Panasonic FZ300 versus Canon G1 X Mark III

The Panasonic Lumix DMC-FZ300 (called Panasonic FZ330 in some regions) and the Canon PowerShot G1 X Mark III are two digital cameras that were announced, respectively, in July 2015 and October 2017. Both the FZ300 and the G1X Mark III are fixed lens compact cameras that are based on a 1/2.3-inch (FZ300) and an APS-C (G1X Mark III) sensor. The Panasonic has a resolution of 12 megapixel, whereas the Canon provides 24 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: Panasonic FZ300 vs Canon G1 X Mark III

An illustration of the physical size and weight of the Panasonic FZ300 and the Canon G1 X Mark III is provided in the side-by-side display below. Three successive views from the front, the top, and the rear are shown. All width, height and depth dimensions are rounded to the nearest millimeter. You can also toggle the display to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left side – the FZ300 – 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 Canon G1 X Mark III is notably smaller (26 percent) than the Panasonic FZ300. Moreover, the G1X Mark III is substantially lighter (42 percent) than the FZ300. 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.

Concerning battery life, the FZ300 gets 380 shots out of its DMW-BLC12 battery, while the G1X Mark III can take 200 images on a single charge of its NB-13L power pack.

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 FZ300 was launched at a markedly lower price (by 54 percent) than the G1X Mark III, 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: Panasonic FZ300 vs Canon G1 X Mark III

The size of the imaging sensor is a crucial determinant 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. 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 Panasonic FZ300 features a 1/2.3-inch sensor and the Canon G1 X Mark III an APS-C sensor. The sensor area in the G1X Mark III is 1086 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 1.5. The sensor in the FZ300 has a native 4:3 aspect ratio, while the one in the G1X Mark III offers a 3:2 aspect.

Panasonic FZ300 and Canon G1 X Mark III sensor measures

With 24MP, the G1X Mark III offers a higher resolution than the FZ300 (12MP), but the G1X Mark III nevertheless has larger individual pixels (pixel pitch of 3.72μm versus 1.53μm for the FZ300) due to its larger sensor. Moreover, the G1X Mark III is a much more recent model (by 2 years and 3 months) than the FZ300, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. 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.

Both the FZ300 and the G1X Mark III have zoom lenses build in. The FZ300 has a 25-600mm f/2.8-2.8 optic and the G1X Mark III offers a 24-72mm f/2.8-5.6 (focal lengths in full frame equivalent terms). Hence, the Canon provides a wider angle of view at the short end than the Panasonic, but less tele-photo reach at the long end. Both cameras offer the same maximum aperture.

Both the FZ300 and the G1X Mark III are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The FZ300 replaced the earlier Panasonic FZ200, while the G1X Mark III followed on from the Canon G1 X Mark II.

Review summary: Panasonic FZ300 vs Canon G1 X Mark III

So what conclusions can be drawn? Which of the two cameras – the Panasonic FZ300 or the Canon G1 X Mark III – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Arguments in favor of the Panasonic Lumix DMC-FZ300:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • Faster shutter: Has higher mechanical shutter speed (4000/sec vs 2000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (12 vs 9 flaps/sec) to capture the decisive moment.
  • More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
  • Longer lasting: Can take more shots (380 versus 200) on a single battery charge.
  • More affordable: Was introduced into a lower priced category (54 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in July 2015).

ilogo

Reasons to prefer the Canon PowerShot G1 X Mark III:

  • More detail: Has more megapixels (24 vs 12MP), which boosts linear resolution by 44%.
  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better image quality: Is equipped with a larger and more technologically advanced sensor.
  • More detailed viewfinder: Has higher resolution electronic viewfinder (2360k vs 1440k dots).
  • Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
  • More compact: Is smaller (115x78mm vs 132x92mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 292g or 42 percent) and is thus easier to take along.
  • More modern: Reflects 2 years and 3 months of technical progress since the FZ300 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the match-up finishes in a tie (8 points each). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera.

FZ300 08:08 G1X Mark III

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 FZ300 or the G1X Mark III 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 following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, 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.
