Olympus E-510 vs Sony RX100 II
The Olympus E-510 and the Sony Cyber-shot DSC-RX100 II are two digital cameras that were revealed to the public, respectively, in March 2007 and June 2013. The E-510 is a DSLR, while the RX100 II is a fixed lens compact. The cameras are based on a Four Thirds (E-510) and an one-inch (RX100 II) sensor. The Olympus has a resolution of 10 megapixels, whereas the Sony provides 20 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 E-510 and the Sony Cyber-shot DSC-RX100 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-510 and the Sony RX100 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 size dimensions are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony RX100 II is considerably smaller (53 percent) than the Olympus E-510. In this context, it is worth noting that neither the E-510 nor the RX100 II are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX100 II has a lens built in, whereas the E-510 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-510 and their specifications in the Four Thirds Lens Catalog.
Concerning battery life, the E-510 gets 750 shots out of its BLM-1 battery, while the RX100 II can take 350 images on a single charge of its NP-BX1 power pack. The power pack in the RX100 II can be charged via the USB port, which can be very convenient when travelling.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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 RX100 II was launched at a lower price than the E-510, 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 Olympus E-510 features a Four Thirds sensor and the Sony RX100 II an one-inch sensor. The sensor area in the RX100 II is 48 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 2.7. The sensor in the E-510 has a native 4:3 aspect ratio, while the one in the RX100 II offers a 3:2 aspect.
Despite having a smaller sensor, the RX100 II offers a higher resolution of 20 megapixels, compared with 10 MP of the E-510. 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 2.41μm versus 4.74μm for the E-510). However, it should be noted that the RX100 II is much more recent (by 6 years and 3 months) than the E-510, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The resolution advantage of the Sony RX100 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX100 II for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inches or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inches or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inches or 46.3 x 30.9 cm. The corresponding values for the Olympus E-510 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-510 has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Sony Cyber-shot DSC-RX100 II are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 100-25600.
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 RX100 II offers substantially better image quality than the E-510 (overall score 15 points higher). The advantage is based on 1.3 bits higher color depth, 2.4 EV in additional dynamic range, and 0.1 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 cannot only take still pictures, but also record videos. The RX100 II indeed provides for movie recording, while the E-510 does not. The highest resolution format that the RX100 II can use is 1080/60p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the E-510 has an optical viewfinder, which can be very useful when shooting in bright sunlight. In contrast, the RX100 II relies on live view and the rear LCD for framing. That said, the RX100 II can be equipped with an optional viewfinder – the FDA-EV1MK. The adjacent table lists some of the other core features of the Olympus E-510 and Sony RX100 II along with similar information for a selection of comparators.

The E-510 writes its imaging data to Compact Flash or xD Picture cards, while the RX100 II uses SDXC or Memory Stick PRO Duo cards. The E-510 features dual card slots, which can be very useful in case a memory card fails. In contrast, the RX100 II only has one slot.
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-510 and Sony Cyber-shot DSC-RX100 II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the RX100 II offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the E-510 does not provide wifi capability.
Both the E-510 and the RX100 II have been discontinued, but can regularly be found used on eBay. The E-510 was replaced by the Olympus E-520, while the RX100 II was followed by the Sony RX100 III. 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 how do things add up? Which of the two cameras – the Olympus E-510 or the Sony RX100 II – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.

If the number of relative strengths (bullet points above) is taken as a guide, the RX100 II is the clear winner of the contest (17 : 6 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.
How about other alternatives? Do the specifications of the Olympus E-510 and the Sony RX100 II place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Travel-Zoom Camera listings 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 says little about, for example, the shooting experience and imaging performance of the E-510 and the RX100 II 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.
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], 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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
