K&F 46mm UV Filter – Classic Slim with Multi Coat

The Two Main Functions of a 46mm UV Filter

A UV filter is seen by many professionals as an essential piece of equipment. It serves two functions. It protects the front element of the lens. It can also enhance the picture quality of your captured images.

A filter, like this 46mm UV filter, screws onto the thread found at the front of your lens. Once attached, it sits unobtrusively in front of your lenses front element. In order for it to be unobtrusive, you will want a filter with a slim profile, like this K&F Classic Slim series filter. This super slim and lightweight aluminium frame effectively avoids dark corners when shooting at wide angles.

When in place it can protect the front element from being touched. This will keep it free from fingerprints and oils. It is also a bit of a shield against dirt, dust or mud getting onto the lens. While using your equipment out in the field the UV filter will protect the lens from accidental scratches and guard the lens front element from chips and scratches.

Apart from the protection a UV filter provides it can also offer optical advantages. As the name suggests it also filters out UV (ultraviolet) light. UV light can result in a bluish colour cast in images. Filtering out UV light can reduce haze in images while improving contrast for a clearer picture.

Because filters attach in front of your lens, you will want to ensure you use high quality products only. These 46mm UV filters are made from glass imported from Japan. To improve their performance these K&F filters are multi coated. The coating is to prevent fogging. It also has a blue coat. This works to provide high transmittance and low reflectivity.

This filter is compatible with all 46mm threaded lenses. Please verify your camera’s lens thread size. This is usually marked somewhere on the lens barrel or printed underneath the lens cap. It is usually a mm reading followed by a “ø” (diameter) symbol.
