So turning the focus during a slow shutter creates some pretty cool effects.I have to try this on fireworks next time I get the chance. Lens: Canon 17-85mm f/4-5.6
My canon 50mm is now back in the house. I must say canon is providing a great service - yes, granted, the warranty was still active, but they still replaced a focal slider within the camera with no hesitation. Thats great!
