FILTERS are important for your camera....
A UV filter will provide protection for your lens or camera, allowing a
scratch or crack to be no more than a $15 or so replacement, as opposed
to replacing an entire lens or camera. It's like insurance for
your camera.
Before purchasing filters, you must know the
filter size required for your lens or camera, usually found on the
lens cap or end of the lens itself. Many times, different lenses
require different sized filters.
