Panasonic GX850 versus Fujifilm X70

The Panasonic Lumix DMC-GX850 (called Panasonic GX800 in some regions) and the Fujifilm X70 are two digital cameras that were announced, respectively, in January 2017 and January 2016. The GX850 is a mirrorless interchangeable lens camera, while the X70 is a fixed lens compact. The cameras are based on a Four Thirds (GX850) and an APS-C (X70) sensor. The Panasonic has a resolution of 15.8 megapixel, whereas the Fujifilm provides 16 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 GX850 vs Fujifilm X70

An illustration of the physical size and weight of the Panasonic GX850 and the Fujifilm X70 is provided in the side-by-side display below. 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. 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 – the GX850 – represents the basis or 100 percent 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 Fujifilm X70 is somewhat larger (4 percent) than the Panasonic GX850. In this context, it is worth noting that neither the GX850 nor the X70 are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the X70 has a lens build in, whereas the GX850 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 GX850 and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the GX850 gets 210 shots out of its DMW-BLH7 battery, while the X70 can take 330 images on a single charge of its NP-95 power pack.

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. 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 GX850 vs Fujifilm X70

The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Panasonic GX850 features a Four Thirds sensor and the Fujifilm X70 an APS-C sensor. The sensor area in the X70 is 64 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.5. The sensor in the GX850 has a native 4:3 aspect ratio, while the one in the X70 offers a 3:2 aspect.

Panasonic GX850 and Fujifilm X70 sensor measures

With 16MP, the X70 offers a higher resolution than the GX850 (15.8MP), but the X70 nevertheless has larger individual pixels (pixel pitch of 4.80μm versus 3.77μm for the GX850) due to its larger sensor. However, the GX850 is a somewhat more recent model (by 11 months) than the X70, 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

GX850 versus X70 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). 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 cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the GX850 provides a higher video resolution than the X70. It can shoot video footage at 4K/30p, while the Fujifilm is limited to 1080/60p.

 

Feature comparison: Panasonic GX850 vs Fujifilm X70

Apart from body and sensor, cameras can and do differ across a range of features. The GX850 and the X70 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. The table below summarizes some of the other core capabilities of the Panasonic GX850 and Fujifilm X70 in connection with corresponding information for a sample of similar cameras.

Both the GX850 and the X70 are current models that good online retailers will have in stock. You can check the latest prices, for example, at amazon. The GX850 replaced the earlier Panasonic GF7, while the X70 does not have a direct predecessor.

Review summary: Panasonic GX850 vs Fujifilm X70

So what conclusions can be drawn? Which of the two cameras – the Panasonic GX850 or the Fujifilm X70 – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Reasons to prefer the Panasonic Lumix DMC-GX850:

  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • Faster burst: Shoots at higher frequency (10 vs 8 flaps/sec) to capture the decisive moment.
  • More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
  • More modern: Is somewhat more recent (announced 11 months after the X70).

ilogo

Advantages of the Fujifilm X70:

  • Better low-light imaging: Features bigger pixels on a larger sensor for better high-ISO images.
  • Faster shutter: Has higher mechanical shutter speed (4000/sec vs 500/sec) to freeze action.
  • Ready to shoot: Has an integrated lens, whereas the GX850 necessitates an extra lens.
  • Longer lasting: Gets more shots (330 versus 210) out of a single battery charge.
  • More heavily discounted: Has been on the market for longer (launched in January 2016).

If the count of relative strengths (bullet points above) is taken as a measure, the X70 comes out slightly ahead of the GX850 (5 : 4 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.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the GX850 or the X70. 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 above review scores should be interpreted with care, though. The ratings are only valid when refering to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
