Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus E-3 and the Pentax K-1? 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: Olympus E-3 vs Pentax K-1
The side-by-side display below illustrates the physical size and weight of the Olympus E-3 and the Pentax K-1. 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 measures are rounded to the nearest millimeter.
The K-1 can be obtained in two different colors (black, silver), while the E-3 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 Pentax K-1 is notably smaller (9 percent) than the Olympus E-3. However, the K-1 is markedly heavier (15 percent) than the E-3. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.
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.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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-3 was somewhat cheaper (by 6 percent) than the K-1 at launch, but both cameras fall into the same price category. 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: Olympus E-3 vs Pentax K-1
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Olympus E-3 features a Four Thirds sensor and the Pentax K-1 a full frame sensor. The sensor area in the K-1 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-3 has a native 4:3 aspect ratio, while the one in the K-1 offers a 3:2 aspect.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
With 36.2MP, the K-1 offers a higher resolution than the E-3 (10MP), but the K-1 nevertheless has larger individual pixels (pixel pitch of 4.88μm versus 4.74μm for the E-3) due to its larger sensor. Moreover, the K-1 is a much more recent model (by 8 years and 4 months) than the E-3, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the K-1 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 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the K-1 for good quality output (200 dots per inch) amounts to 36.8 x 24.6 inch or 93.5 x 62.4 cm, for very good quality (250 dpi) 29.4 x 19.6 inch or 74.8 x 49.9 cm, and for excellent quality (300 dpi) 24.5 x 16.4 inch or 62.3 x 41.6 cm. The corresponding values for the Olympus E-3 are 18.2 x 13.7 inch or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inch or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inch or 30.9 x 23.2 cm for excellent quality prints.
Unlike the E-3, the K-1 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 E-3 has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Pentax K-1 are ISO 100 to ISO 204800 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). Of the two cameras under consideration, the K-1 offers substantially better image quality than the E-3 (overall score 40 points higher). The advantage is based on 3.8 bits higher color depth, 4.1 EV in additional dynamic range, and 2.5 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.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The K-1 indeed provides for movie recording, while the E-3 does not. The highest resolution format that the K-1 can use is 1080/60i.
Feature comparison: Olympus E-3 vs Pentax K-1
Apart from body and sensor, cameras can and do differ across a range of features. The E-3 and the K-1 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 (100%), but the viewfinder of the K-1 has a higher magnification than the one of the E-3 (0.70x vs 0.575x), 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-3 and Pentax K-1 in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The E-3 has one, while the K-1 does not. While the built-in flash of the E-3 is not very powerful, it can at times be useful as a fill-in light.The E-3 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the K-1 does not have a selfie-screen.
The Pentax K-1 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-3 writes its imaging data to Compact Flash or xD Picture cards, while the K-1 uses SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails.
Connectivity comparison: Olympus E-3 vs Pentax K-1
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 E-3 and Pentax K-1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the K-1 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the E-3 does not offer wifi capability.
Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.
Both the E-3 and the K-1 have been discontinued, but can regularly be found used on eBay. The E-3 was replaced by the Olympus E-5, while the K-1 was followed by the Pentax K-1 II. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Olympus and Pentax websites.
Review summary: Olympus E-3 vs Pentax K-1
So what is the bottom line? Which of the two cameras – the Olympus E-3 or the Pentax K-1 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Olympus E-3:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (5 vs 4.4 flaps/sec) to capture the decisive moment.
- Less heavy: Is lighter (by 134g or 13 percent) and hence easier to carry around.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More heavily discounted: Has been available for much longer (launched in October 2007).
Reasons to prefer the Pentax K-1:
- More detail: Has more megapixels (36.2 vs 10MP), which boosts linear resolution by 94%.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- High quality composites: Can combine several shots after pixel-shifting its sensor.
- Better image quality: Scores substantially higher (40 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (3.8 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (4.1 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (2.5 stops ISO advantage).
- Broader imaging potential: Can capture not only stills but also 1080/60i video.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.575x).
- Larger screen: Has a bigger rear LCD (3.2" vs 2.5") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (1037k vs 230k dots).
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- More modern: Reflects 8 years and 4 months of technical progress since the E-3 launch.
If the number of relative strengths (bullet points above) is taken as a guide, the K-1 is the clear winner of the contest (14 : 6 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 Olympus E-3 and the Pentax K-1 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the E-3 and the K-1 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: Olympus E-3 vs Pentax K-1
This is where reviews by experts come in. 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.

|Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (-) not available.|
Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, 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.
