Sony caused a major stir in the photographic world when it introduced the 24MPhường Alpha A7 và 36MPhường Alpha A7R, because they were the first mirrorless cameras lớn have full-frame sensors – the same form size as a 35milimet film frame.


Altrộn A7 III - one of our favorite cameras right now. There"s a number of improvements on the new mã sản phẩm, with an all-new sensor & highly sophisticated 693-point AF system, while handling and performance has been improved also. However, the Alpha A7 II is still a great buy and can be found at heavily discounted prices, making it a very tempting proposition.>

What"s more, these two cameras (subsequently joined by the 12MP. Sony Altrộn A7S) are incredibly small for full-frame cameras, not too dissimilar in kích thước khổng lồ the Micro Four Thirds Olympus OM-D E-M1, and offer a similar cấp độ of control.

Now Sony has created new waves of excitement by introducing an update to lớn the A7 in the guise of the Alpha A7 II. However, some may feel that changes are rather small as, lượt thích the vast majority of the new camera"s components, the sensor is the same full-frame (35.8 x 23.9mm) 24MP Exmor CMOS device as is used in the original Altrộn A7.

The biggest news about the Altrộn A7 II is that it"s Sony"s first full-frame compact system camera to feature in-body stabilisation. This means that the sensor can move sầu to lớn correct for accidental camera movements during the exposure. This 5-axis in-camera image stabilization may be unlikely to tempt existing A7 users to lớn nâng cấp, but it does make the new camera more attractive than the older Mã Sản Phẩm to lớn new buyers.

The stabilization corrects X and Y axis movements as well as pitch, roll and yaw for both still và movie recording. When a stabilised Sony lens is used on the camera the two systems combine to give optimised performance, choosing the best one lớn use for the focal length và each type of correction. The stabilization effect is optimised, but not cumulative sầu, as one or the other system is used, not both.

Helpfully, those using older (or third party) lenses that cannot communicate with the camera can input đầu vào the focal length manually lớn use the in-camera stabilization system.

It"s probably worth reminding ourselves at this point that the Sony A7 series uses Sony"s E-mount. This means that these full-frame cameras can accept both full-frame & APS-C format E-mount lenses, but the image kích thước is reduced when APS-C lenses are used. Altrộn mount optics made for Sony"s DSLRs và SLT cameras can be used via an adaptor. There are also adaptors available khổng lồ allow Canon and Nikon lenses to lớn be used.
