When capturing HD video using a DSLR camera the lens on the camera is currently the weakest link as it doesn’t allow for both zooming and focusing simultaneously.
Nikon are now looking to change this and have filed a patent in Japan for a new lens zoom design that allows it to be controlled manually and through a zoom button on the camera body if required.
The patent describes a single lens that is capable of being zoomed by hand in manual mode or automatically in its movie and video making mode, while simultaneously refocusing.
Its alos rumoured that this new technology might be incorporated in to Nikon’s new mirrorless camera. Either way I am confident Nikon will not wait long to bring this new technology to market.
