Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus Stylus 1 and the Panasonic Lumix DMC-GH3? 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
The physical size and weight of the Olympus Stylus 1 and the Panasonic GH3 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures 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 Panasonic GH3 is notably larger (23 percent) than the Olympus Stylus 1. It is noteworthy in this context that the GH3 is splash and dust-proof, while the Stylus 1 does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the Stylus 1 has a lens built in, whereas the GH3 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 GH3 and their specifications in the Micro Four Thirds Lens Catalog.
Concerning battery life, the Stylus 1 gets 410 shots out of its Olympus BLS-5 battery, while the GH3 can take 540 images on a single charge of its Panasonic DMW-BLF19 power pack.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

The price is, of course, an important factor in any camera decision. 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 Stylus 1 was launched at a lower price than the GH3, despite having a lens built in. 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.
Sensor comparison
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 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. 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Olympus Stylus 1 features a 1/1.7-inch sensor and the Panasonic GH3 a Four Thirds sensor. The sensor area in the GH3 is 423 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.5 and 2.0. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

With 15.9MP, the GH3 offers a higher resolution than the Stylus 1 (11.8MP), but the GH3 nevertheless has larger individual pixels (pixel pitch of 3.76μm versus 1.91μm for the Stylus 1) due to its larger sensor. However, the Stylus 1 is a somewhat more recent model (by 1 year and 1 month) than the GH3, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the Stylus 1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Panasonic GH3 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the GH3 for good quality output (200 dots per inch) amounts to 23 x 17.3 inches or 58.5 x 43.9 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.8 x 35.1 cm, and for excellent quality (300 dpi) 15.4 x 11.5 inches or 39 x 29.3 cm. The corresponding values for the Olympus Stylus 1 are 19.8 x 14.9 inches or 50.4 x 37.8 cm for good quality, 15.9 x 11.9 inches or 40.3 x 30.2 cm for very good quality, and 13.2 x 9.9 inches or 33.6 x 25.2 cm for excellent quality prints.
The Olympus Stylus 1 has a native sensitivity range from ISO 100 to ISO 12800. The corresponding ISO settings for the Panasonic Lumix DMC-GH3 are ISO 200 to ISO 12800, with the possibility to increase the ISO range to 125-25600.
In terms of underlying technology, the Stylus 1 is build around a BSI-CMOS sensor, while the GH3 uses a 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.

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. Of the two cameras under consideration, the GH3 offers substantially better image quality than the Stylus 1 (overall score 20 points higher). The advantage is based on 2 bits higher color depth, 0.8 EV in additional dynamic range, and 2.2 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

| Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one. | |||||||||||
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 GH3 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 Stylus 1 and the Panasonic GH3 both have 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 Stylus 1 and the GH3 write their files to SDXC cards. The GH3 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the Stylus 1 cannot take advantage of Ultra High Speed SD cards.
Connectivity comparison
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 Stylus 1 and Panasonic Lumix DMC-GH3 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the GH3 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The Stylus 1 does not feature such a mic input.
Studio photographers will appreciate that the Panasonic GH3 (unlike the Stylus 1) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the Stylus 1 and the GH3 have been discontinued, but can regularly be found used on ebay. The GH3 was replaced by the Panasonic GH4, while the Stylus 1 was followed by the Olympus Stylus 1s. Further information on the features and operation of the Stylus 1 and GH3 can be found, respectively, in the Olympus Stylus 1 Manual (free pdf) or the online Panasonic GH3 Manual.
Review summary
So what conclusions can be drawn? Is the Olympus Stylus 1 better than the Panasonic GH3 or vice versa? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Olympus Stylus 1:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- More detailed LCD: Has a higher resolution rear screen (1040k vs 614k dots).
- Faster burst: Shoots at higher frequency (7 vs 6 flaps/sec) to capture the decisive moment.
- Ready to shoot: Has a lens built-in, whereas the GH3 requires a separate lens.
- More compact: Is smaller (116x87mm vs 133x93mm) and thus needs less room in the bag.
- Less heavy: Is lighter even though it comes with a built-in lens (unlike the GH3).
- Sharper images: Has hand-shake reducing image stabilization built-in.
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More modern: Is somewhat more recent (announced 1 year and 1 month after the GH3).

Advantages of the Panasonic Lumix DMC-GH3:
- More detail: Has more megapixels (15.9 vs 11.8MP), which boosts linear resolution by 16%.
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better image quality: Scores substantially higher (20 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (2 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (0.8 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (2.2 stops ISO advantage).
- Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
- Better sound: Can connect to an external microphone for higher quality sound recording.
- Better sound control: Has a headphone port that enables audio monitoring while recording.
- More detailed viewfinder: Has higher resolution electronic viewfinder (1746k vs 1440k dots).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.67x vs 0.58x).
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
- Less disturbing: Has an electronic shutter option for completely silent shooting.
- More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
- Longer lasting: Gets more shots (540 versus 410) out of a single battery charge.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More heavily discounted: Has been on the market for longer (launched in September 2012).
If the count of individual advantages (bullet points above) is taken as a guide, the GH3 is the clear winner of the contest (21 : 9 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 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 Stylus 1 and the Panasonic GH3 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the Stylus 1 or the GH3. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.
Expert reviews
This is why hands-on reviews by experts 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.

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
