Canon XTi vs Sony NEX-C3
The Canon EOS Rebel XTi (called Canon 400D in some regions) and the Sony Alpha NEX-C3 are two digital cameras that were announced, respectively, in August 2006 and June 2011. The XTi is a DSLR, while the NEX-C3 is a mirrorless interchangeable lens camera. Both cameras are equipped with an APS-C sensor. The Canon has a resolution of 10.1 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 XTi and the Sony Alpha NEX-C3? 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 XTi and the Sony NEX-C3 are illustrated in the side-by-side display below. 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 measures are rounded to the nearest millimeter.
The NEX-C3 can be obtained in three different colors (black, silver, pink), while the XTi 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-C3 is considerably smaller (38 percent) than the Canon XTi. Moreover, the NEX-C3 is substantially lighter (60 percent) than the XTi. In this context, it is worth noting that neither the XTi nor the NEX-C3 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 (XTi) and the Sony E-Mount Lens Catalog (NEX-C3). Mirrorless cameras, such as the NEX-C3, 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 adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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.

The price is, of course, an important factor in any camera decision. 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-C3 was launched at a somewhat lower price (by 25 percent) than the XTi, which makes it more attractive for photographers on a tight budget. 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.
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. 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 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 NEX-C3 is 11 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (XTi) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
With 16MP, the NEX-C3 offers a higher resolution than the XTi (10.1MP), but the NEX-C3 has smaller individual pixels (pixel pitch of 4.78μm versus 5.71μm for the XTi). Yet, the NEX-C3 is a much more recent model (by 4 years and 9 months) than the XTi, 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 NEX-C3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the NEX-C3 for good quality output (200 dots per inch) amounts to 24.6 x 16.3 inches or 62.4 x 41.5 cm, for very good quality (250 dpi) 19.6 x 13.1 inches or 49.9 x 33.2 cm, and for excellent quality (300 dpi) 16.4 x 10.9 inches or 41.6 x 27.6 cm. The corresponding values for the Canon XTi are 19.4 x 13 inches or 49.4 x 32.9 cm for good quality, 15.6 x 10.4 inches or 39.5 x 26.3 cm for very good quality, and 13 x 8.6 inches or 32.9 x 21.9 cm for excellent quality prints.
The Canon EOS Rebel XTi has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Sony Alpha NEX-C3 are ISO 100 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-C3 offers substantially better image quality than the XTi (overall score 11 points higher). The advantage is based on 0.6 bits higher color depth, 1.2 EV in additional dynamic range, and 0.7 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 are not only capable of taking still images, but also of capturing video footage. The NEX-C3 indeed provides for movie recording, while the XTi does not. The highest resolution format that the NEX-C3 can use is 720/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the XTi has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the NEX-C3 relies on live view and the rear LCD for framing. That said, the NEX-C3 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 XTi, the Sony NEX-C3, and comparable cameras.
One difference between the cameras concerns the presence of an on-board flash. The XTi has one, while the NEX-C3 does not. While the built-in flash of the XTi is not very powerful, it can at times be useful as a fill-in light.The NEX-C3 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 XTi does not have a selfie-screen.
The XTi writes its imaging data to Compact Flash cards, while the NEX-C3 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 XTi and Sony Alpha NEX-C3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the XTi and the NEX-C3 have been discontinued, but can regularly be found used on eBay. The XTi was replaced by the Canon Xsi, while the NEX-C3 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 what is the bottom line? Is the Canon XTi better than the Sony NEX-C3 or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Canon EOS Rebel XTi:
- Easier framing: Has an optical viewfinder for image composition and settings control.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More heavily discounted: Has been available for much longer (launched in August 2006).
Reasons to prefer the Sony Alpha NEX-C3:
- More detail: Has more megapixels (16 vs 10.1MP), which boosts linear resolution by 26%.
- Better image quality: Scores substantially higher (11 points) in the DXO overall evaluation.
- More dynamic range: Captures a broader range of light and dark details (1.2 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (0.7 stops ISO advantage).
- Broader imaging potential: Can capture not only stills but also 720/30p video.
- Larger screen: Has a bigger rear LCD (3.0" vs 2.5") 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 (5.5 vs 3 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (110x60mm vs 127x84mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 331g or 60 percent) and is thus easier to take along.
- More legacy lens friendly: Can use many non-native lenses via adapters.
- More affordable: Was released into a lower priced segment (25 percent cheaper at launch).
- More modern: Reflects 4 years and 9 months of technical progress since the XTi launch.
If the number of relative strengths (bullet points above) is taken as a guide, the NEX-C3 is the clear winner of the contest (15 : 3 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 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 XTi and the Sony NEX-C3 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 XTi or the NEX-C3 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 expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
