How to Install a Filter on a Canon 600mm Lens
- 1). Purchase the correct-sized filter. For example, the Canon EF 600mm f/4L IS USM Super Telephoto Lens requires a filter with a 58mm diameter.
- 2). Remove any current filter on the lens by unscrewing it counterclockwise.
- 3). Set the filter threads into the space on the front of the lens and gently screw the filter clockwise. Hand-tighten the filter only.
