Dat is een moeilijke vraag...
De nikon is geen erg snelle focusseraar, dus dan zou je eerder naar de nieuwe Tamron kijken. Echter volgens DPreview:

"The big problem with this lens, however, lies in the focusing systems. The autofocus motor is relatively slow and noisy, which puts it at a major disadvantage compared to its ultrasonic motor-equipped competitors, simply because AF performance impacts strongly on many of the typical uses for a fast telezoom lens. The slow speed of the motor means focus tracking simply isn't fast enough for sports or action, or even children running around playing; it's also a distinct problem in low light or with low-contrast subjects, where the lens can take what feels like an eternity to achieve focus. This is compounded by the noise the motor makes, which could be a real problem in situations such as wedding or event photography for which the user wishes to remain unobtrusive; discrete it is not. Also the Tamron lacks a focus limiter switch, so has a tendency to hunt back and forwards through its entire range when it fails to lock focus first time. But perhaps the biggest problem we encountered was a tendency for the lens to mis-focus, seemingly at random and disturbingly frequently, such that F2.8 shots in particular were often not critically sharp (although it must be pointed out that this may be specific to either our test sample, or the Canon mount version)."
En dan heb je met de Nikon wel een focus limit switch.
In dat soort gevallen kan je eigenlijk alleen maar de lens in je handen nemen en er mee spelen...
