Sony A77 II, we have tested it

Sony A77 II

The Sony A77 II is Sony's bet on translucent mirror cameras . With a robust and ergonomic body , the Sony A77 II features translucent mirror technology that offers very fast shooting speed and focus. It has a 24.3 megapixel CMOS sensor, accompanied by a BIONZ X processor that allows a very fast shooting speed and minimizes noise. The camera can shoot up to 12 images per second with continuous focus on, so not a single detail is missed. The focus is undoubtedly one of the star features of the Sony A77 II.79 zones, to be said soon. Includes an electronic viewfinder and flip-up screen. On paper the Sony A77 II is a super camera, let's see how it performs in practice.

Design and handling

The Sony A77 II has a robust design (magnesium alloy) that reminds us of any high-end SLR camera . It is comfortable to hold,  it would be good to lose a few grams (647 grams only the body). The controls are very well located so that we can reach them without difficulty. In the upper right is the power switch, the trigger and a wheel to adjust the speed . There is also a small screen to view the parameters of the shot and other buttons to adjust theISO sensitivity, exposure compensation, white balance and the capture mode (single, burst, timer ...). At the top left is the selection dial for shooting modes (automatic, manual, scenes, video…). This wheel is a bit uncomfortable to handle since, in order to turn it, you have to press the button located in the center.

If we go to the rear we find a wheel to adjust the opening, positioned so that we can handle it with the thumb, while the index finger reaches the front wheel (speed) without problems. There is also the video button , focus mode, display mode, button function and crosshead to move through menus. The memory card is inserted from the right side. On the left side are the connections , all covered by their corresponding cover, which by the way fit well and are easy to open. It has an output for a microphone, connector for external flash , direct current input, microHDMI and microUSB . The lens used for the test is a 16-50 millimeter zoom with f / 2.8 aperture. It has a switch to lock the ring , very practical when it comes to storage.

Screen and viewfinder

The Sony A77 II allows us to shoot through the viewfinder or its rear screen. The electronic viewfinder has a good resolution and shows us the information of the shot. The screen is not tactile, but it is very versatile since it allows us several positions. When we save it, the screen can be closed and it is totally protected. It measures three inches diagonally, a large enough size to be able to see the frame clearly. It looks pretty good in the sunlight. In addition, being foldable allows us to find the best angle so that there are no reflections. Has a proximity sensorthat turns off the screen when we bring the camera close to our face, and at the same time connects the viewfinder, so it does not use more battery than necessary.

Focus and shoot

As we have already said, the 79-zone focus is the standout feature of the Sony A77 II. The translucent mirror system allows you to focus very quickly, even on moving subjects. Behaves equally well when video recording and is very quiet thanks to the engine included in the lens.

Another advantage of the translucent mirror is the speed of burst shooting. The Sony A77 II shoots up to 12 photos per second with continuous focus mode on. The limit is 60 shots if we are working in JPEG format , which is not bad at all. The BIONZ X processor also takes care of processing the data quickly. Without a doubt, speed is the strong point of the Sony A77 II.

Picture quality

The Sony A77 II has a wide and very bright sensor , the same one that we find in other models like the a6000 . It manages to capture with a great level of detail and the images are very wide, so we can work with them at a professional level without any problem. In the image gallery you can see the sharpness it achieves, even in low light conditions. The BIONZ processor promises to reduce noise at high sensitivities , although above 6,400 ISO the noise is already more than evident, so it is better to try to maintain a somewhat more moderate level. Also keep in mind thatthe lens plays a very important role in this section and the quality will vary depending on the model we are using. Videos also have a good level of detail and the autofocus responds very quickly and accurately. It also includes a stabilizer built into the camera, to reduce shake.

The  Sony A77 II is a worthy successor to the A77 launched three years ago. Keeps the mirror translucent and boosts speed, both when focusing and shooting. These two characteristics point directly to sports or nature photography , where speed is necessary if we want to capture every last detail. Both the viewfinder and the screen have good resolution and their combination is very comfortable to work with. The screen is especially practical when recording videosor shoot at slightly complicated angles, as it allows us to adjust it to the most appropriate position. As in its predecessor, the image quality is still outstanding, but be careful with raising the ISO too much or we can load the photo with the annoying noise. It has a good variety of connections , especially the WiFi and NFC to be able to send them directly to our smartphone.
