Canon 30D vs Sony NEX-C3
The Canon EOS 30D and the Sony Alpha NEX-C3 are two digital cameras that were officially introduced, respectively, in February 2006 and June 2011. The 30D 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 8.2 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 30D 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.
An illustration of the physical size and weight of the Canon 30D and the Sony NEX-C3 is provided 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 size dimensions are rounded to the nearest millimeter.
The NEX-C3 can be obtained in three different colors (black, silver, pink), while the 30D 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 (57 percent) than the Canon 30D. Moreover, the NEX-C3 is substantially lighter (71 percent) than the 30D. In this context, it is worth noting that neither the 30D 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 (30D) 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 table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The NEX-C3 was launched at a markedly lower price (by 57 percent) than the 30D, which puts it into a different market segment. 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 imaging sensor is a crucial determinant 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 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 8 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (30D) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 16MP, the NEX-C3 offers a higher resolution than the 30D (8.2MP), but the NEX-C3 has smaller individual pixels (pixel pitch of 4.78μm versus 6.42μm for the 30D). Yet, the NEX-C3 is a much more recent model (by 5 years and 3 months) than the 30D, 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 30D are 17.5 x 11.7 inches or 44.5 x 29.7 cm for good quality, 14 x 9.3 inches or 35.6 x 23.7 cm for very good quality, and 11.7 x 7.8 inches or 29.7 x 19.8 cm for excellent quality prints.
The Canon EOS 30D has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. 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 determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under consideration, the NEX-C3 offers substantially better image quality than the 30D (overall score 14 points higher). The advantage is based on 1.2 bits higher color depth, 1.4 EV in additional dynamic range, and 0.6 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 can also record movies. The NEX-C3 indeed provides for movie recording, while the 30D does not. The highest resolution format that the NEX-C3 can use is 720/30p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the 30D 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 adjacent table lists some of the other core features of the Canon 30D and Sony NEX-C3 along with similar information for a selection of comparators.
One difference between the cameras concerns the presence of an on-board flash. The 30D has one, while the NEX-C3 does not. While the built-in flash of the 30D 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 30D does not have a selfie-screen.
The 30D 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 30D and Sony Alpha NEX-C3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon 30D (unlike the NEX-C3) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 30D and the NEX-C3 have been discontinued, but can regularly be found used on eBay. The 30D was replaced by the Canon 40D, 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 conclusions can be drawn? Is there a clear favorite between the Canon 30D and the Sony NEX-C3? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Canon EOS 30D:
- Easier framing: Has an optical viewfinder for image composition and settings control.
- Easier setting verification: Features an LCD display on top to control shooting parameters.
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Longer lasting: Can take more shots (750 versus 400) on a single battery charge.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- More heavily discounted: Has been available for much longer (launched in February 2006).
Arguments in favor of the Sony Alpha NEX-C3:
- More detail: Has more megapixels (16 vs 8.2MP), which boosts linear resolution by 40%.
- Better image quality: Scores substantially higher (14 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (1.2 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (1.4 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (0.6 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.
- More compact: Is smaller (110x60mm vs 144x106mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 560g or 71 percent) and is thus easier to take along.
- More legacy lens friendly: Can use many non-native lenses via adapters.
- More affordable: Was introduced into a lower priced category (57 percent cheaper at launch).
- More modern: Reflects 5 years and 3 months of technical progress since the 30D 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 : 7 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.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the 30D or the NEX-C3 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 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.

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
