Canon 350D vs 70D
The Canon EOS 350D (called Canon XT in some regions) and the Canon EOS 70D are two digital cameras that were announced, respectively, in February 2005 and July 2013. 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 70D provides 20 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 70D? 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 350D and the Canon 70D are illustrated in the side-by-side display below. 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 size dimensions are rounded to the nearest millimeter.
The 350D can be obtained in two different colors (black, silver), while the 70D 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 70D is notably larger (21 percent) than the Canon 350D. Moreover, the 70D is substantially heavier (40 percent) than the 350D. It is noteworthy in this context that the 70D is splash and dust-proof, while the 350D does not feature any corresponding weather-sealing.
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 following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 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 350D was launched at a somewhat lower price (by 25 percent) than the 70D, 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 imaging sensor is a crucial determinant of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 70D is 3 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 70D uses a more advanced image processing engine (DIGIC 5+) than the 350D (DIGIC II), with benefits for noise reduction, color accuracy, and processing speed.
With 20MP, the 70D offers a higher resolution than the 350D (8MP), but the 70D has smaller individual pixels (pixel pitch of 4.11μm versus 6.41μm for the 350D). Yet, the 70D is a much more recent model (by 8 years and 4 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 70D implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 70D for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Canon 350D are 17.3 x 11.5 inches or 43.9 x 29.3 cm for good quality, 13.8 x 9.2 inches or 35.1 x 23.4 cm for very good quality, and 11.5 x 7.7 inches or 29.3 x 19.5 cm for excellent quality prints.
The 70D has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS 350D has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Canon EOS 70D are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 100-25600.
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.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 70D has a markedly higher DXO score than the 350D (overall score 8 points higher), which will translate into better image quality. The advantage is based on 0.7 bits higher color depth, 0.8 EV in additional dynamic range, and 0.5 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.
|7.||Canon G3 X||1-inch||20.0||5472||3648||1080/60p||21.4||12.3||521||63|

Many modern cameras cannot only take still pictures, but also record videos. The 70D indeed provides for movie recording, while the 350D does not. The highest resolution format that the 70D can use is 1080/30p.
Beyond body and sensor, cameras can and do differ across a range of features. The 350D and the 70D 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 viewfinder in the 70D offers a wider field of view (98%) than the one in the 350D (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the 70D has a higher magnification (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 adjacent table lists some of the other core features of the Canon 350D and Canon 70D along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The 70D has a touchscreen, while the 350D has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The 70D 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 350D does not have a selfie-screen.
The 350D writes its imaging data to Compact Flash cards, while the 70D uses SDXC 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 350D and Canon EOS 70D and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 70D offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the 350D does not provide wifi capability.
Both the 350D and the 70D have been discontinued, but can regularly be found used on ebay. The 350D was replaced by the Canon 400D, while the 70D was followed by the Canon 80D. Further information on the features and operation of the 350D and 70D can be found, respectively, in the Canon 350D Manual (free pdf) or the online Canon 70D Manual.
So what is the bottom line? Is the Canon 350D better than the Canon 70D or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Canon EOS 350D:
- More compact: Is smaller (127x94mm vs 139x104mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 215g or 28 percent) and hence easier to carry around.
- More affordable: Was introduced into a lower priced segment (25 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in February 2005).
Arguments in favor of the Canon EOS 70D:
- More detail: Has more megapixels (20 vs 8MP), which boosts linear resolution by 58%.
- Better image quality: Scores markedly higher (8 points) in the DXO overall evaluation.
- More dynamic range: Captures a broader range of light and dark details (0.8 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (0.5 stops ISO advantage).
- Better jpgs: Has a more modern image processing engine (DIGIC 5+ vs DIGIC II).
- Broader imaging potential: Can capture not only stills but also 1080/30p video.
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- More complete view: Has a viewfinder with a larger field of view (98% vs 95%).
- 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 (1040k vs 115k dots).
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Faster burst: Shoots at higher frequency (7 vs 3 flaps/sec) to capture the decisive moment.
- Longer lasting: Gets more shots (920 versus 400) out of a single battery charge.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- More modern: Reflects 8 years and 4 months of technical progress since the 350D launch.
If the count of individual advantages (bullet points above) is taken as a guide, the 70D is the clear winner of the contest (21 : 4 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro 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 70D 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 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 350D and the 70D 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.
This is why hands-on reviews by experts are important. 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.

The above review scores should be interpreted 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 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.
