First of all, I am really new to EVIL photography. Snap pictures with a P&S like a fool, but this is all new to me. So far, I picked up the OM-D 12-50 Kit and just got a lightly used 45mm for 300 bucks (did I do okay?) So my question is, do I need to pick up filters to protect my lenses, or are filters for another purpose? How much does brand/quality matter? Also, I like the look of the lens hoods, but what are they for exactly? Yeah...huge n00b. Thanks for taking the time to reply. And I promise to share pictures soon.
