The patent does not cover a zoom, only a prime.
But my question is: "Will they discontinue the 16-35mm?" Or will they maintain three wide angle zooms in the lineup?
Hopefully they will replace the 16-35mm in the lineup (with the 14-24mm) and thus be able to lower the price (because it will sell more units at a lower price).
Their claim boils down to this:
[Problem to be solved by the invention]
However, even if the character or sign which shows the position of the surface which forbids touching somewhere in optical elements is described, when garbage and dirt have adhered in the manufacturing process of a lens, since it cannot wipe, it will not be able to be used but productivity will be deteriorated.
Since the garbage or dirt which adhered when the user was doing lens use were not able to be wiped even if it prevents adhesion of garbage and dirt by a manufacturing process, there was problem that it could not be used in the outermost surface of an optical system, at least.
Then, since the object of this invention can be wiped even if garbage and dirt adhere, it is providing the optical system which was excellent in productivity or a user's maintainability, and inhibited generating of harmful light, such as a ghost and the flare.
[Effect of the Invention]
According to the present invention, even if garbage and dirt adhere, the optical system which was excellent in productivity or a user's maintainability since it wiped, and inhibited generating of harmful light, such as a ghost and the flare, can be provided.
