Im still learning and I have a few questions with filters. I not ready to start playing with different types yet but I need some protection on the front of my lenes. I'm thinking an entry level standard UV filter will do the trick. I need 49mm, 52mm and a 55mm
1. Should I have a UV filter on at all times to protect?
2. What brand do I buy? They seem to range in price on Ebay from $5 (China special) to $22 (Hoya HMC UV) and then go up in price for the pro models which don't interst me
