Olympus E-P1 vs Sony RX1R II
The Olympus PEN E-P1 and the Sony Cyber-shot DSC-RX1R II are two enthusiast cameras that were officially introduced, respectively, in June 2009 and October 2015. The E-P1 is a mirrorless interchangeable lens camera, while the RX1R II is a fixed lens compact. The cameras are based on a Four Thirds (E-P1) and a full frame (RX1R II) sensor. The Olympus has a resolution of 12.2 megapixels, whereas the Sony provides 42.2 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 Olympus PEN E-P1 and the Sony Cyber-shot DSC-RX1R 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.
An illustration of the physical size and weight of the Olympus E-P1 and the Sony RX1R II is provided in the side-by-side display below. 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.
The E-P1 can be obtained in three different colors (black, silver, white), while the RX1R II 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 Sony RX1R II is notably smaller (13 percent) than the Olympus E-P1. In this context, it is worth noting that neither the E-P1 nor the RX1R II are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX1R II 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 E-P1 gets 300 shots out of its BLS-1 battery, while the RX1R II can take 220 images on a single charge of its NP-BX1 power pack. The power pack in the RX1R II can be charged via the USB port, which can be very convenient when travelling.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

Any camera decision will obviously take relative prices into account. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. 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 sensor inside a digital camera is one of the key determinants of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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-P1 features a Four Thirds sensor and the Sony RX1R II a full frame sensor. The sensor area in the RX1R II is 280 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-P1 has a native 4:3 aspect ratio, while the one in the RX1R II offers a 3:2 aspect.
With 42.2MP, the RX1R II offers a higher resolution than the E-P1 (12.2MP), but the RX1R II nevertheless has larger individual pixels (pixel pitch of 4.50μm versus 4.29μm for the E-P1) due to its larger sensor. Moreover, the RX1R II is a much more recent model (by 6 years and 3 months) than the E-P1, 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 RX1R II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Sony RX1R II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX1R II for good quality output (200 dots per inch) amounts to 39.8 x 26.5 inches or 101 x 67.4 cm, for very good quality (250 dpi) 31.8 x 21.2 inches or 80.8 x 53.9 cm, and for excellent quality (300 dpi) 26.5 x 17.7 inches or 67.3 x 44.9 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 Olympus PEN E-P1 has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the Sony Cyber-shot DSC-RX1R II are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-102400.
For many cameras, data on sensor performance has been reported by DXO Mark. 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 consideration, the RX1R II offers substantially better image quality than the E-P1 (overall score 42 points higher). The advantage is based on 4.4 bits higher color depth, 3.5 EV in additional dynamic range, and 2.6 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.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the RX1R II provides a better video resolution than the E-P1. It can shoot movie footage at 1080/60p, while the Olympus is limited to 720/30p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the RX1R II has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the E-P1 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Olympus E-P1 and Sony RX1R II in connection with corresponding information for a sample of similar cameras.

|5.||Leica Q Typ 116||3680||n||3.0||1040||fixed||Y||1/2000s||10.0||n||Y|
The E-P1 writes its imaging data to SDHC cards, while the RX1R II uses SDXC or Memory Stick PRO Duo cards. The RX1R II supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the E-P1 cannot take advantage of Ultra High Speed SD 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 Olympus PEN E-P1 and Sony Cyber-shot DSC-RX1R II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the RX1R II offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the E-P1 does not provide wifi capability.
The RX1R II is a recent model that features in the current product line-up of Sony. In contrast, the E-P1 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the E-P1 was succeeded by the Olympus E-P2. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Olympus and Sony websites.
So what conclusions can be drawn? Is the Olympus E-P1 better than the Sony RX1R II or vice versa? The listing below highlights the relative strengths of the two models.

If the number of relative strengths (bullet points above) is taken as a guide, the RX1R II is the clear winner of the contest (19 : 5 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding 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-P1 and the Sony RX1R II place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Prime Lens Compact 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 incomplete and does no justice, for example, to the way the E-P1 or the RX1R II perform in practice. 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 following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
