No they don't - they simply state that on a couple of lenses a filter will help with weather sealing.

That's all.

The phrase "Canon approves" is meaningless..

They don't say 'help' they say 'complete'.

But you are free to go sans filter as you like.

If you want to be pedantic about it, they don't use the phrase "weather proof" either..

Completeling the weather sealing of a scant number of lenses is not remotely related to protecting the front element from scratches and blunt impacts.

They definitely use the word "complete".
I think your point is bang on though, it is a small percentage of lenses that Canon state filter is required to complete the sealing.
Further, they do state in EF Lens work III that a flat protection filter is problematic. Specifically in the section where they explain the reason for Meniscus protective front elements. While they do not state it, the drawings of the lens indicate 300 f4 L IS is the only lens with a non meniscus front element.

It is to each his own as this debate will never end. But the real fact that remains with all the filter pooh-pooh'ers is, they think once a filter is screwed on to a lens it can not be removed. It is as stuck as ugly on an ape. The truth is they screw off just as easily as they went on.

I am a protective filter user. I am also a filter remover. Most of the time it is on the lens.
In 40 years of professional life no one has come to me and said, "That is a great photo if only you had not used that protective filter!"

Since this debate will never end I am going to bow out. Thanx for your thoughts.

I don't think there's a single person that thinks that...

I am a filter "pooh-pooher", and I do not think that filters cannot be removed.

Hence, I think that your statement is incorrect because you used the word "all".

If you want your statement to be an actual fact, then you may want to replace the word "all" with "many", or "most". Or at least qualify the statement by adding a phrase such as, "in my opinion", or "I think that".

.


"Your" and "you're" are different words with completely different meanings - please use the correct one.
"They're", "their", and "there" are different words with completely different meanings - please use the correct one.
"Fare" and "fair" are different words with completely different meanings - please use the correct one. The proper expression is "moot point", NOT "mute point".
