Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus Evolt E-300 and the Pentax K-1 II? 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

An illustration of the physical size and weight of the Olympus E-300 and the Pentax K-1 II 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 K-1 II can be obtained in two different colors (black, silver), while the E-300 is only available in black.

Compare E-300 versus K-1 II top
Comparison E-300 or K-1 II rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax K-1 II is notably larger (21 percent) than the Olympus E-300. Moreover, the K-1 II is substantially heavier (62 percent) than the E-300. It is noteworthy in this context that the K-1 II is splash and dust-proof, while the E-300 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-300 gets 750 shots out of its BLM-1 battery, while the K-1 II can take 670 images on a single charge of its D-LI90 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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

Any camera decision will obviously take relative prices into account. 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-300 was launched at a markedly lower price (by 60 percent) than the K-1 II, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 sensor inside a digital camera is one of the key determinants 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Olympus E-300 features a Four Thirds sensor and the Pentax K-1 II a full frame sensor. The sensor area in the K-1 II is 283 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.0. The sensor in the E-300 has a native 4:3 aspect ratio, while the one in the K-1 II offers a 3:2 aspect.

Olympus E-300 and Pentax K-1 II sensor measures

With 36.2MP, the K-1 II offers a higher resolution than the E-300 (8MP), but the K-1 II has smaller individual pixels (pixel pitch of 4.88μm versus 5.30μm for the E-300). Yet, the K-1 II is a much more recent model (by 13 years and 4 months) than the E-300, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the K-1 II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Pentax K-1 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the K-1 II for good quality output (200 dots per inch) amounts to 36.8 x 24.6 inches or 93.5 x 62.4 cm, for very good quality (250 dpi) 29.4 x 19.6 inches or 74.8 x 49.9 cm, and for excellent quality (300 dpi) 24.5 x 16.4 inches or 62.3 x 41.6 cm. The corresponding values for the Olympus E-300 are 16.3 x 12.2 inches or 41.5 x 31.1 cm for good quality, 13.1 x 9.8 inches or 33.2 x 24.9 cm for very good quality, and 10.9 x 8.2 inches or 27.6 x 20.7 cm for excellent quality prints.

Unlike the E-300, the K-1 II has the capacity to capture high quality composite images by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

The Olympus Evolt E-300 has a native sensitivity range from ISO 100 to ISO 400, which can be extended to ISO 100-1600. The corresponding ISO settings for the Pentax K-1 II are ISO 100 to ISO 819200 (no boost).

In terms of underlying technology, the E-300 is build around a CCD sensor, while the K-1 II 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.

E-300 versus K-1 II MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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. The K-1 II indeed provides for movie recording, while the E-300 does not. The highest resolution format that the K-1 II can use is 1080/60i.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The E-300 and the K-1 II 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-1 II offers a wider field of view (100%) than the one in the E-300 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the K-1 II has a higher magnification (0.70x vs 0.5x), 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 Olympus E-300 and Pentax K-1 II along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The E-300 has one, while the K-1 II does not. While the built-in flash of the E-300 is not very powerful, it can at times be useful as a fill-in light.

The Pentax K-1 II 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-300 writes its imaging data to Compact Flash or xD Picture cards, while the K-1 II uses SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails.

Connectivity comparison

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 Olympus Evolt E-300 and Pentax K-1 II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the K-1 II offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the E-300 does not provide wifi capability.

Studio photographers will appreciate that the Pentax K-1 II (unlike the E-300) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Travel and landscape photographers will find it useful that the K-1 II has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

The K-1 II is a recent model that features in the current product line-up of Pentax. In contrast, the E-300 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the E-300 was succeeded by the Olympus E-330. Further information on the features and operation of the E-300 and K-1 II can be found, respectively, in the Olympus E-300 Manual (free pdf) or the online Pentax K-1 II Manual.

Review summary

So what conclusions can be drawn? Is the Olympus E-300 better than the Pentax K-1 II or vice versa? The listing below highlights the relative strengths of the two models.

ilogo

Arguments in favor of the Olympus Evolt E-300:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • More compact: Is smaller (147x85mm vs 137x110mm) and thus needs less room in the bag.

If the count of relative strengths (bullet points above) is taken as a measure, the K-1 II is the clear winner of the contest (23 : 7 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. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

E-300 07:23 K-1 II

How about other alternatives? Do the specifications of the Olympus E-300 and the Pentax K-1 II 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the E-300 or the K-1 II. 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 following table reports the overall ratings of the cameras as published by some of the major 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

Care should be taken when interpreting the review scores above, 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 comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
