Panasonic G9 versus Fujifilm X-T20

The Panasonic Lumix DC-G9 and the Fujifilm X-T20 are two digital cameras that were announced, respectively, in November 2017 and January 2017. Both the G9 and the X-T20 are mirrorless interchangeable lens cameras that are based on a Four Thirds (G9) and an APS-C (X-T20) sensor. The Panasonic has a resolution of 20.2 megapixel, whereas the Fujifilm 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 G9 vs Fujifilm X-T20

An illustration of the physical size and weight of the Panasonic G9 and the Fujifilm X-T20 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 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 G9 – represents 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 X-T20 is notably smaller (26 percent) than the Panasonic G9. Moreover, the X-T20 is substantially lighter (42 percent) than the G9. It is worth mentioning in this context that the G9 is splash and dust resistant, while the X-T20 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can find an overview of optics for the two cameras in the Micro Four Thirds Lens Catalog (G9) and the Fujinon X Lens Catalog (X-T20). Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.

Concerning battery life, the G9 gets 400 shots out of its DMW-BLF19 battery, while the X-T20 can take 350 images on a single charge of its NP-W126S power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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 X-T20 was launched at a markedly lower price (by 47 percent) than the G9, 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 G9 vs Fujifilm X-T20

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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Panasonic G9 features a Four Thirds sensor and the Fujifilm X-T20 an APS-C sensor. The sensor area in the X-T20 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 G9 has a native 4:3 aspect ratio, while the one in the X-T20 offers a 3:2 aspect.

Panasonic G9 and Fujifilm X-T20 sensor measures

With 24MP, the X-T20 offers a higher resolution than the G9 (20.2MP), but the X-T20 nevertheless has larger individual pixels (pixel pitch of 3.92μm versus 3.34μm for the G9) due to its larger sensor. However, the G9 is a somewhat more recent model (by 9 months) than the X-T20, 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.

Unlike the X-T20, the G9 has the capacity to capture high quality composite images (80.6MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

G9 versus X-T20 MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait").

Review summary: Panasonic G9 vs Fujifilm X-T20

So how do things add up? Which of the two cameras – the Panasonic G9 or the Fujifilm X-T20 – 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 DC-G9:

  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • Better video: Provides higher movie framerates (4K/60p versus 4K/30p).
  • More detailed viewfinder: Has higher resolution electronic viewfinder (3680k vs 2360k dots).
  • Easier setting verification: Has an LCD display on top to control shooting parameters.
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (20 vs 8 flaps/sec) to capture the decisive moment.
  • Longer lasting: Can take more shots (400 versus 350) on a single battery charge.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • Sharper images: Has hand-shake reducing image stabilization build-in.
  • More modern: Is somewhat more recent (announced 9 months after the X-T20).

ilogo

Reasons to prefer the Fujifilm X-T20:

  • More detail: Has more megapixels (24 vs 20.2MP), which boosts linear resolution by 11%.
  • Better low-light imaging: Features bigger pixels on a larger sensor for better high-ISO images.
  • More compact: Is smaller (118x83mm vs 137x97mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 275g or 42 percent) and is thus easier to take along.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (47 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in January 2017).

If the count of relative strengths (bullet points above) is taken as a measure, the G9 is the clear winner of the match-up (11 : 7 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.

G9 11:07 X-T20

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 G9 or the X-T20 handle or perform in practice. 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 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.
