Canon recommend using a UV/protection filter on their lens

I know that it's a divided world with the use of or non use of filters for "protection" but it was interesting to read that Canon recommend using a UV/protection filter on their lens

You prolly don't want to suck in water, and dirt with a lense that is front vented...

Wouldn't it still have to suck past the filter thread though?

Just out of curiosity, where exactly did you see that Canon said this?

OT a little. I thought the L series is suppose to be more weather resistant then the rest of the canon line up.. so... whats with the holes? never knew they vented the lenses

The 16-35L is front vented. A filter completes it's weather sealing.

Gotcha, Thanks for the heads up.

Well, that's a good example of how to take part of the information and use it to spread misinformation. Canon recommend using such a filter on some lenses, only to complete the weather protection. So that recommendation is only applicable if you're using one of those lenses on a weatherproofed camera.

Here's what Chuck Westfall, from Canon, says about filters -

Well the above is a a good example of YOU spreading misinformation.

Consider using a Skylight or UV filter as full-time protection of your lens, shooting your pictures through it and removing it only when you're using another filter for special effect. And of course, don't forget to use your front and rear lens caps!

I am starting to think that this is a controversial topic.

Not really. Those who don't use filters shouldn't be surprised though when they see splintered sun because of marred front elements.

I have 4 damaged or destroyed filters, and not even the slightest bit of damage on any of my front lense elements.
Those filters would have been my front elements... filters are also much easier to clean.

Well, I have no damaged filters because I don't use them, and I also have "not the slightest bit of damage on any of my front lens elements". I do however have several badly banged up lens hoods. Those hoods would have been my front elements if they weren't attached.

Bet I could find marring on many of these "undamaged" lens I hear about that are cleaned at least once a week.
Funny, I use hoods all the time, and they don't look that bad. Not buying your story 100%...
It's very easy to mar even a hard surface and most common grit found on the floor/ground is hard enough to do this.

There are times when filters need to be removed, but never using them isn't a good solution for many who shoot outside.
No reason to cause needless wear and tear for minimum (or no) results, or to save a few dollars when you've invested thousands already.
