“The line is always there, but it is very hard to see. There is an opaque
piece of plastic behind the main mirror. It has several functions, but the
main one is to act as a support for the mirror. It is how the sub-mirror (3)
in the diagram hangs/pivots from the main mirror (2) in the diagram. The
cutout allows rays of light to pass through the main mirror to the phase-
detect AF sensor (7). When the mirror raises, the sub mirror simultaneously
pivots to contact the piece of plastic behind the main mirror (so they are
parallel on the roof of the mirror box). Unfortunately, Canon doesn’t sell
the mirror by itself (only the mirror box as a complete unit), or I’d show
you a picture.”
我收到的两台新的6D,和一台refurb的都是这样，大家可以安了。 |
