Olympus E-420 vs Pentax K-5

The Olympus E-420 and the Pentax K-5 are two digital cameras that were officially introduced, respectively, in March 2008 and September 2010. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a Four Thirds (E-420) and an APS-C (K-5) sensor. The Olympus has a resolution of 10 megapixels, whereas the Pentax provides 16.1 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Olympus E-420 and the Pentax K-5. 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 width, height and depth measures are rounded to the nearest millimeter.

Size Olympus E-420 vs Pentax K-5
Compare E-420 versus K-5 top
Comparison E-420 or K-5 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax K-5 is notably larger (7 percent) than the Olympus E-420. Moreover, the K-5 is substantially heavier (73 percent) than the E-420. It is noteworthy in this context that the K-5 is splash and dust-proof, while the E-420 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the E-420 gets 500 shots out of its Olympus BLS-1 battery, while the K-5 can take 740 images on a single charge of its Pentax D-LI90 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

Note: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

Any camera decision will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The E-420 was launched at a markedly lower price (by 45 percent) than the K-5, 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

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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Olympus E-420 features a Four Thirds sensor and the Pentax K-5 an APS-C sensor. The sensor area in the K-5 is 65 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.5. The sensor in the E-420 has a native 4:3 aspect ratio, while the one in the K-5 offers a 3:2 aspect.

Olympus E-420 and Pentax K-5 sensor measures

With 16.1MP, the K-5 offers a higher resolution than the E-420 (10MP), but the K-5 nevertheless has marginally larger individual pixels (pixel pitch of 4.81μm versus 4.74μm for the E-420) due to its larger sensor. Moreover, the K-5 is a much more recent model (by 2 years and 6 months) than the E-420, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Pentax K-5 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the K-5 for good quality output (200 dots per inch) amounts to 24.6 x 16.3 inches or 62.6 x 41.5 cm, for very good quality (250 dpi) 19.7 x 13.1 inches or 50.1 x 33.2 cm, and for excellent quality (300 dpi) 16.4 x 10.9 inches or 41.7 x 27.6 cm. The corresponding values for the Olympus E-420 are 18.2 x 13.7 inches or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inches or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inches or 30.9 x 23.2 cm for excellent quality prints.

The Olympus E-420 has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Pentax K-5 are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 80-51200.

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.

E-420 versus K-5 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). Of the two cameras under consideration, the K-5 offers substantially better image quality than the E-420 (overall score 26 points higher). The advantage is based on 2.2 bits higher color depth, 3.7 EV in additional dynamic range, and 1.1 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The E-420 and the K-5 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 K-5 offers a wider field of view (100%) than the one in the E-420 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the K-5 has a higher magnification (0.61x vs 0.46x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Olympus E-420 and Pentax K-5 in connection with corresponding information for a sample of similar cameras.

One feature that differentiates the K-5 and the E-420 is in-body image stabilization (IBIS). The K-5 reduces the risk of handshake-induced blur with all attached lenses, while the E-420 offers no blur reduction with lenses that themselves do not provide optical image stabilization.

The Pentax K-5 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

The E-420 writes its imaging data to Compact Flash or xD Picture cards, while the K-5 uses SDXC cards. The E-420 features dual card slots, which can be very useful in case a memory card fails. In contrast, the K-5 only has one slot.

If the count of individual advantages (bullet points above) is taken as a guide, the K-5 is the clear winner of the contest (19 : 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

E-420 04:19 K-5

How about other alternatives? Do the specifications of the Olympus E-420 and the Pentax K-5 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 E-420 and the K-5 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

This is why expert reviews 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 assessments were made in relation to similar cameras of the same technological generation. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
