Is it possible to use a polarizer and a ND filter at the same time?

Question

Is is possible to use two filters (one polarizing and one ND) at the same time on a 18-55 kit lens from Canon. I am new to photography and wanted to work with filters. Do you suggest me buy these filters?

Answer

The front element of the 18-55 rotates when focusing, which makes using polarizing filters a bit irksome. But other than that, yes, it should work, although using multiple filters on a lens is something that should be avoided as far as possible on general principles because of the added risk of flare, internal reflections, vignetting and other optical nasties.
