Today I demonstrate how to put a B+W UV / IR cut filter (77mm) onto my Canon 24-105 F4 L IS USM lens. Although I used my lens, the same procedure is for all diameter front-on lenses. Screw them in.

I personally recommend either B+W or Heliopan as their quality controls are the strictest of the filter manufacturers
