Added on October 20, 2009, 3:59 amabout filter, why do we need uv filter? some site was saying that it protects the lens. do we need to buy a filter for each and every lens that we have?
basically when you fire a lot, the batteries get overheat. when the batteries overheat, its best to cool it down. depends on the quality, some batteries can even explode if it overheats. when your set of batteries overheat, its best if you take it off until it cools down.
can't help with ur nissin problem
uv filters are use for protecting your lens. also used to prevent uv rays from entering your sensor, hence disrupting your picture. depends on you. if you think your lens is not worthy of having a filter, then maybe a cheap filter would do. if you have an expensive lens, say a good prime, you're better off with a uv filter, the cheap or pro one.
please correct me if i'm wrong
