Guys, as bro Octarine has pointed out, the facts are:
1. UV does not affect digital cameras, so a UV filter is useless. UV filter do not reduce glare or flare. UV filters were necessary in the old film days as UV can affect film. Getting a clear or protective filter is wiser for the digital age.
2. Multicoating do not make cleaning easier but makes it harder. In fact many filters are hard to clean because there is multicoating. A glass filter with no coating at all will be the easierst to clean. The actual purpose of multi-coating is to reduce flare and glare. The new generation of filters now spot an additional layer of coating that makes cleaning easier (i.e. B+W MRC, Hoya HD, Kenko Zeta).
3. Brands like Hoya Kenko Marumi have cheap and not-so-good filters too. So do your research and get a reasonably good one. IMO, I feel that getting top grade filters like B+W MRC, Hoya HD or Kenko Zeta for kit lenses feels like a waste of money. I personally go for Kenko Pro 1 Digital line of products for most of my lenses.
