Panasonic FZ300 versus Canon G3 X

The Panasonic Lumix DMC-FZ300 (called Panasonic FZ330 in some regions) and the Canon PowerShot G3 X are two digital cameras that were revealed to the public, respectively, in July 2015 and June 2015. Both the FZ300 and the G3X are fixed lens compact cameras that are based on a 1/2.3-inch (FZ300) and an one-inch (G3X) sensor. The Panasonic has a resolution of 12 megapixel, whereas the Canon provides 20 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 G3 X

An illustration of the physical size and weight of the Panasonic FZ300 and the Canon G3 X is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions 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 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 G3 X is notably smaller (22 percent) than the Panasonic FZ300. However, the G3X is markedly heavier (6 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 G3X can take 300 images on a single charge of its NB-10L power pack.

The camera’s price is obviously a critical decision-making factor. 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 40 percent) than the G3X, 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 G3 X

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 Panasonic FZ300 features a 1/2.3-inch sensor and the Canon G3 X an one-inch sensor. The sensor area in the G3X is 314 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 2.7. The sensor in the FZ300 has a native 4:3 aspect ratio, while the one in the G3X offers a 3:2 aspect.

In terms of underlying technology, both cameras are build around BSI-CMOS sensors.

Panasonic FZ300 and Canon G3 X sensor measures

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.

FZ300 versus G3X MP

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 G3X offers substantially better image quality than the FZ300 (overall score 25 points higher). The 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 adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the FZ300 provides a higher video resolution than the G3X. It can shoot video footage at 4K/30p, while the Canon is limited to 1080/60p.

 

Feature comparison: Panasonic FZ300 vs Canon G3 X

Beyond body and sensor, cameras can and do differ across a range 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 table below summarizes some of the other core capabilities of the Panasonic FZ300 and Canon G3 X in connection with corresponding information for a sample of similar cameras.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the FZ300 features an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (rolling shutter) or shooting under artificial light sources (flickering).

Both the FZ300 and the G3X have zoom lenses build in. The FZ300 has a 25-600mm f/2.8-2.8 optic and the G3X offers a 24-600mm 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 and the same tele-photo reach at the long end. Both cameras offer the same maximum aperture.

Both the FZ300 and the G3X write their imaging data to SDXC cards.

FZ300 09:12 G3X

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the FZ300 and the G3X in practical situations. 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).

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
