Panasonic G2 vs Sony NEX-5R
The Panasonic Lumix DMC-G2 and the Sony Alpha NEX-5R are two digital cameras that were revealed to the public, respectively, in March 2010 and August 2012. Both the G2 and the NEX-5R are mirrorless interchangeable lens cameras that are based on a Four Thirds (G2) and an APS-C (NEX-5R) sensor. The Panasonic has a resolution of 12 megapixels, whereas the Sony provides 16 MP.
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-G2 and the Sony Alpha NEX-5R? 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.
The physical size and weight of the Panasonic G2 and the Sony NEX-5R are illustrated in the side-by-side display below. 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 size dimensions are rounded to the nearest millimeter.
The G2 can be obtained in three different colors (black, blue, red), while the NEX-5R is available in two color-versions (black, silver).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony NEX-5R is considerably smaller (37 percent) than the Panasonic G2. Moreover, the NEX-5R is substantially lighter (36 percent) than the G2. In this context, it is worth noting that neither the G2 nor the NEX-5R are weather-sealed.
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 (G2) and the Sony E-Mount Lens Catalog (NEX-5R). 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.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will naturally be influenced heavily by the price. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The G2 was launched at a somewhat lower price (by 20 percent) than the NEX-5R, which makes it more attractive for photographers on a tight budget. 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.
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. 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Panasonic G2 features a Four Thirds sensor and the Sony NEX-5R an APS-C sensor. The sensor area in the NEX-5R is 62 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 G2 has a native 4:3 aspect ratio, while the one in the NEX-5R offers a 3:2 aspect.
With 16MP, the NEX-5R offers a higher resolution than the G2 (12MP), but the NEX-5R nevertheless has larger individual pixels (pixel pitch of 4.78μm versus 4.33μm for the G2) due to its larger sensor. Moreover, the NEX-5R is a much more recent model (by 2 years and 5 months) than the G2, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Sony NEX-5R implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the NEX-5R for good quality output (200 dots per inch) amounts to 24.6 x 16.3 inches or 62.4 x 41.5 cm, for very good quality (250 dpi) 19.6 x 13.1 inches or 49.9 x 33.2 cm, and for excellent quality (300 dpi) 16.4 x 10.9 inches or 41.6 x 27.6 cm. The corresponding values for the Panasonic G2 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-G2 has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the Sony Alpha NEX-5R are ISO 100 to ISO 25600 (no boost).
Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 NEX-5R offers substantially better image quality than the G2 (overall score 25 points higher). The advantage is based on 2.5 bits higher color depth, 2.8 EV in additional dynamic range, and 0.9 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 are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the NEX-5R provides a better video resolution than the G2. It can shoot movie footage at 1080/60i, while the Panasonic is limited to 720/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G2 has an electronic viewfinder (1440k dots), which can be very helpful when shooting in bright sunlight. In contrast, the NEX-5R relies on live view and the rear LCD for framing. That said, the NEX-5R can be equipped with an optional viewfinder – the FDA-EV1S. The table below summarizes some of the other core capabilities of the Panasonic G2 and Sony NEX-5R in connection with corresponding information for a sample of similar cameras.
One difference between the cameras concerns the presence of an on-board flash. The G2 has one, while the NEX-5R does not. While the built-in flash of the G2 is not very powerful, it can at times be useful as a fill-in light.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 G2 writes its imaging data to SDXC cards, while the NEX-5R uses SDXC or Memory Stick PRO Duo cards.
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-G2 and Sony Alpha NEX-5R and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.
| WiFi |
It is notable that the NEX-5R offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the G2 does not provide wifi capability.
Both the G2 and the NEX-5R have been discontinued, but can regularly be found used on eBay. The G2 was replaced by the Panasonic G3, while the NEX-5R was followed by the Sony NEX-5T. 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.
So how do things add up? Is the Panasonic G2 better than the Sony NEX-5R or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Panasonic Lumix DMC-G2:
- Easier framing: Has an electronic viewfinder for image composition and settings control.
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More affordable: Was introduced into a lower priced segment (20 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in March 2010).
Advantages of the Sony Alpha NEX-5R:
- More detail: Has more megapixels (16 vs 12MP), which boosts linear resolution by 18%.
- Better image quality: Scores substantially higher (25 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 (2.8 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (0.9 stops ISO advantage).
- Better video: Provides higher definition movie capture (1080/60i vs 720/30p).
- More detailed LCD: Has a higher resolution rear screen (920k vs 460k dots).
- Faster burst: Shoots at higher frequency (10 vs 2.6 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (111x59mm vs 124x84mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 152g or 36 percent) and is thus easier to take along.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
- More modern: Reflects 2 years and 5 months of technical progress since the G2 launch.
If the number of relative strengths (bullet points above) is taken as a guide, the NEX-5R is the clear winner of the contest (12 : 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.
How about other alternatives? Do the specifications of the Panasonic G2 and the Sony NEX-5R 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 G2 and the NEX-5R in practical situations. 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.
This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

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. Thus, a score needs to be put into the context of the launch date and the launch price 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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
