Filter for shooting at a swimming pool

I have not used filters much but I have a family event coming up and will be shooting the kids playing in the pool.
Last year I was shooting canon and I ending up with splashes of chlorinated water on the lens and some of the spots were hard to get off.
So this year I am shooting my sony 70-200 f4 and want to make sure I dont end up with the same problem.

What type of filter should I be looking for Clear, UV, CP ?

What is a good brand for the $50.00(ish) range?

Thanks

A CP filter would eliminate a lot of the glare in the pool.

CP is great but adds another level of complexity - plus they take about 1 stop of light (if you are talking indoor action shots).
A good review about clear lenses here: https://www.lensrental​s.com …uv-filters-on-the-market/
I am happy with Hoya HD protectors.

If you limit is $50, just a clear is about as good as your going to get. I agree a circular polarizer would be great, controlling the light, but that is a slower more thoughtful thing you use to make photographs, and a decent one isn't cheap. Perhaps making sure you're using your lens hood could also help splashes from getting on your lens. Or just keep a good soft cloth handy to wipe off spots would be handy... and cheap.

Putting cheap glass on front of an expensive lens is always of dubious value in my opinion.... for what it is worth.

Normally I agree but in this case I would go with either a clear or a CP. Even a cheap clear filter isn't going to have much of an impact unless it's really cheap, like a frosted glass filter. . A CP isn't going to be that hard to deal with unless your moving around a lot and will offer more to improve image quality than detract from it. Personally I would go with a CP but that's me.

And the CP does things you can't really do in LR of PS. So particularly around water, I agree. But for $50? Not sure that's realistic... but I could be wrong.

Took a quick peek at B&H and they have a 72mm CP for $6. I don't know if I would go that cheap, but they are out there.

Yea, don't go that cheap. However, a Tiffen, while not great in the flare department (shouldn't be an issue with a hood on a telephoto), should be just fine for that application. They *might* degrade IQ very slightly at the long end, but you're not going to notice it for what I suspect your use is (i.e. online photos or up to 8x10 prints).

Yeah..... looked at those listings. Was surprised how cheap some of there were, and how many of those cheap ones had very good reviews. Who knew. For shooting images at the pool, a sub $50 one like a Tiffen would probably be a lot better than nothing. The only thing is that it will also get water marks on it and I am curious how well the coatings on the cheaper version hold up to rigorous cleaning. I am hoping I will be pleasantly surprised. The loss of light through the filter shouldn't be a huge issue in an environment like that.

I have 2 CPs, one a
B+W Kaesemann MRC, a pretty decent CP and some generic I received as a toss in when I bought a camera package a while ago and honestly, other than the tint of the glass, both are almost indistinguishable from one another unless I start really zooming in and checking micro-contrast. I almost prefer the color of the cheepy one.

Cheap filters that seem decent in build can indeed hurt IQ in a very noticeable way. I can post an example of a cheap name brand filter vs a better one if someone wants to see. This filter caused me grief on a 70-200 where I thought I had a lens issue until I took the filter off. I later did a comparison to verify the filter was to blame.

I like the higher end Hoya and b+w filters.

Not as well for sure. Also they can be more of a PITA to clean in the field. However, I have found that with a good amount of tapwater and possibly a very small amount of soap, pretty much anything will come off.

I would also do a quick test to make sure the filter is not complete junk. If you can easily see IQ effects, just return it.
