This one (G Master) or that one (Sony G F/2.8 OSS II)... I use Sony A7R II and Sony A99! Sony G is an A-Mount, also E-Mount via adapter, but 500 dollars more... I don't know which has better IQ to grap some of those! Pros and cons
The Sony FE 70-200mm f/2.8 GM OSS E-mount Lens has not yet been release, as it is a new item that was recently announced, and is not yet stated to begin shipping until July 29, 2016. As such, I have yet to see any lens testing from reputable testers to compare the optical quality of the two lenses. The newer Sony FE 70-200mm f/2.8 GM OSS E-mount Lens has 11 aperture blades for a more rounded aperture and bokeh (the A-mount lens used 9 blades), and also has more optical elements designed for more correction from aberration and to focus all light at a single point to increase sharpness, and also has a shorter minimum focus distance. The above are the comparisons from the lens' specifications released by Sony. Comparing the MTF chart, the newer Sony FE 70-200mm f/2.8 GM OSS E-mount Lens seems slightly sharper, especially when viewing the corner/edge performance. However, for a comparison in real-world testing, you would have to wait until the lens is released and available for testing.I will add one point; if you are using both A-mount and E-mount cameras, and you only want to have to purchase one lens, then the Sony 70-200mm F2.8 G SSM II would be recommended. While both are good lenses, you may use an adapter to use the A-mount lens on the smaller E-mount, but there is no adapter to use the smaller E-mount lens on the larger A-mount.
