Nikon 1 V2 review
Like its predecessor, the Nikon 1 V2 uses a hybrid contrast/phase-detection AF system that is extremely fast. In good light, the V2 seems to focus almost instantly. It is not only one of the fastest focusing compact system cameras I have used, but it also holds its own against a DSLR. The fast speed is undoubtedly the result of exceptionally powerful processing and motors, but perhaps what is more impressive is that the speed makes continuous focusing a genuine possibility, unlike other compact system cameras that tend to hunt a lot.
In low-light conditions with less contrast, the AF does slow down, seemingly because the contrast-detection AF is being used. However, overall, this doesn't hinder performance too much, and the AF is still comparable to other similar cameras.
