Nikon D40X vs Sony HX400V
The Nikon D40X and the Sony Cyber-shot DSC-HX400V are two digital cameras that were officially introduced, respectively, in March 2007 and February 2014. The D40X is a DSLR, while the HX400V is a fixed lens compact. The cameras are based on an APS-C (D40X) and a 1/2.3-inch (HX400V) sensor. The Nikon has a resolution of 10 megapixels, whereas the Sony provides 20.2 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 D40X and the Sony Cyber-shot DSC-HX400V? 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.
An illustration of the physical size and weight of the Nikon D40X and the Sony HX400V is provided 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 width, height and depth dimensions are rounded to the nearest millimeter.
The D40X can be obtained in two different colors (black, silver), while the HX400V 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 Sony HX400V is somewhat larger (4 percent) than the Nikon D40X. In this context, it is worth noting that neither the D40X nor the HX400V are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the HX400V has a lens built in, whereas the D40X is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the D40X and their specifications in the Nikon Lens Catalog.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

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 HX400V was launched at a lower price than the D40X, despite having a lens built in. 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 size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 Nikon D40X features an APS-C sensor and the Sony HX400V a 1/2.3-inch sensor. The sensor area in the HX400V is 92 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 5.6. The sensor in the D40X has a native 3:2 aspect ratio, while the one in the HX400V offers a 4:3 aspect.
Despite having a smaller sensor, the HX400V offers a higher resolution of 20.2 megapixels, compared with 10 MP of the D40X. 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 1.18μm versus 6.11μm for the D40X). However, it should be noted that the HX400V is much more recent (by 6 years and 11 months) than the D40X, 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 HX400V has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Sony HX400V implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the HX400V for good quality output (200 dots per inch) amounts to 25.9 x 19.4 inches or 65.8 x 49.4 cm, for very good quality (250 dpi) 20.7 x 15.6 inches or 52.7 x 39.5 cm, and for excellent quality (300 dpi) 17.3 x 13 inches or 43.9 x 32.9 cm. The corresponding values for the Nikon D40X are 19.4 x 13 inches or 49.2 x 32.9 cm for good quality, 15.5 x 10.4 inches or 39.3 x 26.3 cm for very good quality, and 12.9 x 8.6 inches or 32.8 x 21.9 cm for excellent quality prints.
The Nikon D40X has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Sony Cyber-shot DSC-HX400V are ISO 80 to ISO 3200, with the possibility to increase the ISO range to 80-12800.
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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.
| DXO |
|12.||Olympus E-420||Four Thirds||10.0||3648||2736||none||21.5||10.4||527||56|

Many modern cameras cannot only take still pictures, but also record videos. The HX400V indeed provides for movie recording, while the D40X does not. The highest resolution format that the HX400V can use is 1080/60p.
Apart from body and sensor, cameras can and do differ across a range of features. For example, the HX400V has an electronic viewfinder (210k dots), while the D40X 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 D40X and Sony HX400V along with similar information for a selection of comparators.
The D40X writes its imaging data to SDHC cards, while the HX400V 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 Nikon D40X and Sony Cyber-shot DSC-HX400V and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the HX400V offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the D40X does not provide wifi capability.
Travel and landscape photographers will find it useful that the HX400V has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.
The HX400V is a recent model that features in the current product line-up of Sony. In contrast, the D40X has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the D40X was succeeded by the Nikon D60 . Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Nikon and Sony websites.
So what is the bottom line? Which of the two cameras – the Nikon D40X or the Sony HX400V – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.
Advantages of the Nikon D40X:

If the count of relative strengths (bullet points above) is taken as a measure, the HX400V is the clear winner of the contest (15 : 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the D40X or the HX400V. 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 where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). 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 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
