Olympus E-30 versus Panasonic G5
The Olympus E-30 and the Panasonic Lumix DMC-G5 are two digital cameras that were revealed to the public, respectively, in November 2008 and July 2012. The E-30 is a DSLR, while the G5 is a mirrorless interchangeable lens camera. Both cameras are equipped with a Four Thirds sensor. The Olympus has a resolution of 12.2 megapixel, whereas the Panasonic provides 15.9 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.
Body comparison: Olympus E-30 vs Panasonic G5
The side-by-side display below illustrates the physical size and weight of the Olympus E-30 and the Panasonic G5. Three consecutive views from the front, the top, and the rear side are shown. All width, height and depth dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left side – the E-30 – represents the basis for the calculations across all the size and weight measures).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic G5 is considerably smaller (35 percent) than the Olympus E-30. Moreover, the G5 is substantially lighter (44 percent) than the E-30. In this context, it is worth noting that neither the E-30 nor the G5 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 find an overview of optics for the two cameras in the Four Thirds Lens Catalog (E-30) and the Micro Four Thirds Lens Catalog (G5). Mirrorless cameras, such as the G5, 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.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G5 was launched at a markedly lower price (by 54 percent) than the E-30, which puts it into a different market segment. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
Sensor comparison: Olympus E-30 vs Panasonic G5
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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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.
While the two cameras under review share the same sensor size, the G5 offers a higher resolution of 15.9 megapixel, compared with 12.2 MP of the E-30. This megapixel advantage translates into a 14 percent gain in linear resolution. On the other hand, these sensor specs imply that the G5 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.76μm versus 4.29μm for the E-30). However, it should be noted that the G5 is much more recent (by 3 years and 8 months) than the E-30, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras cannot only take still pictures, but also record videos. The G5 indeed provides for movie recording, while the E-30 does not. The highest resolution format that the G5 can use is 1080/60p.
Feature comparison: Olympus E-30 vs Panasonic G5
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G5 has an electronic viewfinder (1440k dots), while the E-30 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 following table reports on some other key feature differences and similarities of the Olympus E-30, the Panasonic G5, and comparable cameras.

- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- Faster burst: Shoots at higher frequency (6 vs 5 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (120x83mm vs 142x108mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 305g or 44 percent) and is thus easier to take along.
- More legacy lens friendly: Can use many non-native lenses via adapters.
- More affordable: Was introduced into a lower priced category (54 percent cheaper at launch).
- More modern: Reflects 3 years and 8 months of technical progress since the E-30 launch.
If the count of individual advantages (bullet points above) is taken as a guide, the G5 is the clear winner of the contest (12 : 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.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the E-30 or the G5 handle or 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 expert reviews are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
