Canon recommend using a UV/protection filter on their lens

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

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

no. Because the threads are so fine that unless you submerge the lens under water at a high pressure for a while, i don't think any water would go past the filter thread. But WAY before that the camera that u use will already be having heavy water damage .

Thanks. I've seen those little holes before and never knew what they were for.

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.

if i invest thousands in a good lens, i want to see that in my images. if i damage my front element, i'll get it replaced, or replace the lens with a newer better one.

Hmmmm, 'Consider using a UV....." doesn't really sound like a recommendation, more a suggestion. Certainly not as definite as 'I would remove all filters for maximum optical performance' or 'ANY and ALL UV/protection filters have some degree of negative impact on image quality.'

Mr Misinformation has revisited the thread. You're selective quoting.........

On short lens (200mm or less) you will not see any degrading other than ghosting with point light sources in rare instances.
Your theory sounds good, but in practice it leaves a mess if you shoot where I do...
