Don t rush out to buy a skylight filter

Putting a clear filter on the front of your lens to protect its surface sounds like a great idea. After all, your lens was an expensive investment. The end of your lens is stronger than you might think, however, and easy to clean if you don t let the dirt build up. Dispensing with a skylight filter will not only save you money, but also avoid the chance of introducing light problems due to increased reflections or the slight reduction in the level of illumination reaching the sensor.
