Body comparison

The side-by-side display below illustrates the physical size and weight of the Sony A7S II and the Panasonic G7. The two cameras are presented according to their relative size. 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.

The G7 can be obtained in two different colors (black, silver), while the A7S II is only available in black.

Size Sony A7S II vs Panasonic G7
Compare A7S II versus G7 top
Comparison A7S II or G7 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic G7 is notably smaller (12 percent) than the Sony A7S II. Moreover, the G7 is substantially lighter (35 percent) than the A7S II. It is worth mentioning in this context that the A7S II is splash and dust resistant, while the G7 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 compare the optics available for the two cameras in the Sony FE Lens Catalog (A7S II) and the Micro Four Thirds Lens Catalog (G7). 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 A7S II gets 370 shots out of its Sony NP-FW50 battery, while the G7 can take 350 images on a single charge of its Panasonic DMW-BLC12 power pack. The power pack in the A7S II can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Note: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The G7 was launched at a markedly lower price (by 78 percent) than the A7S II, 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.

Sensor comparison

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Sony A7S II features a full frame sensor and the Panasonic G7 a Four Thirds sensor. The sensor area in the G7 is 73 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.0. The sensor in the A7S II has a native 3:2 aspect ratio, while the one in the G7 offers a 4:3 aspect.

Sony A7S II and Panasonic G7 sensor measures

Despite having a smaller sensor, the G7 offers a higher resolution of 15.8 megapixels, compared with 12 MP of the A7S II. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.77μm versus 8.40μm for the A7S II). Moreover, it should be noted that the A7S II is a somewhat more recent model (by 3 months) than the G7, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The resolution advantage of the Panasonic G7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the G7 for good quality output (200 dots per inch) amounts to 23 x 17.2 inches or 58.3 x 43.8 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.7 x 35 cm, and for excellent quality (300 dpi) 15.3 x 11.5 inches or 38.9 x 29.2 cm. The corresponding values for the Sony A7S II are 21.2 x 14.2 inches or 53.8 x 36 cm for good quality, 17 x 11.3 inches or 43.1 x 28.8 cm for very good quality, and 14.1 x 9.4 inches or 35.9 x 24 cm for excellent quality prints.

The Sony Alpha 7S II has a native sensitivity range from ISO 100 to ISO 102400, which can be extended to ISO 50-409600. The corresponding ISO settings for the Panasonic Lumix DMC-G7 are ISO 160 to ISO 25600 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One feature that differentiates the A7S II and the G7 is in-body image stabilization (IBIS). The A7S II reduces the risk of handshake-induced blur with all attached lenses, while the G7 offers no blur reduction with lenses that themselves do not provide optical image stabilization.

The G7 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the A7S II does not have a selfie-screen.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, both cameras under consideration feature an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The Panasonic G7 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.

The A7S II writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the G7 uses SDXC cards. The G7 supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the A7S II can use UHS-I cards (up to 104 MB/s).

Review summary

So what conclusions can be drawn? Which of the two cameras – the Sony A7S II or the Panasonic G7 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Arguments in favor of the Sony Alpha 7S II:

  • Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
  • Richer colors: The pixel size advantage translates into images with better, more accurate colors.
  • More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
  • Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.78x vs 0.70x).
  • More detailed LCD: Has a higher resolution rear screen (1229k vs 1040k dots).
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
  • Sharper images: Has hand-shake reducing image stabilization built-in.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More modern: Is somewhat more recent (announced 3 months after the G7).

ilogo

Reasons to prefer the Panasonic Lumix DMC-G7:

  • More detail: Has more megapixels (15.8 vs 12MP), which boosts linear resolution by 13%.
  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster burst: Shoots at higher frequency (7 vs 5 flaps/sec) to capture the decisive moment.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More compact: Is smaller (125x86mm vs 127x96mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 217g or 35 percent) and is thus easier to take along.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
  • More affordable: Was introduced into a lower priced category (78 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in May 2015).

If the count of individual advantages (bullet points above) is taken as a guide, the A7S II comes out slightly ahead of the G7 (13 : 12 points). 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. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

A7S II 13:12 G7

How about other alternatives? Do the specifications of the Sony A7S II and the Panasonic G7 place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing whether the two cameras rank among the cream of the crop.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the A7S II or the G7 perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

Expert reviews

This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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.
