The title of this review pretty much says it all about the K&F Concept 52mm MCUV Lens Protection Filter; in fact even the product's name calls out its most important function. This type of filter is mainly used to protect our expensive camera lenses and K&F is upfront in naming their product as a "Lens Protection Filter."

As such this product seems to be made well and, in use, has not introduced any aberrations, glare or ghosts to pictures taken with the filter either directly on the lens or in addition to other filters. It is very thin and has both inner and outer 52mm threading. In comparison, the K&F UV filter is much thinner than the same type of filters sold by other manufacturers without any discernible difference in photo results. My only complaint is that attaching the K&F filter, like many other K&F filters that I've tried, can be a bit tricky and produces a more distinct "scratchy" sound than other filters as it is being screwed onto its mount. However, I've not been able to see any negative results that could be attributed to that sound or its creation.

All in all, I think the K&F Concept 52mm MCUV Lens Protection Filter is a product that should definitely be on your possible purchase list if you are shopping for a UV protection filter. Its competitive price and thin form factor, together with a lack of any evident drawbacks, are definite plusses and I therefore rate this lens a solid 5 star product.
