Body comparison

The physical size and weight of the Olympus E-620 and the Sony RX10 IV are illustrated 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.

Size Olympus E-620 vs Sony RX10 IV
Compare E-620 versus RX10 IV top
Comparison E-620 or RX10 IV rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony RX10 IV is somewhat larger (2 percent) than the Olympus E-620. It is noteworthy in this context that the RX10 IV is splash and dust-proof, while the E-620 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX10 IV has a lens built in, whereas the E-620 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-620 and their specifications in the Four Thirds Lens Catalog.

Concerning battery life, the E-620 gets 500 shots out of its Olympus BLS-1 battery, while the RX10 IV can take 400 images on a single charge of its Sony NP-FW50 power pack. The power pack in the RX10 IV can be charged via the USB port, which can be very convenient when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

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. 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-620 features a Four Thirds sensor and the Sony RX10 IV an one-inch sensor. The sensor area in the RX10 IV 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-620 has a native 4:3 aspect ratio, while the one in the RX10 IV offers a 3:2 aspect.

Olympus E-620 and Sony RX10 IV sensor measures

Despite having a smaller sensor, the RX10 IV offers a higher resolution of 20 megapixels, compared with 12.2 MP of the E-620. 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 4.29μm for the E-620). However, it should be noted that the RX10 IV is much more recent (by 8 years and 6 months) than the E-620, 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 RX10 IV implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX10 IV 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-620 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 RX10 IV has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Olympus E-620 has a native sensitivity range from ISO 100 to ISO 3200. The corresponding ISO settings for the Sony Cyber-shot DSC-RX10 IV are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 64-25600.

In terms of underlying technology, the E-620 is build around a CMOS sensor, while the RX10 IV uses a BSI-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-620 versus RX10 IV MP

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the RX10 IV has an electronic viewfinder (2359k dots), while the E-620 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinder in the RX10 IV offers a wider field of view (100%) than the one in the E-620 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the RX10 IV has a higher magnification (0.70x vs 0.48x), 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-620 and Sony RX10 IV in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The RX10 IV has a touchscreen, while the E-620 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The E-620 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 RX10 IV does not have a selfie-screen.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the RX10 IV is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The E-620 writes its imaging data to Compact Flash or xD Picture cards, while the RX10 IV uses SDXC or Memory Stick PRO Duo cards. The E-620 features dual card slots, which can be very useful in case a memory card fails. In contrast, the RX10 IV only has one slot.

It is notable that the RX10 IV offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the E-620 does not provide wifi capability.

The RX10 IV is a recent model that features in the current product line-up of Sony. In contrast, the E-620 has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the E-620 was succeeded by the Olympus E-600. Further information on the features and operation of the E-620 and RX10 IV can be found, respectively, in the Olympus E-620 Manual (free pdf) or the online Sony RX10 IV Manual.

If the number of relative strengths (bullet points above) is taken as a guide, the RX10 IV is the clear winner of the contest (18 : 8 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-620 08:18 RX10 IV

How about other alternatives? Do the specifications of the Olympus E-620 and the Sony RX10 IV place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Superzoom 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the E-620 or the RX10 IV. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

padding

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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
