Sony Alpha 7S review – Design
In terms of the major design differences between the A7S and the other pair of A7 models, there really aren’t that many, if any at all.
The A7S sports the same magnesium alloy shell as seen on the A7R, meaning that its both dust and weather-sealed and as such is well suited against the weather you might encounter out in the field.
In terms of the camera’s controls, the A7S sports the same alignment of a pair of control dials on conjunction with a rear scroll wheel.
This arrangement works well enough, although it’s not quite as impressive as that found on some other CSCs, including the Fujifilm X-T1.
One of the only major design differences for the A7S is present underneath the camera’s bonnet. The model now features an all-new electronic shutter setting as an answer to criticism about how noisy the shutter was on the other two A7 models.
This new electronic shutter mode is completely silent, and as such is perfect for when one might be required to take discreet photographs.
One issue here is that there’s a slight delay between pressing the shutter and capturing the image, and as such it’s not always suitable for moving subjects, however for static subjects where you might need to keep the noise down it’s perfect and very much welcomed.
