Countermeasures for harmful rays
The TS-E17mm f/4L has a wide angle of view, and the
lens protrudes from the front frame, so it can be
affected by harmful rays. To prevent flare and ghosting,
cutting off the harmful rays entering the lens with a piece
of cardboard is recommended.
Cutting off harmful rays is also recommended for TS-
E24mm f/3.5L II, by using both the hood and the method
used for TS-E17mm f/4L.
