650D’s new sensor has phase-detection points
lying between pixels. This allows the camera to continuously focus even when
recording videos.
650D’s
image sensor
EOS 650 recently introduced is Canon’s first
DSLR model that can automatically focus while recording videos. The Japanese
brand has been using contrast detection autofocus before but it appeared not
only bulky and slow but also incapable when recording videos. Another option is
phase detection which seems faster but inactivated in live-view mode requiring
mirror closed.
Latest images about phase detection
discovered by us have revealed some secrets about 650D’s sensor. The most
amazing is phase-detection points are put between pixels in the camera’s
sensor. Some web rumored about this when Canon had registered their relative
patent in 2010.
Phase-detection
points lie among pixels
This type of autofocus is not completely
new. Previously, Fujifilm and Nikon also integrated it into their products:
F300EXR and Nikon Series 1. However, Canon has made some changes for it to be
suitable for DSLR models.
Although there’s no official announcement,
Canonrumors as well as Photographybay all believe Canon will probably put the
technology in their next mirror-less camera. The combination of phase and
contrast detection will give mirror-less cameras to fast and continuous
autofocus even in the process of recording videos.
