Which UV/Skylight filter for my 20D kit lens, 18-55

I have been using either Tiffen or Hoya Skylight B filters on my other lenses. Fortunately, I have 3 lenses that are 58 mm so I could interchange, but what a nuisance. I do switch when I want the circular polarizer since it is more pricey.

What I'm wondering is since this is a wide angle lens made especially for the SLR digital line, does it require a special filter?

I would suggest that you get a good lens hood and, for the most part, forget the filter. Use one (which you already own) if you are going to shoot in really bad conditions like in the wind at the beach, etc. The hood will give you the mechanical protection you are looking for and, in addition, help to prevent problems from strong light sources just outside your picture area.

If you insist on getting a filter, you might want a thinner-than-normal filter for the wide angle lens settings to avoid vignetting (darkening around the corners).

As a good uv filter can cost more than that lens, it is probably a good idea to give it a miss. Replace the lens as necessary!

:D Only joking really – the price of good uv filters is the real problem. In reality, it's not really necessary if you look after your kit (and by the very nature of the question, I guess you do).

Well I bought the little lens hood that Canon makes for this lens, but it's not too impressive.

Thanks for the advice about the filters.

Hi Olivia. If you do decide to get a filter you shouldn't need one of the very thin (and most expensive) filters because it's only a moderate wide-angle thanks to the 20D sensor size. I only have a polariser for my kit lens.

I too got the hood and think it is less effective when I have a filter installed because the filter puts the final piece of glass further out and hence more likey to cause flare. So I agree with the others.

I would not bother Olivia sorry. If you have a lens hood that will give you some protection.

I can't believe everyone is telling Olivia to diss the UV filter... Suppose your out with your camera and you've only got the hood on your lens. While your walking, you accidently get a little too close to a tree branch, which makes contact with your front element and deeply scratches it. Replacing that lens new from B&H will set you back $140, a new UV filter is $20.
