The Sony SLT-A77 II is, as its name suggests, an updated version of the original A77 camera that was released in 2011. The A77 Mark II has a new autofocus sensor, and it is far more than just an updated version of an existing design than its predecessor. Instead, the A77 II is based on the autofocus module, which has 79 focus points, making it the camera with the most focus points available on the market. These points cover a very large portion of the frame. Additionally, it is rated to perform in illumination conditions as dim as -2EV. Although this does not necessarily make it as advanced as professional DSLR cameras because such cameras have more cross and diagonal sensor components, it looks quite remarkable for a camera that is priced in this segment of the market.
A appealing feature set is provided by the camera because of its focusing capabilities as well as its capacity to capture photographs at a rate of 12 frames per second. The A77 II further benefits from the autofocus tracking advancements that have been featured on recent Sony cameras. These advancements make use of information from the primary image sensor to identify and follow a particular object.

In addition to the autofocus sensor, the A77 II receives an upgraded 24MP sensor (which is presumed to be a version of the sensor found in the a6000, but without the on-chip sensor phase detection design) and all of the advantages that the company has made available through the introduction of its Bionz X processor. This implies that it receives three new features as a result: diffraction reduction technology, context-sensitive noise reduction, and more intelligent sharpening.
Although Sony emphasizes that the A77 II should not be compared to professional-grade cameras (not least because it is much less expensive), it is starting to gain the kinds of specifications that – at least on paper – suggest it could be capable of punching significantly above its weight. Although Sony stresses that the A77 II should not be compared to professional-grade cameras (not least because it is much less expensive), For example, the enhancements made to the autofocus technology of the A77 II go much beyond just the focus sensor itself.
A wide variety of subject identification technologies that Sony has launched in recent generations are incorporated within the Mark II. As a result, it provides Eye-AF in addition to traditional face detection capabilities. It also receives the most powerful version of the autofocus mode known as “Lock-On AF” that we have seen so far. This mode will either employ or let you to pick an off-center beginning AF point (previously most Sonys assumed your subject was the thing at the center of the frame, when you started tracking).
The A99 made use of its on-sensor phase detection components to follow the movement of a subject when it was in between the focus sensor’s focus points; however, the A77 II makes use of the focus points that are next to the point that is now active. In addition to this, the A77 II is the first Sony camera to provide users the ability to select how tenaciously the camera should remain with the current focus point. This is the kind of feature that one would typically only anticipate finding on extremely high level models. Even better, it allows you to choose distinct parameters for video and still photography shooting respectively.
In addition to this, the camera has a distance limiter that is modeled after the one found on the A99. This feature allows you to specify the approximate range of focus distance over which you expect your subject to travel. This is done to prevent the camera from becoming distracted by subjects that are either close or far away. Another new feature is the ability to choose whether the camera should prioritize the shutter release or the focus while taking continuous shots. This provides a significant increase in the amount of control the user has over the way the camera behaves when shooting continuously. Overall, the A77 II is a significant advancement for Sony in terms of its ability to adjust autofocus.
It is interesting to note that Sony’s marketing for the A77 II seems to imply that the company is moving away from the label “Single Lens Translucent” and instead using the phrase “Translucent mirror DSLR.” This is a little terrible phrase to use in terms of semantics, but mainly because the mirror is really semi-transparent (translucence generally suggests a diffuse image): the camera contains all of the features that are referred to when using the term ‘DSLR.’
A quick aside: although many individuals are under the impression that the term “reflex” in the term “Single Lens Reflex” refers to a movement that is performed by the mirror in a reflexive manner, this assumption is incorrect. In this sense, it refers to a reflection; hence, a camera like the A77, which has a mirror that does not move, is nevertheless considered an SLR.
The technique is the same as it was in the past. There is a fixed mirror that is only partially transparent that directs a portion of the light up to a dedicated focusing sensor, while the remainder of the light goes through to the main image sensor. The focusing feature is accessible at all times, including while recording videos, despite the fact that some light is being diverted away from the autofocus sensor. This has a minimal impact on the image quality at high ISO, but it eliminates the need for the complexity of several rotating mirrors.

Those who are interested in professional-grade photography and autofocus speeds but don’t want to pay professional-grade rates need go no further than the Sony a77 II. Because it does not have a movable mirror, the a77 II has a significant advantage over many of its DSLR competitors in that it is able to employ continuous AF effectively during both 12 fps bursts and video shooting. Additionally, in-body image stabilization makes it possible to shoot both still images and video with a degree of steadiness that is unmatched by the competitors. Unfortunately, subject tracking, which was one of the most anticipated aspects of the a77 II, does not have a particularly high degree of reliability. In addition to this, pictures taken with a high ISO typically include a lot of noise. The build quality and ergonomics, on the other hand, are excellent. In general, the a77 II is a highly capable camera that can be purchased at a very affordable price.
