with increasing thread diameter prices rise significantly and so can an overtake but the bastard. But who but what keeps on his equipment should not be stingy. For my Olympus Zuiko 12-60mm (72mm thread) of Hoya UV filter is the perfect complement for the benefit of the lens.
If you want a very high-quality UV filters should definitely resort to this filter. No traces of reflexes, resistant even with wind on the sandy beach, thread fits well and does not become loose.
