Camera lens filters still have many uses in photography and should remain a part of any photographer's camera bag . With a variety of camera lens filters out there, you can choose to have one for the reduction of glare or one to simply provide extra protection to the front of the lens. We are here to familiarize you with the different options that are available as well as what they can do for the effects of your photos.
Screw-On Filter: This is the easiest way to attach a filter and therefore is one of the most popular formats. Here, you simply screw the ring-shaped filter onto the lens . These come in a variety of sizes to match the diameter of varying lenses.
Drop-In Filter: If you have a long telephoto lens with a wide diameter, it may include a convenient drop-in system. A small compartment near the rear of the lens houses a drop-in filter.
Modular Filter Systems: Made for photographers with a lot of lenses in varying sizes, having a system allows you to mount a filter holder to the front of your lens and then adjust it accordingly.
Filter Ring Adapters: This allows you to fit a non-compatible filter to a specific size lens. These adapters are also called stepping rings because a step-up ring allows you to use a larger ring than your lens size and vice versa for the step-down ring . Note that size designations are always lens first, then filter.
