hi,
today i bought D90 kit lens and a UV filter. The salesman sold me this filter Vitacon at 20S$. Is it as good as hoya? I just afraid that he would cheat me.
Then you shouldn't have bought first. There's always another time where you can pop in to buy after you've done your homework. If you really need a cheap and good filter, go at least for a Hoya Pro1 Digital MC Protector, nothing less.
For myself, I'll get Nikon NC whenever I can. Many places don't carry stock for NC which can be quite frustrating.
