Nikon D800 Tests - D800 @ 1000mm: using Sigma 150-500mm w/ Tamron 2.0x Teleconverter.
Best viewed fullscreen: This test was was done with a Nikon D800 @1000mm, using a Sigma 150-500mm w/ Tamron 2.0x Teleconverter. This is not suitable for fast sports or fast moving wildlife, as the AF is basically useless and all focusing must be manual. Although acceptable focus is achievable since wide open is about f13 when used with 2.0x TC. Obviously it required a heavy tripod. At 1/125sec I was able to stop leaf movement in a light breeze and avoid any lens movement at 36mp.
