Canon G3 X vs Panasonic FZ300
The Canon PowerShot G3 X and the Panasonic Lumix DMC-FZ300 (labelled Panasonic FZ330 in some countries) are two digital cameras that were announced, respectively, in June 2015 and July 2015. Both the G3X and the FZ300 are fixed lens compact cameras that are based on an one-inch (G3X) and a 1/2.3-inch (FZ300) sensor. The Canon has a resolution of 20 megapixels, whereas the Panasonic provides 12 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 Canon PowerShot G3 X and the Panasonic Lumix DMC-FZ300? 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.
The side-by-side display below illustrates the physical size and weight of the Canon G3 X and the Panasonic FZ300. 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic FZ300 is notably larger (28 percent) than the Canon G3 X. However, the FZ300 is markedly lighter (6 percent) than the G3X. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.
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 FZ300 was launched at a markedly lower price (by 40 percent) than the G3X, which puts it into a different market segment. 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.
The size of the sensor inside a digital camera is one of the key determinants 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.
Of the two cameras under consideration, the Canon G3 X features an one-inch sensor and the Panasonic FZ300 a 1/2.3-inch sensor. The sensor area in the FZ300 is 76 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 5.6. The sensor in the G3X has a native 3:2 aspect ratio, while the one in the FZ300 offers a 4:3 aspect.
With 20MP, the G3X offers a higher resolution than the FZ300 (12MP), but the G3X nevertheless has larger individual pixels (pixel pitch of 2.41μm versus 1.53μm for the FZ300) due to its larger sensor. It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation. Coming back to sensor resolution, it should be mentioned that the FZ300 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Canon G3 X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G3X 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 Panasonic FZ300 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.
The Canon PowerShot G3 X has a native sensitivity range from ISO 125 to ISO 12800, which can be extended to ISO 125-25600. The corresponding ISO settings for the Panasonic Lumix DMC-FZ300 are ISO 100 to ISO 6400 (no boost).
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"). Of the two cameras under review, the G3X provides substantially higher image quality than the FZ300, with an overall score that is 25 points higher. This advantage is based on 2.1 bits higher color depth, 1.3 EV in additional dynamic range, and 2.4 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 cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the FZ300 provides a better video resolution than the G3X. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/60p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the FZ300 has an electronic viewfinder (1440k dots), which can be very helpful when shooting in bright sunlight. In contrast, the G3X relies on live view and the rear LCD for framing. That said, the G3X can be equipped with an optional viewfinder – the EVF-DC1. The following table reports on some other key feature differences and similarities of the Canon G3 X, the Panasonic FZ300, and comparable cameras.

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 FZ300 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 FZ300 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.
Both the G3X and the FZ300 have zoom lenses built in. The G3X has a 24-600mm f/2.8-5.6 optic and the FZ300 offers a 25-600mm f/2.8-2.8 (focal lengths in full frame equivalent terms). Hence, the Canon provides a wider angle of view at the short end than the Panasonic and the same tele-photo reach at the long end. Both cameras offer the same maximum aperture.
Concerning the storage of imaging data, both the G3X and the FZ300 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
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 Canon PowerShot G3 X and Panasonic Lumix DMC-FZ300 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the G3X and the FZ300 are recent models that are part of the current product line-up. The FZ300 replaced the earlier Panasonic FZ200, while the G3X does not have a direct predecessor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Panasonic websites.
So what is the bottom line? Is the Canon G3 X better than the Panasonic FZ300 or vice versa? Below is a summary of the relative strengths of each of the two contestants.
Arguments in favor of the Canon PowerShot G3 X:
- More detail: Offers more megapixels (20 vs 12MP) with a 32% higher linear resolution.
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better image quality: Scores substantially higher (25 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 (1.3 EV of extra DR).
- Better low-light sensitivity: Requires less light for good images (2.4 stops ISO advantage).
- Better sound control: Has a headphone port that enables audio monitoring while recording.
- Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (1620k vs 1040k dots).
- Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
- More compact: Is smaller (123x77mm vs 132x92mm) and thus needs less room in the bag.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
Reasons to prefer the Panasonic Lumix DMC-FZ300:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.

- Easier framing: Has an electronic viewfinder for image composition and settings control.
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Faster shutter: Has higher mechanical shutter speed (1/4000s vs 1/2000s) to freeze action.
- Faster burst: Shoots at higher frequency (12 vs 5.9 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: Gets more shots (380 versus 300) out of a single battery charge.
- More affordable: Was introduced into a lower priced category (40 percent cheaper at launch).
If the number of relative strengths (bullet points above) is taken as a guide, the G3X emerges as the winner of the contest (12 : 10 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.
How about other alternatives? Do the specifications of the Canon G3 X and the Panasonic FZ300 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera listing 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 G3X or the FZ300 perform in practice. 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.
This is why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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. 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.
