Then someone else would complain about lack of weatherproof… To me, the lenses are not that fast to reduce their transmission with filters. f/5…6.3 is very close to the limit of most AF sensors, isn't it? And a protection filter in a slot is pointless.

 

So I would be the one asking them to make at least one without more than the usual holes in the tube.

 

Of course, one could focus without the filter and get a second filter holder to change quickly. But as the better one is a "Sport" candidate, that would be a bit annoying, wouldn't it?

 

EDIT: Another question would be where to place the slot?

 



It looks already pretty packed. Close to the camera there's the clamp and left of it the AF section starts. Left of it OS and left of that the zoom ring and underneath the space for the extension tube. I don't see a cheap and effective spot for such an item. I guess, the extension tube needs all the space to the AF-switch section
