Will the circular polarizer I bought for my Canon EOS Rebel K2 work on the Canon XSi I'm getting soon?

Question

I guess what I'm really asking is will a normal circular polarizer work on a Digital SLR?

I'm not too familiar with cameras and accessories. :d

Answer 1

As long as it's the same size across the front of the lens, it will work fine.

Answer 2

The circular polarizing filter is necessary for ALL auto-focus cameras, so yes, it will work on both your current and new camera.

Answer 3

Yes it will.
