Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon 1 J4 and the Nikon D40? 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 1 J4 vs D40
An illustration of the physical size and weight of the Nikon 1 J4 and the Nikon D40 is provided 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 dimensions are rounded to the nearest millimeter.
The J4 can be obtained in four different colors (black, silver, orange, white), while the D40 is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D40 is considerably larger (94 percent) than the Nikon 1 J4. Moreover, the D40 is substantially heavier (125 percent) than the J4. In this context, it is worth noting that neither the J4 nor the D40 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. 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.
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 camera comparisons there.

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 D40 was somewhat cheaper (by 9 percent) than the J4 at launch, but both cameras fall into the same price category. 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: Nikon 1 J4 vs D40
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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Nikon 1 J4 features an one-inch sensor and the Nikon D40 an APS-C sensor. The sensor area in the D40 is 219 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Despite having a smaller sensor, the Nikon 1 J4 offers a higher resolution of 18.2 megapixels, compared with 6 MP of the Nikon D40. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 2.52μm versus 7.85μm for the D40). However, it should be noted that the J4 is much more recent (by 7 years and 4 months) than the D40, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the J4 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Nikon 1 J4 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the J4 for good quality output (200 dots per inch) amounts to 26.2 x 17.4 inch or 66.4 x 44.3 cm, for very good quality (250 dpi) 20.9 x 14 inch or 53.2 x 35.4 cm, and for excellent quality (300 dpi) 17.4 x 11.6 inch or 44.3 x 29.5 cm. The corresponding values for the Nikon D40 are 15 x 10 inch or 38.2 x 25.4 cm for good quality, 12 x 8 inch or 30.6 x 20.3 cm for very good quality, and 10 x 6.7 inch or 25.5 x 16.9 cm for excellent quality prints.
The J4 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Nikon 1 J4 has a native sensitivity range from ISO 160 to ISO 12800. The corresponding ISO settings for the Nikon D40 are ISO 200 to ISO 1600, with the possibility to increase the ISO range to 200-3200.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. 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 differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The J4 has a touchscreen, while the D40 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.
The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the J4 is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The J4 writes its imaging data to micro SDXC cards, while the D40 uses SDHC cards. The J4 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the D40 cannot take advantage of Ultra High Speed SD cards.
Connectivity comparison: Nikon 1 J4 vs D40
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 1 J4 and Nikon D40 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the J4 offers wifi support, while the D40 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the J4 and the D40 have been discontinued, but can regularly be found used on eBay. The D40 was replaced by the Nikon D40X, while the J4 was followed by the Nikon 1 J5. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Nikon website.
Review summary: Nikon 1 J4 vs D40
So what conclusions can be drawn? Is the Nikon 1 J4 better than the Nikon D40 or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Nikon 1 J4:
- More detail: Offers more megapixels (18.2 vs 6MP) with a 74% higher linear resolution.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Broader imaging potential: Can record not only still images but also 1080/60p movies.
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- Larger screen: Has a bigger rear LCD (3.0" vs 2.5") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (1037k vs 230k dots).
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- Faster burst: Shoots at higher frequency (60 vs 2.5 flaps/sec) to capture the decisive moment.
- Less disturbing: Has an electronic shutter option for completely silent shooting.
- More compact: Is smaller (100x60mm vs 124x94mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 290g or 56 percent) and hence easier to carry around.
- More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
- Easier file upload: Has wifi built in for automatic backup or image transfer to the web.

Advantages of the Nikon D40:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better low-light sensitivity: Can shoot in dim conditions (0.4 stops ISO advantage).
- Easier framing: Has an optical viewfinder for image framing and settings control.
- Longer lasting: Gets more shots (470 versus 300) out of a single battery charge.
- Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
- More heavily discounted: Has been around for much longer (launched in November 2006).
If the count of relative strengths (bullet points above) is taken as a measure, the J4 is the clear winner of the match-up (15 : 6 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 Nikon 1 J4 and the Nikon D40 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the J4 or the D40. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.
Expert reviews: Nikon 1 J4 vs D40
This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major 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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
