Olympus PEN-F vs Panasonic G3

The Olympus PEN-F and the Panasonic Lumix DMC-G3 are two digital cameras that were announced, respectively, in January 2016 and May 2011. Both the PEN-F and the G3 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The Olympus has a resolution of 20.2 megapixels, whereas the Panasonic provides 15.8 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-F and the Panasonic Lumix DMC-G3? 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.

Body comparison: Olympus PEN-F vs Panasonic G3

An illustration of the physical size and weight of the Olympus PEN-F and the Panasonic G3 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 PEN-F can be obtained in two different colors (black, silver), while the G3 is available in four color-versions (black, brown, red, white).

Compare PEN-F versus G3 top
Comparison PEN-F or G3 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic G3 is notably larger (7 percent) than the Olympus PEN-F. However, the G3 is markedly lighter (21 percent) than the PEN-F. In this context, it is worth noting that neither the PEN-F nor the G3 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Micro Four Thirds Lens Catalog. Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.

Concerning battery life, the PEN-F gets 330 shots out of its BLN-1 battery, while the G3 can take 270 images on a single charge of its DMW-BLD10 power pack.

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

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

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. The G3 was launched at a markedly lower price (by 50 percent) than the PEN-F, 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 PEN-F vs Panasonic G3

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 PEN-F and Panasonic G3 sensor measures

While the two cameras under review share the same sensor size, the PEN-F offers a higher resolution of 20.2 megapixels, compared with 15.8 MP of the G3. This megapixels advantage translates into a 13 percent gain in linear resolution. On the other hand, these sensor specs imply that the PEN-F has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.34μm versus 3.77μm for the G3). In this context, it should be noted, however, that the PEN-F is much more recent (by 4 years and 8 months) than the G3, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size. Coming back to sensor resolution, it should be mentioned that the PEN-F has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Olympus PEN-F implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the PEN-F for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inch or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inch or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inch or 43.9 x 32.9 cm. The corresponding values for the Panasonic G3 are 23 x 17.2 inch or 58.3 x 43.8 cm for good quality, 18.4 x 13.8 inch or 46.7 x 35 cm for very good quality, and 15.3 x 11.5 inch or 38.9 x 29.2 cm for excellent quality prints.

Unlike the G3, the PEN-F has the capacity to capture high quality composite images (40MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

The Olympus PEN-F has a native sensitivity range from ISO 80 to ISO 25600. The corresponding ISO settings for the Panasonic Lumix DMC-G3 are ISO 160 to ISO 6400 (no boost).

PEN-F versus G3 MP

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 review, the PEN-F provides substantially higher image quality than the G3, with an overall score that is 18 points higher. This advantage is based on 2.1 bits higher color depth, 1.8 EV in additional dynamic range, and 0.4 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 PEN-F provides a higher frame rate than the G3. It can shoot video footage at 1080/60p, while the Panasonic is limited to 1080/60i.

 

Feature comparison: Olympus PEN-F vs Panasonic G3

Apart from body and sensor, cameras can and do differ across a range of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the PEN-F offers a substantially higher resolution than the one in the G3 (2360k vs 1440k dots).

One feature that differentiates the PEN-F and the G3 is in-body image stabilization (IBIS). The PEN-F reduces the risk of handshake-induced blur with all attached lenses, while the G3 has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.

Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.

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 PEN-F 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 Olympus PEN-F 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.

Concerning the storage of imaging data, both the PEN-F and the G3 write their files to SDXC cards. The PEN-F supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the G3 cannot take advantage of Ultra High Speed SD cards.

 

Connectivity comparison: Olympus PEN-F vs Panasonic G3

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-F and Panasonic Lumix DMC-G3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the PEN-F offers wifi support, while the G3 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

The PEN-F is a recent model that features in the current product line-up of Olympus. In contrast, the G3 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the G3 was succeeded by the Panasonic G5. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Olympus and Panasonic websites.


Review summary: Olympus PEN-F vs Panasonic G3

So what conclusions can be drawn? Is the Olympus PEN-F better than the Panasonic G3 or vice versa? The listing below highlights the relative strengths of the two models.

ilogo

Advantages of the Olympus PEN-F:

  • More detail: Offers more megapixels (20.2 vs 15.8MP) with a 13% higher linear resolution.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • Better image quality: Scores substantially higher (18 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (2.1 bits more color depth).
  • More dynamic range: Captures a larger spectrum of light and dark details (1.8 EV of extra DR).
  • Better low-light sensitivity: Requires less light for good images (0.4 stops ISO advantage).
  • Better video: Provides higher movie framerates (1080/60p versus 1080/60i).
  • More detailed viewfinder: Has higher resolution electronic viewfinder (2360k vs 1440k dots).
  • More detailed LCD: Has a higher resolution rear screen (1037k vs 460k dots).
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (10 vs 4 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.
  • Longer lasting: Can take more shots (330 versus 270) on a single battery charge.
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Faster buffer clearing: Supports Ultra High Speed (UHS-II) SDXC cards.
  • More modern: Reflects 4 years and 8 months of technical progress since the G3 launch.

ilogo

Reasons to prefer the Panasonic Lumix DMC-G3:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.62x).
  • Less heavy: Has a lower weight (by 91g or 21 percent) and is thus easier to take along.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (50 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in May 2011).

If the number of relative strengths (bullet points above) is taken as a guide, the PEN-F is the clear winner of the match-up (19 : 6 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 PEN-F and the Panasonic G3 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing 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 PEN-F or the G3 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: Olympus PEN-F vs Panasonic G3

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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.
