Nikon D3400 versus Panasonic G7

The Nikon D3400 and the Panasonic Lumix DMC-G7 are two digital cameras that were officially introduced, respectively, in August 2016 and May 2015. The D3400 is a DSLR, while the G7 is a mirrorless interchangeable lens camera. The cameras are based on an APS-C (D3400) and a Four Thirds (G7) sensor. The Nikon has a resolution of 24 megapixel, whereas the Panasonic provides 15.8 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Nikon D3400 vs Panasonic G7

The physical size and weight of the Nikon D3400 and the Panasonic G7 are illustrated 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. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left side – the D3400 – 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 G7 is notably smaller (12 percent) than the Nikon D3400. Moreover, the G7 is markedly lighter (8 percent) than the D3400. In this context, it is worth noting that neither the D3400 nor the G7 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 find an overview of optics for the two cameras in the Nikon Lens Catalog (D3400) and the Micro Four Thirds Lens Catalog (G7). Mirrorless cameras, such as the G7, 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 D3400 gets 1200 shots out of its EN-EL14a battery, while the G7 can take 350 images on a single charge of its DMW-BLC12 power pack.

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

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 D3400 was launched at a somewhat lower price (by 23 percent) than the G7, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Nikon D3400 vs Panasonic G7

The size of the sensor inside a digital camera is one of the key determinants 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. 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 Nikon D3400 features an APS-C sensor and the Panasonic G7 a Four Thirds sensor. The sensor area in the G7 is 39 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.0. The sensor in the D3400 has a native 3:2 aspect ratio, while the one in the G7 offers a 4:3 aspect.

Nikon D3400 and Panasonic G7 sensor measures

With 24MP, the D3400 offers a higher resolution than the G7 (15.8MP), but the D3400 nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 3.77μm for the G7) due to its larger sensor. Moreover, the D3400 is a somewhat more recent model (by 1 year and 3 months) than the G7, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. Coming back to sensor resolution, it should be mentioned that the D3400 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the G7 provides a better video resolution than the D3400. It can shoot movie footage at 4K/30p, while the Nikon is limited to 1080/60p.

 

Feature comparison: Nikon D3400 vs Panasonic G7

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the G7 has an electronic viewfinder (2360k dots), while the D3400 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 adjacent table lists some of the other core features of the Nikon D3400 and Panasonic G7 along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The G7 has a touchscreen, while the D3400 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The reported shutter speed and shutter burst refer to the use of the mechanical shutter. In addition, the G7 features an electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (rolling shutter) or shooting under artificial light sources (flickering).

Both the D3400 and the G7 write their imaging data to SDXC cards.

  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • More heavily discounted: Has been on the market for longer (launched in May 2015).

If the count of individual advantages (bullet points above) is taken as a guide, the G7 comes out slightly ahead of the D3400 (12 : 11 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.

D3400 11:12 G7

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the D3400 and the G7 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 why expert reviews are important. The table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The above review scores should be interpreted 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 comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
