I would not use this lens for anything else than @ f1.4 (or in exceptional cases f2, where needed), as I consider it rather a f1.4 lens, than a 105mm lens
A joy to use wide open. No comparison to the AFS 85mm/1.4G.
With the D5, AF is sufficient fast to capture my running dog. More importantly, the AF is very precise with the D5. I have more issues with the D4/D800 to get repeatable results.
