The Phoblographer is doing rolling reviews, meaning that many products get a first look that is updated over time. The full review of the Sony 70-200mm f/2.8 GM OSS G Master has just been completed.
In the review, The Phoblographer's Chris Gampat writes, “When you consider a camera system, one of the most important lenses to look out for is a 70-200mm equivalent–and Sony has been working on delivering that in the form of the Sony 70-200mm f2.8 OSS G Master lens for full frame E mount cameras. With weather sealing, a white body, 18 groups with 23 lens elements, and a constant f2.8 aperture throughout the zoom range coupled with a small size overall–there is a lot of love about this lens.”
Gampat also describes his preferred image quality tests and how this lens fared in those conditions. "My favorite way to test image quality is in the studio or in a studio setting. It’s where I’m most comfortable. Despite the fact that I prefer to work with small, light prime lenses, the 70-200mm f2.8 GM OSS is rather nice to use and delivers very solid image quality." And he continues, "Since I believe that the best sharpness from a lens comes out when you use a flash, I did just that. The sharpness from this lens is impeccable when the subject is nailed perfectly in focus."
