Canon 350D vs 40D
The Canon EOS 350D (called Canon XT in some regions) and the Canon EOS 40D are two digital cameras that were officially introduced, respectively, in February 2005 and August 2007. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The 350D has a resolution of 8 megapixels, whereas the 40D provides 10.1 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 350D and the Canon EOS 40D? 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: Canon 350D vs 40D
The physical size and weight of the Canon 350D and the Canon 40D are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter.
The 350D can be obtained in two different colors (black, silver), while the 40D 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 Canon 40D is notably larger (32 percent) than the Canon 350D. Moreover, the 40D is substantially heavier (52 percent) than the 350D. In this context, it is worth noting that neither the 350D nor the 40D 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Canon EF Lens Catalog.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

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 350D was launched at a markedly lower price (by 31 percent) than the 40D, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
Sensor comparison: Canon 350D vs 40D
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. 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 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 40D is 1 percent bigger. They nevertheless have the same format factor of 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Technology-wise, the 40D uses a more advanced image processing engine (DIGIC 3) than the 350D (DIGIC II), with benefits for noise reduction, color accuracy, and processing speed.
With 10.1MP, the 40D offers a higher resolution than the 350D (8MP), but the 40D has smaller individual pixels (pixel pitch of 5.73μm versus 6.41μm for the 350D). Yet, the 40D is a much more recent model (by 2 years and 6 months) than the 350D, 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 Canon 40D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 40D for good quality output (200 dots per inch) amounts to 19.4 x 13 inch or 49.4 x 32.9 cm, for very good quality (250 dpi) 15.6 x 10.4 inch or 39.5 x 26.3 cm, and for excellent quality (300 dpi) 13 x 8.6 inch or 32.9 x 21.9 cm. The corresponding values for the Canon 350D are 17.3 x 11.5 inch or 43.9 x 29.3 cm for good quality, 13.8 x 9.2 inch or 35.1 x 23.4 cm for very good quality, and 11.5 x 7.7 inch or 29.3 x 19.5 cm for excellent quality prints.
The Canon EOS 350D has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Canon EOS 40D are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 100-3200.
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 40D has a markedly higher DXO score than the 350D (overall score 4 points higher), which will translate into better image quality. The advantage is based on 0.3 bits higher color depth, 0.5 EV in additional dynamic range, and 0.1 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Feature comparison: Canon 350D vs 40D
Beyond body and sensor, cameras can and do differ across a range of features. The 350D and the 40D are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The viewfinders of both cameras offer the same field of view (95%), but the viewfinder of the 40D has a higher magnification than the one of the 350D (0.59x vs 0.49x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Canon 350D, the Canon 40D, and comparable cameras.

One feature that is present on the 40D, but is missing on the 350D is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.
Concerning the storage of imaging data, both the 350D and the 40D write their files to Compact Flash cards.
Connectivity comparison: Canon 350D vs 40D
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 350D and Canon EOS 40D and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Canon 40D (unlike the 350D) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the 350D and the 40D have been discontinued, but can regularly be found used on eBay. The 350D was replaced by the Canon 400D, while the 40D was followed by the Canon 50D. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
Review summary: Canon 350D vs 40D
So how do things add up? Is the Canon 350D better than the Canon 40D or vice versa? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Canon EOS 350D:
- More compact: Is smaller (127x94mm vs 146x108mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 282g or 34 percent) and hence easier to carry around.
- More affordable: Was introduced into a lower priced category (31 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in February 2005).
Reasons to prefer the Canon EOS 40D:
- More detail: Has more megapixels (10.1 vs 8MP), which boosts linear resolution by 12%.
- Better image quality: Scores markedly higher (4 points) in the DXO overall evaluation.
- Better jpgs: Has a more modern image processing engine (DIGIC 3 vs DIGIC II).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.59x vs 0.49x).
- Easier setting verification: Features a control panel on top to check shooting parameters.
- Larger screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (230k vs 115k dots).
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Faster burst: Shoots at higher frequency (6.5 vs 3 flaps/sec) to capture the decisive moment.
- Longer lasting: Gets more shots (750 versus 400) out of a single battery charge.
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- More modern: Reflects 2 years and 6 months of technical progress since the 350D launch.
If the count of individual advantages (bullet points above) is taken as a guide, the 40D is the clear winner of the contest (12 : 4 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 350D and the Canon 40D place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing whether the two cameras rank among the cream of the crop.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the 350D and the 40D in practical situations. 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: Canon 350D vs 40D
This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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. 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.
