Panasonic G7 versus Panasonic FZ330

The Panasonic Lumix DMC-G7 and the Panasonic Lumix DMC-FZ330 (labelled Panasonic FZ300 in some countries) are two digital cameras that were revealed to the public, respectively, in May 2015 and July 2015. The G7 is a mirrorless interchangeable lens camera, while the FZ330 is a fixed lens compact. The cameras are based on a Four Thirds (G7) and a 1/2.3-inch (FZ330) sensor. The G7 has a resolution of 15.8 megapixel, whereas the FZ330 provides 12 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 G7 vs Panasonic FZ330

The physical size and weight of the Panasonic G7 and the Panasonic FZ330 are illustrated 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 measures 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 G7 – 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 FZ330 is notably larger (13 percent) than the Panasonic G7. It is noteworthy in this context that the FZ330 is splash and dust-proof, while the G7 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the FZ330 has a lens build in, whereas the G7 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can find an overview of optics for the G7 and their specifications in the Micro Four Thirds Lens Catalog.

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 FZ330 was launched at a lower price than the G7, despite having a lens build in. 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 G7 vs Panasonic FZ330

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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Panasonic G7 features a Four Thirds sensor and the Panasonic FZ330 a 1/2.3-inch sensor. The sensor area in the FZ330 is 88 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 5.6. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Panasonic G7 and Panasonic FZ330 sensor measures

With 15.8MP, the G7 offers a higher resolution than the FZ330 (12MP), but the G7 nevertheless has larger individual pixels (pixel pitch of 3.77μm versus 1.53μm for the FZ330) 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 FZ330 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The FZ330 is a current model that online retailers, such as amazon, will have in stock. In contrast, the G7 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the G7 was succeeded by the Panasonic G85.

Review summary: Panasonic G7 vs Panasonic FZ330

So what conclusions can be drawn? Is there a clear favorite between the Panasonic G7 and the Panasonic FZ330? Below is a summary of the relative strengths of each of the two contestants.


Arguments in favor of the Panasonic Lumix DMC-G7:

  • More detail: Offers more megapixels (15.8 vs 12MP) with a 15% higher linear resolution.
  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better low-light imaging: Features bigger pixels on a larger sensor for better high-ISO images.
  • More detailed viewfinder: Has higher resolution electronic viewfinder (2360k vs 1440k dots).
  • More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
  • More compact: Is smaller (125x86mm vs 132x92mm) and thus needs less room in the bag.


Reasons to prefer the Panasonic Lumix DMC-FZ330:

  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Faster burst: Shoots at higher frequency (12 vs 7 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Has an integrated lens, whereas the G7 necessitates an extra lens.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
  • More affordable: Was introduced at a lower price, despite coming with a build-in lens.

If the number of relative strengths (bullet points above) is taken as a guide, the match-up finishes in a tie (6 points each). 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.

G7 06:06 FZ330

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 handling experience and imaging performance when actually working with the G7 or the FZ330. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is where reviews by experts come in. 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).

Care should be taken when interpreting the review scores above, though. The ratings are only valid when refering 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 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.
