Lumix GM1 vs Nikon 1 J1 autofocus during video comparison

More info: m43photo.blogsp...
Lenses used: Lumix G 14mm f/2.5 (used at f/2.8) and Nikon 1 10mm f/2.8 (used at f/2.8).
The ISO was set to 200, except when specified to 1600 in the video.
As you see, the Nikon 1 J1, despite being two years older and cheaper, is way better in terms of acquiring focus. Even when panning quickly, it gets the focus right almost instantaneously, and even in poor light and high ISO.
I would say that Nikon is the only company which got PDAF for mirrorless cameras right from the beginning. The AF performance is just amazing.
Now, these videos are not typical of how people normally use video, but they illustrate the strength of the Nikon 1 system. Also, the 27mm equivalent wide angle pancake is not the one which needs fast AF the most.
However, with the recently launched Nikon 1 70-300mm f/4-5.6 lens, the Nikon 1 system will be the first to be useful for birders.
At no time before has there been a so small and light interchangeable lens system with this reach: More than 800mm eqvivalent. And with the fantastic AF performance of the system, this lens should be useful for catching birds in flight (BIF). Especially with a camera like the Nikon 1 V3, which has a proper grip and EVF.

J1 is much faster and smoother.

Yes, it was the first mirrorless camera to implement on-sensor PDAF successfully.

Fredrik Gløckner I have nikon d5300 and af in liveview isnt great. Don't know why Nikon isn't using this technology in their Dslrs.
