Body comparison

The physical size and weight of the Panasonic G1 and the Sony A77 II are illustrated 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 width, height and depth measures are rounded to the nearest millimeter.

Size Panasonic G1 vs Sony A77 II
Compare G1 versus A77 II top
Comparison G1 or A77 II rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A77 II is considerably larger (43 percent) than the Panasonic G1. Moreover, the A77 II is substantially heavier (80 percent) than the G1. It is noteworthy in this context that the A77 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. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the G1 gets 410 shots out of its Panasonic DMW-BLB13 battery, while the A77 II can take 480 images on a single charge of its Sony NP-FM500H power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G1 was launched at a markedly lower price (by 50 percent) than the A77 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 sensor inside a digital camera is one of the key determinants 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. 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 G1 features a Four Thirds sensor and the Sony A77 II an APS-C sensor. The sensor area in the A77 II is 63 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 G1 has a native 4:3 aspect ratio, while the one in the A77 II offers a 3:2 aspect.

Panasonic G1 and Sony A77 II sensor measures

With 24MP, the A77 II offers a higher resolution than the G1 (12MP), but the A77 II has smaller individual pixels (pixel pitch of 3.91μm versus 4.33μm for the G1). Yet, the A77 II is a much more recent model (by 5 years and 7 months) than the G1, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Sony A77 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A77 II for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Panasonic G1 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.

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 SLT-A77 II are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-51200.

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.

G1 versus A77 II MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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 A77 II offers substantially better image quality than the G1 (overall score 29 points higher). The advantage is based on 3.3 bits higher color depth, 3.1 EV in additional dynamic range, and 1.1 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.

One feature that differentiates the A77 II and the G1 is in-body image stabilization (IBIS). The A77 II reduces the risk of handshake-induced blur with all attached lenses, while the G1 offers no blur reduction with lenses that themselves do not provide optical image stabilization.

Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.

The G1 writes its imaging data to SDHC cards, while the A77 II uses SDXC or Memory Stick PRO Duo cards. The A77 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.

It is notable that the A77 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 provide wifi capability.

Studio photographers will appreciate that the Sony A77 II (unlike the G1) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the G1 and the A77 II have been discontinued, but can regularly be found used on ebay. The G1 was replaced by the Panasonic G2, while the A77 II does not have a direct successor. Further information on the features and operation of the G1 and A77 II can be found, respectively, in the Panasonic G1 Manual (free pdf) or the online Sony A77 II Manual.

Review summary

So what conclusions can be drawn? Is there a clear favorite between the Panasonic G1 and the Sony A77 II? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Arguments in favor of the Panasonic Lumix DMC-G1:

  • More compact: Is smaller (124x84mm vs 143x104mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 287g or 44 percent) and hence easier to carry around.
  • More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
  • More affordable: Was introduced into a lower priced category (50 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in September 2008).

ilogo

Advantages of the Sony Alpha SLT-A77 II:

  • More detail: Has more megapixels (24 vs 12MP), which boosts linear resolution by 44%.
  • Better image quality: Scores substantially higher (29 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (3.3 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (3.1 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (1.1 stops ISO advantage).
  • Broader imaging potential: Can capture not only stills but also 1080/60p video.
  • More detailed viewfinder: Has higher resolution electronic viewfinder (2359k vs 1440k dots).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.73x vs 0.70x).
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • 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 (12 vs 3 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (480 versus 410) out of a single battery charge.
  • 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.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
  • More modern: Reflects 5 years and 7 months of technical progress since the G1 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the A77 II is the clear winner of the contest (20 : 5 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

G1 05:20 A77 II

How about other alternatives? Do the specifications of the Panasonic G1 and the Sony A77 II place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says little about, for example, the shooting experience and imaging performance of the G1 and the A77 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 where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major camera 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.

Care should be taken when interpreting the review scores above, 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 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.
