Panasonic G1 vs Sony A7S II

The Panasonic Lumix DMC-G1 and the Sony Alpha 7S II are two digital cameras that were announced, respectively, in September 2008 and September 2015. Both the G1 and the A7S II are mirrorless interchangeable lens cameras that are based on a Four Thirds (G1) and a full frame (A7S II) sensor. Both cameras offer a resolution of 12 megapixels.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Going beyond this snapshot of core features and characteristics, what are the differences between the Panasonic Lumix DMC-G1 and the Sony Alpha 7S II? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.

Body comparison

An illustration of the physical size and weight of the Panasonic G1 and the Sony A7S II is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

Size Panasonic G1 vs Sony A7S II
Compare G1 versus A7S II top
Comparison G1 or A7S II rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A7S II is notably larger (17 percent) than the Panasonic G1. Moreover, the A7S II is substantially heavier (74 percent) than the G1. It is noteworthy in this context that the A7S II is splash and dust-proof, while the G1 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 Micro Four Thirds Lens Catalog (G1) and the Sony FE Lens Catalog (A7S II). 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 G1 gets 410 shots out of its DMW-BLB13 battery, while the A7S II can take 370 images on a single charge of its NP-FW50 power pack. The power pack in the A7S II can be charged via the USB port, which can be very convenient when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

Note: Measurements and pricing do not include easily detachable parts, such as 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 G1 was launched at a markedly lower price (by 80 percent) than the A7S II, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 size of the imaging sensor is a crucial determinant 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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 G1 features a Four Thirds sensor and the Sony A7S II a full frame sensor. The sensor area in the A7S II is 276 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.0. The sensor in the G1 has a native 4:3 aspect ratio, while the one in the A7S II offers a 3:2 aspect.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.

Panasonic G1 and Sony A7S II sensor measures

Even though the A7S II has a larger sensor, both cameras offer the same resolution of 12 megapixels. This implies that the A7S II has a lower pixel density and larger individual pixels (with a pixel pitch of 8.40μm versus 4.33μm for the G1), which gives it a potential advantage in terms of light gathering capacity. In addition, the A7S II is much more recent (by 7 years) than the G1, and its sensor will have benefitted from technological advances during this time.

The Panasonic Lumix DMC-G1 has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Sony Alpha 7S II are ISO 100 to ISO 102400, with the possibility to increase the ISO range to 50-409600.

G1 versus A7S II MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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"). Of the two cameras under consideration, the A7S II offers substantially better image quality than the G1 (overall score 32 points higher). The advantage is based on 2.5 bits higher color depth, 3 EV in additional dynamic range, and 2.7 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. The A7S II indeed provides for movie recording, while the G1 does not. The highest resolution format that the A7S II can use is 4K/30p.

 

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the A7S II offers a substantially higher resolution than the one in the G1 (2400k vs 1440k dots).

One difference between the cameras concerns the presence of an on-board flash. The G1 has one, while the A7S II does not. While the built-in flash of the G1 is not very powerful, it can at times be useful as a fill-in light.

The G1 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping 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, the A7S II is one of those camera that have an additional 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 G1 writes its imaging data to SDHC cards, while the A7S II uses SDXC or Memory Stick PRO Duo cards. The A7S II supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the G1 cannot take advantage of Ultra High Speed SD cards.

 

Connectivity comparison

For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Panasonic Lumix DMC-G1 and Sony Alpha 7S II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7S II offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the G1 does not offer wifi capability.

The A7S II is a recent model that features in the current product line-up of Sony. In contrast, the G1 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the G1 was succeeded by the Panasonic G2. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Panasonic and Sony websites.


Review summary

So how do things add up? Is there a clear favorite between the Panasonic G1 and the Sony A7S II? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Advantages of the Panasonic Lumix DMC-G1:

  • More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • More compact: Is smaller (124x84mm vs 127x96mm) and thus needs less room in the bag.

  • Longer lasting: Can take more shots (410 versus 370) on a single battery charge.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More affordable: Was introduced into a lower priced category (80 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in September 2008).

ilogo

Arguments in favor of the Sony Alpha 7S II:

  • Better image quality: Scores substantially higher (32 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (2.5 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (3 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (2.7 stops ISO advantage).
  • Broader imaging potential: Can capture not only stills but also 4K/30p video.
  • More detailed viewfinder: Has higher resolution electronic viewfinder (2400k vs 1440k dots).
  • 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 460k dots).
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More modern: Reflects 7 years of technical progress since the G1 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the A7S II is the clear winner of the contest (17 : 8 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. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

G1 08:17 A7S II

How about other alternatives? Do the specifications of the Panasonic G1 and the Sony A7S II 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the G1 and the A7S II 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.

Expert reviews

This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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.

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

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
