Body comparison

The physical size and weight of the Olympus E-520 and the Panasonic G7 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter.

The G7 can be obtained in two different colors (black, silver), while the E-520 is only available in black.

Size Olympus E-520 vs Panasonic G7
Compare E-520 versus G7 top
Comparison E-520 or G7 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic G7 is notably smaller (14 percent) than the Olympus E-520. Moreover, the G7 is markedly lighter (23 percent) than the E-520. In this context, it is worth noting that neither the E-520 nor the G7 are weather-sealed.

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. Both cameras have similarly sized sensors, but DSLRs have a larger flange-to-focal plane distance than mirrorless cameras, which imposes contraints on the optical engineering process and generally leads to bigger and heavier lenses. You can compare the optics available for the two cameras in the Four Thirds Lens Catalog (E-520) and the Micro Four Thirds Lens Catalog (G7). Mirrorless cameras, such as the G7, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.

Concerning battery life, the E-520 gets 750 shots out of its Olympus BLM-1 battery, while the G7 can take 350 images on a single charge of its Panasonic DMW-BLC12 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G7 was somewhat cheaper (by 7 percent) than the E-520 at launch, but both cameras fall into the same price category. 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 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.

Both cameras under consideration feature a Four Thirds sensor and have a format factor (sometimes also referred to as "crop factor") of 2.0. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Olympus E-520 and Panasonic G7 sensor measures

While the two cameras under review share the same sensor size, the G7 offers a higher resolution of 15.8 megapixels, compared with 10 MP of the E-520. This megapixels advantage translates into a 26 percent gain in linear resolution. On the other hand, these sensor specs imply that the G7 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.77μm versus 4.74μm for the E-520). However, it should be noted that the G7 is much more recent (by 7 years) than the E-520, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.

The resolution advantage of the Panasonic G7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G7 for good quality output (200 dots per inch) amounts to 23 x 17.2 inches or 58.3 x 43.8 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.7 x 35 cm, and for excellent quality (300 dpi) 15.3 x 11.5 inches or 38.9 x 29.2 cm. The corresponding values for the Olympus E-520 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-520 has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Panasonic Lumix DMC-G7 are ISO 160 to ISO 25600 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. 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-520 versus G7 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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").

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G7 has an electronic viewfinder (2360k dots), while the E-520 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 G7 offers a wider field of view (100%) than the one in the E-520 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the G7 has a higher magnification (0.70x vs 0.46x), 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-520 and Panasonic G7 along with similar information for a selection of comparators.

One feature that differentiates the E-520 and the G7 is in-body image stabilization (IBIS). The E-520 reduces the risk of handshake-induced blur with all attached lenses, while the G7 offers no blur reduction with lenses that themselves do not provide optical image stabilization.

The G7 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the E-520 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 G7 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 Panasonic G7 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-520 writes its imaging data to Compact Flash or xD Picture cards, while the G7 uses SDXC cards. The E-520 features dual card slots, which can be very useful in case a memory card fails. In contrast, the G7 only has one slot.

It is notable that the G7 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the E-520 does not provide wifi capability.

Both the E-520 and the G7 have been discontinued, but can regularly be found used on ebay. The G7 was replaced by the Panasonic G85, while the E-520 does not have a direct successor. Further information on the features and operation of the E-520 and G7 can be found, respectively, in the Olympus E-520 Manual (free pdf) or the online Panasonic G7 Manual.

  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More heavily discounted: Has been available for much longer (launched in May 2008).

ilogo

Advantages of the Panasonic Lumix DMC-G7:

  • More detail: Has more megapixels (15.8 vs 10MP), which boosts linear resolution by 26%.
  • Broader imaging potential: Can capture not only stills but also 4K/30p video.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.46x).
  • Larger screen: Has a bigger rear LCD (3.0" vs 2.7") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 215k dots).
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (7 vs 3.5 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More compact: Is smaller (125x86mm vs 136x92mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 125g or 23 percent) and is thus easier to take along.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • More modern: Reflects 7 years of technical progress since the E-520 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the G7 is the clear winner of the contest (18 : 5 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 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.

E-520 05:18 G7

How about other alternatives? Do the specifications of the Olympus E-520 and the Panasonic G7 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens 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 incomplete and does no justice, for example, to the way the E-520 or the G7 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.

Expert reviews

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], 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.

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