lets start with the Zeiss 50mm 1.4 SSM ZA,
incredibly fast af, no hesitation, a little better then the Sigma 50mm 1.4 DG, which is known for fast af speed when compared to other high speed 50mm optics. The Zeiss 50mm f1.4 ZA, almost identical in size to the Sigma 50mm 1.4 DG, a bit heavier, produces beautiful bokeh (better then the Sigma. It appears the focal length is longer on the Zeiss or the Sigma is not a real 50mm), no need to sell it.
The Zeiss 24mm f2 SSM, a heavy lens, if you already own it, keep it, af performance on the Sony A7rII with the LA EA3 is stellar.
The Zeiss 24-70mm f2.8 SSM also works flawlessly, super fast, no hesitation.
The Zeiss 16-35mm f2.8 SSM, another amazing piece of glass, although large and heavy, works perfectly.
These Zeiss/Sony lenses in alpha mount are known for extremely fast af performance when compared to Nikon and Canon, the A7rII takes full advantage of it.
