They tested the auto focus speed of Sony Alpha a7RII with Sony FE 70-200, A-mount 70-200 f/2.8, EF 70-200mm f/4L IS USM lenses. They also tried the leaked Nikon F-mount to Sony E-mount lens adapter on Sony a7RII, and confirmed this adapter will be announced soon.

Nikon has announced a new DX lens AF-S DX NIKKOR 16-80mm f/2.8-4E ED VR lens (Sample Images) today. Designed to provide an enthusiast photographer with a wide range of options. Covering a 24-120mm equivalent range on Nikon’s APS-C bodies, it offers Nano Crystal Coating and an electromagnetic diaphragm for the first time in a DX lens. The latter feature gives the lens more reliable control over exposure during high speed shooting.
Along with new AF-S DX NIKKOR 16-80mm f/2.8-4E ED VR lens, Nikon also announced two super telephoto prime lenses today: AF-S NIKKOR 500mm f/4E FL ED VR (Sample Images)and AF-S NIKKOR 600mm f/4E FL ED VR (Sample Images). Both are significantly lighter than the versions that preceded them and each use an electromagnetic diaphragm for more consistent exposure control during burst shooting. The Nikkor 500mm F4E weighs 6.8 lbs/3090 g as compared to 8.5 lb/3880 g of its predecessor, and includes three Extra Low Dispersion elements. The 600mm F4E is 3.2 lb/1450 g lighter than the preceding model, weighing 8.3 lb/3810 g. Both lenses use Nikon’s Nano Crystal Coating, two fluorite elements and VR rated to 4 stops of stabilization.
