are polarizing filters a "must have" for taking beach pictures?

Buyer beware. I bought a couple of circular polarizers off of Amazon before. They were name brand, but the price seemed 'right'. I got them and both had imperfections on them. Weren't enough to argue return/replacement but I learned my lesson.

Now this isn't to say I would fault Amazon, either. Heck. I bought the Sigma 28-105 Art lens from them for my Canon 5dMk3.

Great info, guys, thanks!

I'll get a filter for my 17-35mm, and play with it a bit.

FWIW, I use step up/down adapter rings on my other lenses to use my 52 mm Hoya polarizer. The only downside is the adapter ring will not take the lens cap, so I can't just leave it on the lens. A bit of a pain, but I can live with it. Better than having to buy a filter for each lens.

They also make filter stack caps which allow you to screw a cover on the filter.

I have filters on every lens I own for two reasons. One to help with the sun, but most importantly it is cheaper to replace a $5-$25 filter than replace a lens because you scratched the glass.
