Canon 350D versus Olympus E-420
The Canon EOS 350D (called XT in some regions) and the Olympus E-420 are two digital cameras that were officially introduced, respectively, in February 2005 and March 2008. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (350D) and a Four Thirds (E-420) sensor. The Canon has a resolution of 8 megapixel, whereas the Olympus provides 10 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.
Body comparison: Canon 350D vs Olympus E-420
An illustration of the physical size and weight of the Canon 350D and the Olympus E-420 is provided in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth measures are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the 350D – represents 100 percent across all the size and weight measures).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 350D and the Olympus E-420are of equal size. However, the E-420 is markedly lighter (19 percent) than the 350D. In this context, it is worth noting that neither the 350D nor the E-420 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can find an overview of optics for the two cameras in the Canon EF Lens Catalog (350D) and the Four Thirds Lens Catalog (E-420).
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.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The E-420 was launched at a markedly lower price (by 33 percent) than the 350D, 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 Olympus E-420
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon 350D features an APS-C sensor and the Olympus E-420 a Four Thirds sensor. The sensor area in the E-420 is 32 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 2.0. The sensor in the 350D has a native 3:2 aspect ratio, while the one in the E-420 offers a 4:3 aspect.
Despite having a smaller sensor, the E-420 offers a higher resolution of 10 megapixel, compared with 8 MP of the 350D. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.74μm versus 6.41μm for the 350D). However, it should be noted that the E-420 is much more recent (by 3 years) than the 350D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
Consistent information on actual sensor performance is available from DXO Mark for most cameras. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under review, the 350D has a notably higher overall DXO score than the E-420 (overall score 4 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.3 bits higher color depth, 0.4 EV in additional dynamic range, and 0.3 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 Olympus E-420
Apart from body and sensor, cameras can and do differ across a range of features. The 350D and the E-420 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 following table reports on some other key feature differences and similarities of the Canon 350D, the Olympus E-420, and comparable cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

Review summary: Canon 350D vs Olympus E-420
So what conclusions can be drawn? Is there a clear favorite between the Canon 350D and the Olympus E-420? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Canon EOS 350D:
- Better image quality: Scores markedly higher (4 points) in the DXO overall assessment.
- More heavily discounted: Has been available for much longer (launched in February 2005).
Arguments in favor of the Olympus E-420:
- More detail: Has more megapixels (10 vs 8MP), which boosts linear resolution by 10%.
- Larger screen: Has a bigger rear LCD (2.7" vs 1.8") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (215k vs 115k dots).
- Faster burst: Shoots at higher frequency (3.5 vs 3 flaps/sec) to capture the decisive moment.
- Less heavy: Has a lower weight (by 100g or 19 percent) and is thus easier to take along.
- Longer lasting: Gets more shots (500 versus 400) out of a single battery charge.
- More affordable: Was introduced into a lower priced category (33 percent cheaper at launch).
- More modern: Reflects 3 years of technical progress since the 350D launch.
If the count of individual advantages (bullet points above) is taken as a guide, the E-420 is the clear winner of the contest (8 : 2 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.
In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the 350D or the E-420 handle or 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 where reviews by experts come in. The following table reports the overall rankings of the cameras as published by some of the major camera review sites.

The review scores listed above should be treated with care, though. The ratings are only valid when refering 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
