You sprung for a fancy camera but your images are still lacking a certain punch. Enter Circular Polarizer lens filters from Manfrotto. Not only will these filters protect the front element of your lens from dust, moisture, and impact damage, they’ll also help dramatically improve image quality. Without a filter, UV light can enter your lens, reducing contrast and the sharpness of your images. These filters reduce reflections and boost color saturation and contrast. They have up to 90% light transmission, allowing more light for faster shutter speeds or more depth of field. The filters come in three quality levels and are only available online. $50-170; manfrotto.com.
