JETA,
As I drove home I thought of something. You need a good UV (0) filter to protect that new lens. You can get a Hoya UV (0) for around $40, and it is worth every penny for two reasons:
1: it protects the glass on your lens
2: the (0) dose not affect color yet still blocks UV kight you don't want.
Any other filter than the UV (0) WILL affect color.
