dumb question about lens hoods

I feel really dumb asking this, but I couldn't find it on here or anywhere else. My lens hoods have this tab near the mount. What's it for?

If its the removable piece, its to allow you to use a polarizing filter.

Do you mean the little slide out panel that allows you to adjust a polarizing filter with the hood on?

That small tab is what makes Pentax hoods so much better than the rest. They are there to manipulate a circular polarizer without having to remove the whole hood. It is sheer brilliance.

Edit: holy crap you are fast !

Thanks guys. It seemed liked it would have something to do with the filters, but since I don't have/use polarizing filters, I didn'teven think about that

The lens was designed to have that so that the other camera brands would be jealous with the reason that why didn't they think of that! ..and it was such an easy and brilliant solution!
All the other brands are actually keeping their pride by not copying it (..not unless it is patented by Pentax and they really can't incorporate it into their lens even if they wanted to!).

I always thought it was so that you'd go nuts trying to find another one having lost the original, finally giving up and shelling out $65 and buying a complete replacement hood from Pentax, thereby improving Hoya's bottom line. More niggly little parts = greater profit potential.

It really is a nifty little feature, but I can remember when a lens hood screwed or clipped onto the filter itself, thus rotating the hood rotated the polarizer as well, making the use of niggly little parts unnecessary.

I like how you can use a polarizing filter without taking off the clip, but I almost lost it TWICE. At least better than Canon's solution of taking the entire hood off. At least if you lose the clip it doesn't affect the operation. It just looks more ugly when the hood is on.

For some mysterious reason, I haven't lost mine yet (I've always been adept at losing little niggly bits) but when I do, I'll carry on bravely without it

All you have to do is mount the hood outboard of the filter and just use the hood as a huge-assed handle for turning the filter. Works fine for me.

With my 16-50 I threw the niggly bit into the box and left it. With other lenses and CPLs I use aftermarket hoods and mount the hood after the filter which provides a convenient way to adjust the CPL. Even cheap rubber hoods work for this method.

These guys are all smoking something. The removable tab is so you can get your finger in there to smear the Vaseline around to get that "dreamy soft" look.

Now how does it go..."Can't the Marx Brothers be locked up, or even tortured for all the trouble they've caused?"

oh, i thought it was the Pentax patented "selective flaring system", you can remove the little door to add a little artistic lens flare when needed.
