Canon SX420 vs Olympus E-P1
The Canon PowerShot SX420 IS and the Olympus PEN E-P1 are two digital cameras that were revealed to the public, respectively, in January 2016 and June 2009. The SX420 is a fixed lens compact, while the E-P1 is a mirrorless interchangeable lens camera. The cameras are based on a 1/2.3-inch (SX420) and a Four Thirds (E-P1) sensor. The Canon has a resolution of 19.9 megapixels, whereas the Olympus provides 12.2 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 PowerShot SX420 IS and the Olympus PEN E-P1? 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 SX420 and the Olympus E-P1 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 width, height and depth dimensions are rounded to the nearest millimeter.
The SX420 can be obtained in two different colors (black, red), while the E-P1 is available in three color-versions (black, silver, white).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-P1 is notably larger (18 percent) than the Canon SX420. In this context, it is worth noting that neither the SX420 nor the E-P1 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the SX420 has a lens built in, whereas the E-P1 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the E-P1 and their specifications in the Micro Four Thirds Lens Catalog.
Concerning battery life, the SX420 gets 195 shots out of its NB-11LH battery, while the E-P1 can take 300 images on a single charge of its BLS-1 power pack.
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.

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 SX420 was launched at a lower price than the E-P1, despite having a lens built in. 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. 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.
Of the two cameras under consideration, the Canon SX420 features a 1/2.3-inch sensor and the Olympus E-P1 a Four Thirds sensor. The sensor area in the E-P1 is 704 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 2.0. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.
Despite having a smaller sensor, the Canon SX420 offers a higher resolution of 19.9 megapixels, compared with 12.2 MP of the Olympus E-P1. 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 1.19μm versus 4.29μm for the E-P1). However, it should be noted that the SX420 is much more recent (by 6 years and 6 months) than the E-P1, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the SX420 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Canon SX420 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the SX420 for good quality output (200 dots per inch) amounts to 25.8 x 19.3 inches or 65.4 x 49.1 cm, for very good quality (250 dpi) 20.6 x 15.5 inches or 52.3 x 39.3 cm, and for excellent quality (300 dpi) 17.2 x 12.9 inches or 43.6 x 32.7 cm. The corresponding values for the Olympus E-P1 are 20.2 x 15.1 inches or 51.2 x 38.4 cm for good quality, 16.1 x 12.1 inches or 41 x 30.7 cm for very good quality, and 13.4 x 10.1 inches or 34.1 x 25.6 cm for excellent quality prints.
The Canon PowerShot SX420 IS has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Olympus PEN E-P1 are ISO 100 to ISO 6400 (no boost).
In terms of underlying technology, the SX420 is build around a CCD sensor, while the E-P1 uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the E-P1 provides a faster frame rate than the SX420. It can shoot movie footage at 720/30p, while the Canon is limited to 720/25p.
Beyond body and sensor, cameras can and do differ across a range of features. The SX420 and the E-P1 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. The adjacent table lists some of the other core features of the Canon SX420 and Olympus E-P1 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The SX420 has one, while the E-P1 does not. While the built-in flash of the SX420 is not very powerful, it can at times be useful as a fill-in light.
The SX420 writes its imaging data to SDXC cards, while the E-P1 uses SDHC 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 PowerShot SX420 IS and Olympus PEN E-P1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the SX420 offers wifi support, while the E-P1 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the SX420 and the E-P1 have been discontinued, but can regularly be found used on ebay. The E-P1 was replaced by the Olympus E-P2, while the SX420 was followed by the Canon SX430. Further information on the features and operation of the SX420 and E-P1 can be found, respectively, in the Canon SX420 Manual (free pdf) or the online Olympus E-P1 Manual.
So how do things add up? Is there a clear favorite between the Canon SX420 and the Olympus E-P1? Which camera is better? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Canon PowerShot SX420 IS:
- More detail: Offers more megapixels (19.9 vs 12.2MP) with a 28% higher linear resolution.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Ready to shoot: Has a lens built-in, whereas the E-P1 requires a separate lens.
- More compact: Is smaller (104x69mm vs 121x70mm) and thus needs less room in the bag.
- Less heavy: Is lighter even though it comes with a built-in lens (unlike the E-P1).
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More modern: Reflects 6 years and 6 months of technical progress since the E-P1 launch.
Advantages of the Olympus PEN E-P1:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
- Richer colors: The pixel size advantage translates into images with better, more accurate colors.
- More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
- Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
- Better video: Provides higher movie framerates (720/30p versus 720/25p).
- Faster burst: Shoots at higher frequency (3 vs 0.5 flaps/sec) to capture the decisive moment.
- More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
- Longer lasting: Gets more shots (300 versus 195) out of a single battery charge.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- More heavily discounted: Has been around for much longer (launched in June 2009).
If the number of relative strengths (bullet points above) is taken as a guide, the E-P1 comes out slightly ahead of the SX420 (11 : 10 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 SX420 and the Olympus E-P1 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best Mirrorless Interchangeable Lens Camera listings 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the SX420 or the E-P1. 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 review scores listed above should be treated 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
