I have the digital Rebel with the lens kit as well as a 50 lens and a 70-300 lens. What filter(s) would be the best for these lenses? I mostly shoot sports (football, basketball, baseball, volleyball, wrestling).

About the only two filters that have much use in digital photography would be a protective glass(or UV) filter and a circular polarizer for cutting glare from water, glass, and shining painted surfaces. Most other filtering can be accomplished in a photo editor program.

Graduated ND filters are beneficial for controlling strong contrasting light and reducing light input to achieve slower shutter speeds.

A polarizer (circular) is a should have.

The UV filter for protection is one of those that is hotly debated and a personal choice as to whether you use one or not.

Well, the kit lens will take a 58mm filter. Not sure about the others. However, the filter size will be clearly marked on the lens somewhere..usually around the front glass.

Here is more info about what a lens can tell you....

I will use the Canon kit lens as an example.

1. a circle with a diagonal line going through it followed with a number 58mm...this is your filter size for the lens.

2. 18-55mm.....this is your focal range of the lens. With the DRebel 1.6 cropping factor, this turns into a 29-93mm lens. Gives you a nice wide angle to low telephoto.

3. 1:3.5-5.6.....this is your lens speed, or aperture. The lower the number, the more light is transmitted to the film plane, or sensor plane. The higher the number, the less light is allowed. If you look at lens specs often, you will note that faster lens tend to be bigger, heavier, and more expensive. The kit lens has an aperture value of 3.5 in the wide angle or low end, to 5.6 fully extended in the telephoto end. Some zooms will have the same speed throughout its range..and these tend to be more expensive.
