Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon Coolpix W150 and the Sony Alpha A7R IIIA? 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

An illustration of the physical size and weight of the Nikon W150 and the Sony A7R IIIA 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 measures are rounded to the nearest millimeter.

The W150 can be obtained in five different colors (blue, orange, white, flower, resort), while the A7R IIIA 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 A7R IIIA is considerably larger (65 percent) than the Nikon W150. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments. More than that, the W150 is water-proof up to 10m and can, thus, be used for underwater photography.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the W150 has a lens built in, whereas the A7R IIIA 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 A7R IIIA and their specifications in the Sony FE Lens Catalog.

The battery packs of both cameras can be charged via USB, which can be very convenient when travelling.

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

Any camera decision will obviously take relative prices into account. 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 W150 was launched at a lower price than the A7R IIIA, 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.

Sensor comparison

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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Nikon W150 features a 1/3.1-inch sensor and the Sony A7R IIIA a full frame sensor. The sensor area in the A7R IIIA is 5288 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 7.4 and 1.0. The sensor in the W150 has a native 4:3 aspect ratio, while the one in the A7R IIIA offers a 3:2 aspect.

With 42.2MP, the A7R IIIA offers a higher resolution than the W150 (13MP), but the A7R IIIA nevertheless has larger individual pixels (pixel pitch of 4.52μm versus 1.11μm for the W150) due to its larger sensor. Moreover, the A7R IIIA is a somewhat more recent model (by 1 year and 11 months) than the W150, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The resolution advantage of the Sony A7R IIIA implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7R IIIA for good quality output (200 dots per inch) amounts to 39.8 x 26.5 inches or 101 x 67.4 cm, for very good quality (250 dpi) 31.8 x 21.2 inches or 80.8 x 53.9 cm, and for excellent quality (300 dpi) 26.5 x 17.7 inches or 67.3 x 44.9 cm. The corresponding values for the Nikon W150 are 20.8 x 15.6 inches or 52.8 x 39.6 cm for good quality, 16.6 x 12.5 inches or 42.3 x 31.7 cm for very good quality, and 13.9 x 10.4 inches or 35.2 x 26.4 cm for excellent quality prints.

The A7R IIIA has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Unlike the W150, the A7R IIIA has the capacity to capture high quality composite images by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

The Nikon Coolpix W150 has a native sensitivity range from ISO 125 to ISO 1600. The corresponding ISO settings for the Sony Alpha A7R IIIA are ISO 100 to ISO 32000, with the possibility to increase the ISO range to 50-102400.

In terms of underlying technology, the W150 is build around a CMOS sensor, while the A7R IIIA uses a BSI-CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Note: DXO values in italics represent estimates based on sensor size and age.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the A7R IIIA provides a better video resolution than the W150. It can shoot movie footage at 4K/30p, while the Nikon is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the A7R IIIA has an electronic viewfinder (3686k dots), which can be very helpful when shooting in bright sunlight. In contrast, the W150 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Nikon W150 and Sony A7R IIIA in connection with corresponding information for a sample of similar cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One difference between the cameras concerns the presence of an on-board flash. The W150 has one, while the A7R IIIA does not. While the built-in flash of the W150 is not very powerful, it can at times be useful as a fill-in light.

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, both cameras under consideration feature an 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 Sony A7R IIIA 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 W150 writes its imaging data to SDXC cards, while the A7R IIIA uses SDXC or Memory Stick PRO Duo cards. The A7R IIIA features dual card slots, which can be very useful in case a memory card fails. In contrast, the W150 only has one slot. The A7R IIIA supports UHS-II cards on its first slot and UHS-I on its second one, while the W150 cannot take advantage of Ultra High Speed SD cards.

Connectivity comparison

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 W150 and Sony Alpha A7R IIIA and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7R IIIA has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The W150 does not feature such a mic input.

Studio photographers will appreciate that the Sony A7R IIIA (unlike the W150) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The A7R IIIA is a recent model that features in the current product line-up of Sony. In contrast, the W150 has been discontinued (but can be found pre-owned on ebay). There has not been a direct replacement model for the W150 from Nikon. Further information on the features and operation of the W150 and A7R IIIA can be found, respectively, in the Nikon W150 Manual (free pdf) or the online Sony A7R IIIA Manual.

Review summary

So how do things add up? Is there a clear favorite between the Nikon W150 and the Sony A7R IIIA? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Reasons to prefer the Nikon Coolpix W150:

• Ready to shoot: Has a lens built-in, whereas the A7R IIIA requires a separate lens.

If the count of individual advantages (bullet points above) is taken as a guide, the A7R IIIA is the clear winner of the contest (28 : 7 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.

How about other alternatives? Do the specifications of the Nikon W150 and the Sony A7R IIIA 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 W150 or the A7R IIIA. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
