Lens Weather Sealing Question

On WR pentax lenses there is no asterisk about using a front filter to complete the seal. Many of Canon's L lenses do say a filter is necessary to complete the weather sealing...what is the design change here that makes a filter necessary for canon but not Pentax lenses?

I think Pentax WR lenses have a seal around the front element.

This thread is definitely relevant to the Pentaxians who use their system (lens+ camera) in 'difficult' conditions. Herein difficult may encompass splashes, rainstorms, mud, salt, wave spray, dust ..... I am among this group and I use a lot my system in foul weather incl. subtropical rainstorm, storms on beaches, mangroves, ... has an interesting article on 'weather resistance' at :
www_dpreview_com/articles/3864522077/survival-of-the-fittest-weatherproof-splashproof-waterproof-et-al (Replace '_' by '.' to access the link.)

The article is eye-opening IMHO on the lack of standards in the industry and the very vague definition(s):
" definitions vary from brand to brand"

"It's very confusing, and all the more so as it's the users who really get to test this stuff"

I would add that the concept of WR is a relatively newer marketing tool, and that many older lenses were not labelled. This is relevant to our Pentaxaxain community who has a collection of vintage lenses still useable on modern dSLRs.

Unless your camera and lens system is rated waterproof, dustproof or even shockproof, the notion of WR is subjective. It remains up to the users (IMO) to read reports and discussions in a forum such as PF.

Food for thoughts....

I brought my K7 and 50-200 WR down to the lake with me during a trip in the summer. Got splashed plenty of times, and nothing happened to it.
