The Rollei Bay 6 Skylight Filter (R1.5) is a wise initial investment. Due to its light pink color, this filter reduces the bluish cast of daylight and produces a pleasing, warmer picture tone. It can help protect your lens from dust, moisture and scratches, which can lead to costly repairs.
A Skylight filter adds a bit of warmth to an image that is shot on a cloudy day. Or if you're shooting in open shade, a Skylight can bring back some color to your skin tones.
In addition, the value of a filter covering a lens has been well-documented over the years. How many stories have we all heard about photographers dropping lenses and smashing front elements? With a front lens protection filter on, the chances of preserving the valuable glass in your lens increases many fold. Shall we call it a form of inexpensive insurance?
