By The saying goes, a good meal is not afraid of night, this sentence is not an exaggeration on Sony A77. From the end of last year, the A77 model and a variety of lenses in front of us shake to and fro. Why the A77 has such a high popularity. Needless to ask, must it sinking 24.3 million pixel sensor. This one fell swoop than including the full rate, including almost all of the camera! At the same time, it also attracted many people including this writer doubt. Such a high pixel density, high-ISO noise control how can we ensure. Do scientific and technological progress really be able to create such a big “miracle” it? Of course, in addition to the CMOS outside, sony A77, as the past four years, Sony in the end, only a single, interchangeable lens camera also has a very significant breakthrough in many places. The magnesium alloy body, 12fps high-speed continuous shooting, 19-point AF system, and first appeared in the series A “full-size shoulder-screen had aroused the concern of each one of us.
First, let us experience the A77 using the magnesium alloy to build a solid body. The first time in four years, Hou Suoni finally launched a sufficient “weight” in the end interchangeable lens camera, the magnesium alloy body with dust, moisture protection performance. Body appearance Sony A77 hang DT 16-50mm/F2.8 lens, +15 million times magnesium alloy shutter + superior dust and water drop capabilities, Sony A77 body appearance, the flash pops up a special way, the newly designed triple dimension of the LCD screen with 920,000 pixel display accuracy. 3.0-inch Xtra Fine LCD LCD screen. This is the Sony yet another revolutionary technological innovation, to subvert the conventional LCD screen upside down or left and right rotation design, the real 360 ° no dead framing.
The sony A77 with up to about 2.36 million effective pixels XGA OLED Tru-Finder electronic viewfinder, the viewfinder screen clear and bright while reducing the ghosting of the picture, and the rapid response of the viewfinder to become a reality, and true to the shooting scene. A55 is a slight delay compared to the EVF viewfinder effect, A77, basic to eliminate visible delay. The viewfinder than the optical viewfinder device thinner thickness and 33.3 ° wide viewing angle, bright comfortable eye of 27 mm from the eyepiece distance and a 100% view rate.
Brought together a number of Sony world’s first “technology, the latest digital single electronic camera, the sony A77, with enhanced high-definition video recording function, compared to the previous generation of products has been further improved. Can be achieved with a phase detection autofocus during shooting high-definition video shooting to achieve 1080 50p recording specifications. P / A / S / M mode, aperture, shutter speed and ISO sensitivity and other parameters of the independent set, you can achieve beautiful bokeh or manual exposure to achieve the required brightness effect. The A77 also provides such as cinematic-like 25p motion picture recording function, a more creative space for dynamic image creation. Above fixed seats, panning shot way to the show, we can see that the performance of the Sony A77 with real-time focus, auto exposure.
The sony A77 low sense of quality to achieve a high standard. ISO50-800 showing a very fine picture of performance. Of course, ISO1600 is still a test of high-pixel camera Kaner. Admittedly A77 in ISO1600, how much appears certain quality attenuation, but overall its fine is almost negligible. A77 using the 24.3 million pixel CMOS can really bring in more detail than ever before, but the so-called mixed progress in high-ISO noise control is not very obvious, the basic and the previous generation of 16 million pixels CMOS is similar level.
Sony A77 has been introduced to break several records, first of all, the A77, the first 24 million pixel APS-C format cameras, half frame camera pixel records to a new level. A77, also doing my part to become the highest pixel camera of the world’s single electric models. Secondly, 12 per second high speed continuous shooting performance, A77 slight advantage over the D3S Nikon (11 frames per second continuous shooting) become on this planet, the continuous shooting speed of the interchangeable lens camera. Secondly, the A77, also equipped with a Global original “can be turnover, 920,000 pixel, 3.0-inch Xtra Fine LCD LCD screen. This is the Sony yet another revolutionary technological innovation, to subvert the conventional LCD screen upside down or left and right rotation design, the real 360 ° no dead framing. With the addition of about 2.36 million effective pixels XGA OLED Tru-Finder electronic viewfinder, so that the player shines.
Through my detailed test, I believe we already have enough in-depth understanding for the A77. Sony A series of interchangeable lens cameras, the A77, is also fully capable of APS-C “to carry the tripod, the leader in the important task. First of all, the A77, is the first 24 million pixel APS-C format camera, half frame camera pixel records to a new level. A77, also doing my part to become the highest pixel camera of the world’s single electric models. Secondly, 12 per second high speed continuous shooting performance, A77 slight advantage over the D3S Nikon (11 frames per second continuous shooting) become on this planet, the continuous shooting speed of the interchangeable lens camera.
Again, the A77, the viewfinder can be said to be a revolutionary change. This machine not only the world’s original “can turnover, 920,000 pixel, 3.0-inch Xtra Fine LCD LCD screen. A77, also using the Tru-Finder electronic viewfinder, an approximately 2.36 million effective pixels XGA OLED device has a huge performance boost compared with 1.44 million pixels of the first generation of single electrical A55 EVF viewfinder.

In some shooting details, Sony A77 do the same to the force. Such as A77 uses a 1920 × 1080 50p AVCHD recording specifications, is almost the highest level of current at the same level interchangeable lens shooting specifications. Secondly, photo effects model can enrich the player’s shooting ideas, to stimulate “impulse” picked up a camera to take pictures.
Sony a77 pros:
- 24.3 million-pixel APS-C flagship single power
- The magnesium alloy body with a good dust and moisture resistance
- Full-size shoulder-screen professional texture manipulation
- 1080 50p AVCHD full HD recording formats
- 12fps high speed continuous shooting
- Electronic first curtain shutter lag to shorten·
Sony a77 cons:
- the manipulation of the reaction rate is slightly delayed
- High sense of control noise needs to be strengthened
