I was thinking of getting my girl a lens for V-day and came across a bunch of sites saying that a must is a good set of filters for a DSLR. She has a Canon Digital Rebel XT with no lenses other than what came with it. I'm having trouble finding specs on filter size...I assume what I would need is 52mm? Also, can someone suggest what I should be looking for here? UV, polarized, etc, etc. This is not my area of expertise, so I need some advice here.
