Every camera lens should have one.
on 6 May 2010
If you're going to be using a good quality lens or any lens in fact, then a UV filter is the essential piece of equipment.
When fitted it performs two very important functions.
Firstly it filters out UV rays, exactly what it says on the tin, this makes your photos look better to some small extent.
It also protects the lens from scratches and knocks, making it easier to replace and less costly.
I use Sigma EX DG range of lenses, so that is why I use their filters.
Stick to the well known manufactures, to get the best results.
As well as the filter, the lens hood should also be attached at all times, as this gives added protection.
One last thing, before you purchase any filter check the size, it is shown in m.m. on the front of the lens.
