Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D3000 and the Sony Alpha A7 II? 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 D3000 vs Sony A7 II

The side-by-side display below illustrates the physical size and weight of the Nikon D3000 and the Sony A7 II. 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 size dimensions are rounded to the nearest millimeter.

Comparison D3000 or A7 II rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D3000 and the Sony A7 II are of equal size. However, the A7 II is markedly heavier (12 percent) than the D3000. It is noteworthy in this context that the A7 II is splash and dust-proof, while the D3000 does not feature any corresponding weather-sealing.

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 compare the optics available for the two cameras in the Nikon Lens Catalog (D3000) and the Sony FE Lens Catalog (A7 II). Mirrorless cameras, such as the A7 II, 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 D3000 gets 500 shots out of its EN-EL9a battery, while the A7 II can take 350 images on a single charge of its NP-FW50 power pack. The power pack in the A7 II can be charged via the USB port, 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. 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.

Any camera decision will naturally be influenced heavily by the price. 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 D3000 was launched at a markedly lower price (by 70 percent) than the A7 II, which puts it into a different market segment. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Nikon D3000 vs Sony A7 II

The size of the imaging sensor is a crucial determinant 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. 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Nikon D3000 features an APS-C sensor and the Sony A7 II a full frame sensor. The sensor area in the A7 II is 129 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Nikon D3000 and Sony A7 II sensor measures

With 24MP, the A7 II offers a higher resolution than the D3000 (10MP), but the A7 II has smaller individual pixels (pixel pitch of 5.97μm versus 6.11μm for the D3000). Yet, the A7 II is a much more recent model (by 5 years and 3 months) than the D3000, 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 A7 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7 II for good quality output (200 dots per inch) amounts to 30 x 20 inch or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inch or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inch or 50.8 x 33.9 cm. The corresponding values for the Nikon D3000 are 19.4 x 13 inch or 49.2 x 32.9 cm for good quality, 15.5 x 10.4 inch or 39.3 x 26.3 cm for very good quality, and 12.9 x 8.6 inch or 32.8 x 21.9 cm for excellent quality prints.

The A7 II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Nikon D3000 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 Alpha A7 II are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-51200.

D3000 versus A7 II MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). Of the two cameras under consideration, the A7 II offers substantially better image quality than the D3000 (overall score 28 points higher). The advantage is based on 2.6 bits higher color depth, 2.5 EV in additional dynamic range, and 2.1 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.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The A7 II indeed provides for movie recording, while the D3000 does not. The highest resolution format that the A7 II can use is 1080/60p.

 

Feature comparison: Nikon D3000 vs Sony A7 II

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A7 II has an electronic viewfinder (2400k dots), while the D3000 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 viewfinder in the A7 II offers a wider field of view (100%) than the one in the D3000 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the A7 II has a higher magnification (0.71x vs 0.53x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Nikon D3000 and Sony A7 II in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The D3000 has one, while the A7 II does not. While the built-in flash of the D3000 is not very powerful, it can at times be useful as a fill-in light.

The D3000 writes its imaging data to SDHC cards, while the A7 II uses SDXC or Memory Stick PRO Duo cards. The A7 II supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the D3000 cannot take advantage of Ultra High Speed SD cards.

 

Connectivity comparison: Nikon D3000 vs Sony A7 II

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.

If the count of relative strengths (bullet points above) is taken as a measure, the A7 II is the clear winner of the contest (21 : 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 D3000 and the Sony A7 II place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.

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 D3000 or the A7 II. 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 D3000 vs Sony A7 II

This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
