Canon 350D vs Olympus E-420
The Canon EOS 350D (called Canon XT in some regions) and the Olympus E-420 are two digital cameras that were announced, 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 megapixels, whereas the Olympus provides 10 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 Olympus E-420? 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 Olympus E-420
The physical size and weight of the Canon 350D and the Olympus E-420 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 dimensions are rounded to the nearest millimeter.
The 350D can be obtained in two different colors (black, silver), while the E-420 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 350D and the Olympus E-420 are 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 compare the optics available 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.

|Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.|
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.
Sensor comparison: Canon 350D vs Olympus E-420
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. 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 tend to be more expensive and lead to bigger and heavier cameras 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.
In terms of underlying technology, both cameras are build around CMOS sensors.
Despite having a smaller sensor, the E-420 offers a higher resolution of 10 megapixels, compared with 8 MP of the 350D. This megapixels 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.
The resolution advantage of the Olympus E-420 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-420 for good quality output (200 dots per inch) amounts to 18.2 x 13.7 inch or 46.3 x 34.7 cm, for very good quality (250 dpi) 14.6 x 10.9 inch or 37.1 x 27.8 cm, and for excellent quality (300 dpi) 12.2 x 9.1 inch or 30.9 x 23.2 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 Olympus E-420 offers exactly the same ISO settings.
Consistent information on actual sensor performance is available from DXO Mark for many 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Feature comparison: Canon 350D vs Olympus E-420
Beyond 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 viewfinders of both cameras offer the same field of view (95%), but the viewfinder of the 350D has a higher magnification than the one of the E-420 (0.49x vs 0.46x), 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 Olympus E-420 along with similar information for a selection of comparators.

The 350D writes its imaging data to Compact Flash cards, while the E-420 uses Compact Flash or xD Picture cards. The E-420 features dual card slots, which can be very useful in case a memory card fails. In contrast, the 350D only has one slot.
Connectivity comparison: Canon 350D vs Olympus E-420
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 Olympus E-420 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the 350D and the E-420 have been discontinued, but can regularly be found used on eBay. The 350D was replaced by the Canon 400D, while the E-420 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 Olympus websites.
Review summary: Canon 350D vs Olympus E-420
So what is the bottom line? Is the Canon 350D better than the Olympus E-420 or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Canon EOS 350D:
- Better image quality: Scores markedly higher (4 points) in the DXO overall assessment.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.49x vs 0.46x).
- 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.
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- 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 (9 : 3 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 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 Olympus E-420 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the 350D and the E-420 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 Olympus E-420
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 (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.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
