UV Filter is what most on to protect lens.I recommend B+W MRC UV..
They cost mroe than most but you get what you pay for..
Makes no sense , whatsoever, to spend $1500 on al ens, only to put a cheap filter on it. May as well bought a cheap lens to being with, since the image quality is going to be roughly same..
Bottom line, lens is mad eof individual pieces of glass , called Elelments. A lens is only as good as the "Worst" glass element. Generally, that is the filter..
Polarizing filters remove reflections, also gives wonderful blue skies.I had a ton of filters, when I was first beginning.Now I only use the a few..

Since you are just getting into things and don't want to pay nearly as much for filters as you do for your lens, instead of using B&W (which are top of the line German made optics) try using Tiffen which is being used by major motion picture companies in Hollywood..
You would want to have at least the UV to leave on your lens to protect the front ... as well as a circular polarizer (different than the linear) ... which will take away reflections. Best to swap the filters out, i.e., either have your lens wear the UV or CPL ... for information onthe CPL, Nuetral Density and Graduated Nuetral Density see the following link..
I am about to buy the combination:Canon 400d + Canon 70-200L f/2.8 IS ULMand I was wondering which filter I can use with that lens.I just want a general filter to keep always on the lens, mostly toprotect.But if I could get a lens that also works for other purposes, such aseliminating reflections, it would be great.There are so many types and prices, anyone could tell me what's thebest solution?.
I don't use any "protective" filter on any of my lenses except when I am shooting in dusty situations..
But if you want to buy, buy the better ones..

Then save even more money and trade in that L glass for Tiffen-level glass. The lens is only as good as it's weakest component...

You have the lens cap for protection. Best investment you can make is to spend adollar or two on alens cap keeper. I have them on all my lenses. You attach a sticky button to your lens cap which links via a length of elastic to an elastic noose that goes round the body of your lens..
So when I take off the lens cap it dangles beneath the lens and never gets lost. If it gets to be a nuisance e.g on a tripod it is easy to remove..
I have a similar arrangement for the cover of my flash mount..
Filters at best can be the weakest link in terms of glass quality. At worst they cause internal reflections which will degrade the image..
I have UV filters for my walk around lenses but I only put them on in adverse conditions - dust, the beach etc etc..
Your best protection is threefold:Captive lens capA lens hoodA large enough camera bag so there is always space to put down a spare lens..
