Filters, Polarizers, and Bears, Oh My!

[jeanneholverstott]

I've been reading at length about filters and polarizers. I happen to find the advise and feedback that has been provided by DPS members far more helpful, honest, and objective. So, share your thoughts:
1. Polarizers? Linear or circular? Recommended brands?
2. Other filters? Worth it? Just use the lens hood?
3. Bears, well, not very applicable at this point, so forget I mentioned them!

1. Circular, linear may cause problems with metering.
2. Maybe, depending on what you shoot. If you're shooting landscapes, you'll find filters are a real help.
3. Forget what?

[ElCapitan]

1) Circular
2) As far as filters go for protection, just stick to the lens hood. Filters for other effects such as ND filters can be great though.

I have to agree with Nicole and ElCapitan

Circular is far better and as for other filters... Obviously get a UV filter for every lens if for nothing more than protecting the glass of your very expensive lens. And yes a set of ND filters can do wonders for Landscape shooting especially when capturing moving water such as waterfalls. Also a Graduated ND filter can really help for getting better skies while keeping your ground subject matter well exposed.
