Sony Alpha 7R II Review

Like me you may be a bit confused by the very many Sony A 7 cameras, there seems to be many versions and understanding why and which you might want is a bit of a struggle. This review on the ever helpful DP Review might help you with the Sony Alpha 7R II

Intro-001

The Sony a7R II is a 42MP full frame mirrorless camera with 5-axis image stabilization, featuring the world’s first (and currently only) 35mm BSI CMOS sensor, and including a hybrid autofocus system and 4K video capabilities. It’s the fifth in the company’s a7 range of full frame cameras and the second high-resolution ‘R’ model. However, although its name and appearance are very similar to the first round of a7s, the R II arguably represents just as significant a step forwards as those first full frame mirrorless models did.

The reasons for suggesting this are two-fold. Although the a7R II’s body is essentially the same as that of the 24MP a7 II (albeit with more substantial magnesium alloy construction), the camera includes two significant changes:

The first is that this is the first full frame camera to feature a sensor based on BSI CMOS technology. Although Sony always stressed that the benefits of BSI designs are most valuable in small sensors, its application on larger scales should reduce the pixel-level disadvantages of moving to higher pixel counts (which means an improvement in quality when viewed at a standard output size).

Secondly, and perhaps, most unexpectedly: the camera’s phase-detection autofocus capabilities have been increased to the point that it not only focuses quickly and effectively with its own lenses but can also do so with lenses designed for other systems. This may not sound like a big deal until you think about what Sony needs to do to make the camera a success: win-over dedicated photographers, many of whom are already committed to other systems.
