Nikon P7800 vs Sony NEX-7
The Nikon Coolpix P7800 and the Sony Alpha NEX-7 are two digital cameras that were revealed to the public, respectively, in September 2013 and August 2011. The P7800 is a fixed lens compact, while the NEX-7 is a mirrorless interchangeable lens camera. The cameras are based on a 1/1.7-inch (P7800) and an APS-C (NEX-7) sensor. The Nikon has a resolution of 12 megapixels, whereas the Sony provides 24 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 Coolpix P7800 and the Sony Alpha NEX-7? 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.
The physical size and weight of the Nikon P7800 and the Sony NEX-7 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony NEX-7 is notably smaller (13 percent) than the Nikon P7800. In this context, it is worth noting that neither the P7800 nor the NEX-7 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the P7800 has a lens built in, whereas the NEX-7 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 NEX-7 and their specifications in the Sony E-Mount 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 manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The P7800 was launched at a lower price than the NEX-7, 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 imaging sensor is a crucial determinant 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 P7800 features a 1/1.7-inch sensor and the Sony NEX-7 an APS-C sensor. The sensor area in the NEX-7 is 749 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.5 and 1.5. The sensor in the P7800 has a native 4:3 aspect ratio, while the one in the NEX-7 offers a 3:2 aspect.
With 24MP, the NEX-7 offers a higher resolution than the P7800 (12MP), but the NEX-7 nevertheless has larger individual pixels (pixel pitch of 3.90μm versus 1.89μm for the P7800) due to its larger sensor. However, the P7800 is a much more recent model (by 2 years) than the NEX-7, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Sony NEX-7 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the NEX-7 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 cm. The corresponding values for the Nikon P7800 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.
The Nikon Coolpix P7800 has a native sensitivity range from ISO 80 to ISO 3200, which can be extended to ISO 80-6400. The corresponding ISO settings for the Sony Alpha NEX-7 are ISO 100 to ISO 16000 (no boost).
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"). Of the two cameras under consideration, the NEX-7 offers substantially better image quality than the P7800 (overall score 27 points higher). The advantage is based on 2.9 bits higher color depth, 1.7 EV in additional dynamic range, and 2.3 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.
|10.||Olympus Stylus 1||1/1.7||11.8||3968||2976||1080/30p||20.7||11.6||179||51|
|17.||Sony RX1||Full Frame||24.0||6000||4000||1080/60p||25.1||14.3||2534||93|
|Note: DXO values in italics represent estimates based on sensor size and age.|
Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the NEX-7 provides a faster frame rate than the P7800. It can shoot movie footage at 1080/60i, while the Nikon is limited to 1080/30p.
Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the NEX-7 offers a substantially higher resolution than the one in the P7800 (2359k vs 921k dots). The following table reports on some other key feature differences and similarities of the Nikon P7800, the Sony NEX-7, and comparable cameras.

The Nikon P7800 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 P7800 writes its imaging data to SDXC cards, while the NEX-7 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 Coolpix P7800 and Sony Alpha NEX-7 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the P7800 and the NEX-7 have been discontinued, but can regularly be found used on eBay. Neither of the two has a direct successor, so they represent the end of the respective camera lines from Nikon and Sony. 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 how do things add up? Which of the two cameras – the Nikon P7800 or the Sony NEX-7 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Nikon Coolpix P7800:
- More flexible LCD: Has a 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.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Ready to shoot: Has a lens built-in, whereas the NEX-7 requires a separate lens.
- Sharper images: Has hand-shake reducing image stabilization built-in.
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More modern: Reflects 2 years of technical progress since the NEX-7 launch.
Reasons to prefer the Sony Alpha NEX-7:
- More detail: Has more megapixels (24 vs 12MP), which boosts linear resolution by 44%.
- Better image quality: Scores substantially higher (27 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (2.9 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (1.7 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (2.3 stops ISO advantage).
- Better video: Provides higher movie framerates (1080/60i versus 1080/30p).
- More detailed viewfinder: Has higher resolution electronic viewfinder (2359k vs 921k dots).
- Faster burst: Shoots at higher frequency (10 vs 8 flaps/sec) to capture the decisive moment.
- More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
- More compact: Is smaller (120x67mm vs 119x78mm) and will fit more readily into a bag.
- Longer lasting: Gets more shots (430 versus 350) out of a single battery charge.
- More heavily discounted: Has been around for much longer (launched in August 2011).
If the count of individual advantages (bullet points above) is taken as a guide, the NEX-7 is the clear winner of the contest (12 : 7 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 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.
How about other alternatives? Do the specifications of the Nikon P7800 and the Sony NEX-7 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best Mirrorless Interchangeable Lens 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 P7800 or the NEX-7. 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], digitalcameraworld [DCW], 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.

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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
