i just got my 10-22 and i want to protect it and get a filter that will have some type of use...other than just protection...
what is a good CPL filter?
i was reading about the CPL filter that canon make and every review said it doesn't allow you to use the canon lens cap...
and that filter was $124.xx.
the last thing i want to spend $$$ is a filter that needs an aftermarket cap.
for starters, i just want a filter to protect the glass, i am assuming they make a plain 'clear' filter.
CPL would be nice to bring out colors.
thanks.
