新手需唔需要用 Filter?
It has nothing to do with 新手.
Filter is a piece of glass protecting your lens. Special effect filter is difference issue.
All my lense have filters. Other than protect the lense and also take out the UV.
I think $200-$300 filter should be ok unless you don't mind to spend the extra money.
A cheap lens does it need an expensive filter to protect it? you make the call.
