Trapdoor on lens hoods

Hi, I'm new to Pentax digital. Years ago I owned a Pentax ME film camera but started out my digital photography with Nikon.
I have a question right out of the gate and I must say I love the camera, a K3 with an 18-135 lens but the owners manual doesn't help much. I wish David Busch would write a book on the K3.
My question, what it the small door like opening in the lens hood for?
Thanks

So you can adjust filters without removing the hood.

Apparently, Pentax has a patent on it from 2005. So, it will be awhile until Canon and Nikon can follow suit - like a bit over 7 more years......... I did not read the entire patent - just the short web description.

Welcome to the forum, it's so you can turn your polariser filter with the hood still on.

One can move the circular polariser around, a bit, through that hole, but not much. That's why I put the hood on the lens after I set the filter at the wanted position.

Thanks everyone. I'd never have figured that out on my own. Sounds like a typical innovative Pentax idea.

Does anyone have a suggested book I could buy for the K3? I had a couple of excellent David Busch books for my Nikons but I can't find anything similar for the K3

Yvon Bourque has one for the K-3 here:

Pentax K-3 e-book

I bought his book for the K-30 when I got my camera and found it much easier to read than the original manual and hence got up to speed with the controls and functions more quickly.
