mirrorless cameras, such as the NEX-3, 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. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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 T3 was launched at a somewhat lower price (by 25 percent) than the NEX-3, 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.
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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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-3 is 13 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (T3) 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.
With 14MP, the NEX-3 offers a higher resolution than the T3 (12.2MP), but the NEX-3 has marginally smaller individual pixels (pixel pitch of 5.11μm versus 5.15μm for the T3). It is noteworthy in this context that the T3 is a somewhat more recent model (by 8 months) than the NEX-3, 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 Sony NEX-3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the NEX-3 for good quality output (200 dots per inch) amounts to 23 x 15.3 inches or 58.3 x 38.8 cm, for very good quality (250 dpi) 18.4 x 12.2 inches or 46.7 x 31 cm, and for excellent quality (300 dpi) 15.3 x 10.2 inches or 38.9 x 25.9 cm. The corresponding values for the Canon T3 are 21.4 x 14.2 inches or 54.3 x 36.2 cm for good quality, 17.1 x 11.4 inches or 43.4 x 28.9 cm for very good quality, and 14.2 x 9.5 inches or 36.2 x 24.1 cm for excellent quality prints.
The Canon EOS Rebel T3 has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the Sony Alpha NEX-3 are ISO 200 to ISO 12800 (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 NEX-3 has a markedly higher DXO score than the T3 (overall score 6 points higher), which will translate into better image quality. The advantage is based on 0.2 bits higher color depth, 1 EV in additional dynamic range, and 0.1 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 are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (720/30p).
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the T3 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the NEX-3 relies on live view and the rear LCD for framing. That said, the NEX-3 can be equipped with an optional viewfinder – the FDA-SV1. The following table reports on some other key feature differences and similarities of the Canon T3, the Sony NEX-3, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The T3 has one, while the NEX-3 does not. While the built-in flash of the T3 is not very powerful, it can at times be useful as a fill-in light.The NEX-3 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 T3 does not have a selfie-screen.
The T3 writes its imaging data to SDXC cards, while the NEX-3 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 T3 and Sony Alpha NEX-3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the T3 and the NEX-3 have been discontinued, but can regularly be found used on eBay. The NEX-3 was replaced by the Sony NEX-3N, while the T3 was followed by the Canon T5. 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? Which of the two cameras – the Canon T3 or the Sony NEX-3 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Canon EOS Rebel T3:
- Easier framing: Has an optical viewfinder for image composition and settings control.
- Longer lasting: Can take more shots (700 versus 330) on a single battery charge.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More affordable: Was introduced into a lower priced segment (25 percent cheaper at launch).
- More modern: Is somewhat more recent (announced 8 months after the NEX-3).
Arguments in favor of the Sony Alpha NEX-3:
- More detail: Has more megapixels (14 vs 12.2MP), which boosts linear resolution by 7%.
- Better image quality: Scores markedly higher (6 points) in the DXO overall evaluation.
- More dynamic range: Captures a broader range of light and dark details (1 EV of extra DR).
- Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (920k vs 230k dots).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (7 vs 3 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (117x62mm vs 130x100mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 198g or 40 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 on the market for longer (launched in May 2010).
If the count of individual advantages (bullet points above) is taken as a guide, the NEX-3 is the clear winner of the contest (12 : 5 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. 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 T3 and the Sony NEX-3 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 T3 and the NEX-3 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.
This is where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major camera 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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
