Nikon D3 vs Sony A77 II
The Nikon D3 and the Sony Alpha SLT-A77 II are two digital cameras that were revealed to the public, respectively, in August 2007 and May 2014. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (D3) and an APS-C (A77 II) sensor. The Nikon has a resolution of 12.1 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 D3 and the Sony Alpha SLT-A77 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 D3 vs Sony A77 II
An illustration of the physical size and weight of the Nikon D3 and the Sony A77 II 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 size 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 A77 II is considerably smaller (41 percent) than the Nikon D3. Moreover, the A77 II is substantially lighter (50 percent) than the D3. 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.
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.
Concerning battery life, the D3 gets 4300 shots out of its EN-EL4a battery, while the A77 II can take 480 images on a single charge of its NP-FM500H power pack. As can be seen in the images above, the D3 has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. In order to provide similar functionality for the A77 II, Sony provides the VG-C77AM vertical grip as an optional accessory (see here on eBay).

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The A77 II was launched at a markedly lower price (by 76 percent) than the D3, which puts it into a different market segment. 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.
Sensor comparison: Nikon D3 vs Sony A77 II
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. 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 D3 features a full frame sensor and the Sony A77 II an APS-C sensor. The sensor area in the A77 II is 57 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Despite having a smaller sensor, the A77 II offers a higher resolution of 24 megapixels, compared with 12.1 MP of the D3. 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 3.91μm versus 8.43μm for the D3). However, it should be noted that the A77 II is much more recent (by 6 years and 8 months) than the D3, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The resolution advantage of the Sony A77 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A77 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 D3 are 21.3 x 14.2 inch or 54.1 x 36 cm for good quality, 17 x 11.3 inch or 43.2 x 28.8 cm for very good quality, and 14.2 x 9.4 inch or 36 x 24 cm for excellent quality prints.
The Nikon D3 has a native sensitivity range from ISO 200 to ISO 6400, which can be extended to ISO 100-25600. The corresponding ISO settings for the Sony Alpha SLT-A77 II are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-51200.
For many cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The A77 II indeed provides for movie recording, while the D3 does not. The highest resolution format that the A77 II can use is 1080/60p.
Feature comparison: Nikon D3 vs Sony A77 II
Beyond body and sensor, cameras can and do differ across a range of features. For example, the A77 II has an electronic viewfinder (2359k dots), while the D3 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 viewfinders of both cameras offer the same field of view (100%), but the viewfinder of the A77 II has a higher magnification than the one of the D3 (0.73x vs 0.70x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Nikon D3 and Sony A77 II along with similar information for a selection of comparators.

One feature that differentiates the A77 II and the D3 is in-body image stabilization (IBIS). The A77 II reduces the risk of handshake-induced blur with all attached lenses, while the D3 has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.The A77 II has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the D3 does not have a selfie-screen.
The Nikon D3 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 D3 writes its imaging data to Compact Flash cards, while the A77 II uses SDXC or Memory Stick PRO Duo cards. The D3 features dual card slots, which can be very useful in case a memory card fails. In contrast, the A77 II only has one slot.
Connectivity comparison: Nikon D3 vs Sony A77 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. The table below provides an overview of the connectivity of the Nikon D3 and Sony Alpha SLT-A77 II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A77 II offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the D3 does not offer wifi capability.
Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.
The A77 II is a recent model that features in the current product line-up of Sony. In contrast, the D3 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the D3 was succeeded by the Nikon D4. 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.
Review summary: Nikon D3 vs Sony A77 II
So what is the bottom line? Is the Nikon D3 better than the Sony A77 II or vice versa? A synthesis of the relative strong points of each of the models is listed below.

If the count of relative strengths (bullet points above) is taken as a measure, the A77 II is the clear winner of the contest (15 : 6 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 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 D3 and the Sony A77 II place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing 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 incomplete and does no justice, for example, to the way the D3 or the A77 II perform in practice. 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.
Expert reviews: Nikon D3 vs Sony A77 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 assessments were made in relation to similar cameras of the same technological generation. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
