I'm so excited, I've been looking for a 35mm lens. I looked at the Sigma and Canon but after reading many, many reviews, decided to try to find a good used Canon 35mm L lens. Well, lucky me, someone was selling all their equipment and had a almost new Canon 35mm f1.4L lens for sale. I contacted him and bought it for $900 (candian). Now I need to get a good filter for it. What would you suggest without braking the bank. there was a lens hood included but I'm so paranoid, I just feel better if it had a protective filter. Any suggestions would be appreciated.
