Why you can trust Digital Camera World Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out how we test.

Whether you are a professional photographer or an enthusiast, you know that camera lenses can be quite expensive, and the cost of replacing or repairing them can be exorbitant. This is why it's essential to take measures to protect your investment, and one of the best ways to do this is by using a UV (ultraviolet) or even better MCUV filter (multi-coated ultraviolet). 

UV filters are among the most basic filters in photography and offer a range of advantages. The best protection filters for lenses are designed to protect your primes and zooms from accidental damage caused by drops, scratches, or cracks. They can also safeguard against environmental factors such as water, sand, or dust, which can negatively impact the longevity of your lens. This is particularly important when shooting near water or in the rain, as water can cause major damage to your lens. Even condensation can be harmful if you move from a cold environment to a warm one while shooting. 

Tiffen's UV Protector filter

Are you a beginner in photography or searching for a budget-friendly solution? Tiffen's UV Protector filter is an alternative to the K&F Concept MCUV filter. It effectively reduces the impact of UV light and provides reliable protection for your lens - but without a heavy price tag. The difference here is that this filter does not provide a multi-coated surface so lens flare can occur, which can be prevented by using a lens hood when shooting directly towards the sun. 


Are you interested in exploring other camera filter options? We recommend checking out the Tiffen Digital HT Ultra Clear filter. This filter is comparable to the MCUV filter by K&F Concept and performed very well in our testing. Like the MCUV filter, it also has a multi-coated surface that transmits almost 99% of light. The filter has a durable titanium finish and provides excellent protection for your camera lens.
