We knew that Sony’s new A7S would be a low-light monster. We knew it would provide outstanding image quality due to its super large pixels. We knew that it would put pretty much any other full-frame camera to shame. What we didn’t know is that it would even rival medium format systems in terms of pure image quality. Or at least, that is what Michael Reichmann with The Luminous Landscape claims.
Reichmann has just posted his first-impressions review of Sony’s new 4K-capable full-frame mirrorless camera, and he seems to be quite smitten with the product. Thanks to its large pixels, which are twice the size as those of the A7, and three times the size as those of the A7R, the camera produces not only super clean high ISO images, but also renders a certain look that Reichmann likens to that of medium format cameras.
Compared to the 36MP A7R, Reichmann finds that the A7S produces superior images at ISO settings beyond 1,600. And while the A7R’s output becomes pretty much unusable (in his opinion) at ISO 12,800, the A7S holds up well until ISO 51,200 “with some moderate noise reduction.” As for dynamic range, Reichmann claims he does not see a difference between the A7S and A7R, but admits that this may need further testing.
Another aspects that he likes about the camera, apart from the possibility to record 4K video, is its electronic front curtain shutter, which helps make the camera virtually silent during exposure. This is something that wedding photographers, among others, might find to be a great benefit, as it helps take pictures more stealthily.
After reading Reichmann’s first impressions over at The Luminous Landscape, we can hardly wait until our own review unit comes in and we can put it through its paces.
