Nikon D4S vs Panasonic G1

The Nikon D4S and the Panasonic Lumix DMC-G1 are two digital cameras that were announced, respectively, in February 2014 and September 2008. The D4S is a DSLR, while the G1 is a mirrorless interchangeable lens camera. The cameras are based on a full frame (D4S) and a Four Thirds (G1) sensor. The Nikon has a resolution of 16.2 megapixels, whereas the Panasonic provides 12 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 Nikon D4S and the Panasonic Lumix DMC-G1? 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: Nikon D4S vs Panasonic G1

An illustration of the physical size and weight of the Nikon D4S and the Panasonic G1 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter.

Size Nikon D4S vs Panasonic G1
Compare D4S versus G1 top
Comparison D4S or G1 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Panasonic G1 is considerably smaller (59 percent) than the Nikon D4S. Moreover, the G1 is substantially lighter (73 percent) than the D4S. It is worth mentioning in this context that the D4S is splash and dust resistant, 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 Nikon Lens Catalog (D4S) and the Micro Four Thirds Lens Catalog (G1). Mirrorless cameras, such as the G1, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.

Concerning battery life, the D4S gets 3020 shots out of its EN-EL18a battery, while the G1 can take 410 images on a single charge of its DMW-BLB13 power pack. As can be seen in the images above, the D4S has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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 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 G1 was launched at a markedly lower price (by 91 percent) than the D4S, 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.

 

Sensor comparison: Nikon D4S vs Panasonic G1

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. 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Nikon D4S features a full frame sensor and the Panasonic G1 a Four Thirds sensor. The sensor area in the G1 is 74 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 D4S has a native 3:2 aspect ratio, while the one in the G1 offers a 4:3 aspect.

Nikon D4S and Panasonic G1 sensor measures

With 16.2MP, the D4S offers a higher resolution than the G1 (12MP), but the D4S nevertheless has larger individual pixels (pixel pitch of 7.29μm versus 4.33μm for the G1) due to its larger sensor. Moreover, the D4S is a much more recent model (by 5 years and 5 months) than the G1, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The resolution advantage of the Nikon D4S implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D4S for good quality output (200 dots per inch) amounts to 24.6 x 16.4 inch or 62.6 x 41.7 cm, for very good quality (250 dpi) 19.7 x 13.1 inch or 50.1 x 33.3 cm, and for excellent quality (300 dpi) 16.4 x 10.9 inch or 41.7 x 27.8 cm. The corresponding values for the Panasonic G1 are 20 x 15 inch or 50.8 x 38.1 cm for good quality, 16 x 12 inch or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inch or 33.9 x 25.4 cm for excellent quality prints.

The Nikon D4S has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 50-409600. The corresponding ISO settings for the Panasonic Lumix DMC-G1 are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 100-3200.

D4S versus G1 MP

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. Of the two cameras under review, the D4S provides substantially higher image quality than the G1, with an overall score that is 36 points higher. This advantage is based on 3.3 bits higher color depth, 3 EV in additional dynamic range, and 2.7 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. The D4S indeed provides movie recording capabilities, while the G1 does not. The highest resolution format that the D4S can use is 1080/60p.

 

Feature comparison: Nikon D4S vs Panasonic G1

Apart from body and sensor, cameras can and do differ across a range of features. For example, the G1 has an electronic viewfinder (1440k dots), while the D4S has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinders of both cameras offer the same field of view (100%), as well as the same magnification (0.70x). The adjacent table lists some of the other core features of the Nikon D4S and Panasonic G1 along with similar information for a selection of comparators.

One feature that is present on the D4S, but is missing on the G1 is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The G1 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 D4S does not have a selfie-screen.

The Nikon D4S 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 D4S writes its imaging data to Compact Flash or XQD cards, while the G1 uses SDHC cards. The D4S features dual card slots, which can be very useful in case a memory card fails. In contrast, the G1 only has one slot.

 

Connectivity comparison: Nikon D4S vs Panasonic G1

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 Nikon D4S and Panasonic Lumix DMC-G1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Nikon D4S (unlike the G1) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the D4S and the G1 have been discontinued, but can regularly be found used on eBay. The G1 was replaced by the Panasonic G2, while the D4S was followed by the Nikon D5. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Nikon and Panasonic websites.


Review summary: Nikon D4S vs Panasonic G1

So what conclusions can be drawn? Is there a clear favorite between the Nikon D4S and the Panasonic G1? 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 framing info: Has an electronic viewfinder that displays shooting data.
  • More flexible LCD: Has 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 160x157mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 990g or 73 percent) and is thus easier to take along.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (91 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in September 2008).

If the count of individual advantages (bullet points above) is taken as a guide, the D4S is the clear winner of the match-up (19 : 9 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. 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.

D4S 19:09 G1

How about other alternatives? Do the specifications of the Nikon D4S and the Panasonic G1 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings 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 says little about, for example, the shooting experience and imaging performance of the D4S and the G1 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.

Expert reviews: Nikon D4S vs Panasonic G1

This is where reviews by experts come in. 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 were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
