Panasonic GX1 versus Panasonic G5
The Panasonic Lumix DMC-GX1 and the Panasonic Lumix DMC-G5 are two digital cameras that were revealed to the public, respectively, in November 2011 and July 2012. Both the GX1 and the G5 are mirrorless interchangeable lens cameras that are equipped with a Four Thirds sensor. The GX1 has a resolution of 15.8 megapixel, whereas the G5 provides 15.9 MP.
An illustration of the physical size and weight of the Panasonic GX1 and the Panasonic G5 is provided in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All size dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left side – the GX1 – represents the basis for the calculations 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 Panasonic G5 is notably larger (26 percent) than the Panasonic GX1. Moreover, the G5 is markedly heavier (25 percent) than the GX1. In this context, it is worth noting that neither the GX1 nor the G5 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can find an overview of suitable optics in the Micro Four Thirds Lens Catalog. 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 table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The G5 was launched at a markedly lower price (by 37 percent) than the GX1, 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Both cameras under consideration feature a Four Thirds sensor and have a format factor (sometimes also referred to as "crop factor") of 2.0. Within the spectrum of camera sensors, this places the review cameras among the medium-sized sensor cameras that aim to strike a balance between image quality and portability. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.
While the two cameras under review share the same sensor size, the G5 offers a slightly higher resolution of 15.9 megapixel, compared with 15.8 MP of the GX1. This megapixel advantage translates into a 0.3 percent gain in linear resolution. On the other hand, these sensor specs imply that the G5 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.76μm versus 3.77μm for the GX1). However, it should be noted that the G5 is a somewhat more recent model (by 8 months) than the GX1, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (1080/60p).
Beyond body and sensor, cameras can and do differ across a range of features. For example, the G5 has an electronic viewfinder (1440k dots), which can be very helpful when shooting in bright sunlight. In contrast, the GX1 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Panasonic GX1 and Panasonic G5 in connection with corresponding information for a sample of similar cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

Both the GX1 and the G5 have been discontinued, but can regularly be found used on ebay. The GX1 was replaced by the Panasonic GX7, while the G5 was followed by the Panasonic G6.
So how do things add up? Is there a clear favorite between the Panasonic GX1 and the Panasonic GX1? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Panasonic Lumix DMC-GX1:
- More compact: Is smaller (116x68mm vs 120x83mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 78g or 20 percent) and hence easier to carry around.
- More heavily discounted: Has been on the market for longer (launched in November 2011).
Reasons to prefer the Panasonic Lumix DMC-G5:
- Easier framing: Has an electronic viewfinder for image framing and settings control.
- More detailed LCD: Has a higher resolution rear screen (920k vs 460k dots).
- More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
- Faster burst: Shoots at higher frequency (6 vs 4.2 flaps/sec) to capture the decisive moment.
- More affordable: Was introduced into a lower priced category (37 percent cheaper at launch).
- More modern: Was introduced somewhat (8 months) more recently.
If the count of relative strengths (bullet points above) is taken as a measure, the G5 emerges as the winner of the match-up (6 : 3 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.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the GX1 and the G5 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. This is where reviews by experts come in. The following table reports the overall rankings of the cameras as published by some of the major camera review sites. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
In case you would like to check on the differences and similarities of other camera models, just make your choice using the following search menu. There is also a set of direct links to comparison reviews that other users of the CAM-parator app explored. If the camera you are interested in is not available, please contact me, and I will try to add information on that model to the database.
