K&F Concept Super Hard Nano-L UV Filter Multi Coated Review

You may have used a UV filter before, you may have not. If you come from the film world you will definitely be familiar with their use.

These pieces of glass reduce the amount of ultraviolet light entering the camera which would in the film world, result in better colours. Modern digital cameras just aren’t as susceptible to issues with UV light. So why would you use one?

Well, they can have a second important purpose. Protection.

You’ve invested your hard-earned cash in a nice lens, and you’d be pretty saddened if you were hiking out to that perfect landscape photography location and you manage to drop or scrape the lens, or maybe you’re just shooting at the coast and it’s windy and sand is blowing across the lens. Surely it’s better if a filter, at a fraction of the lens cost, takes the brunt of the pain?

Sounds like a no-brainer.

But wait, there are considerations. If you’re going to put an extra piece of glass in front of your sensor you need to be sure it’s going to have no detrimental effect on the final image captured. Loss of clarity, colour casts, etc.

To this end, I’ve been trying out the K&F Concept Super Hard Nano-L UV Multi Coated Filter over the last few days.

I’m using the 77mm thread to fit on my Sigma 10-20mm lens. The filter comes in a stylish box and circular plastic storage case with a twist lock. The plastic case contains a quite clever rubber mount which stops the filter rattling about in transit.

The filter is very thin but I had no issues using the outer thread to attach my 100mm filter holder. My standard lens cap also fit without issue. There is the consideration that such a filter may not work on every lens, especially a wider fish-eye lens which will have a curved front element.

The most important factor with this test was to make sure that the use of the UV filter would not impact on the quality of the final image. I took a trip out into Leeds as I’d noticed that the John Lewis building was sporting a fantastic rainbow in support of Leeds Pride. The variety of colours would provide an ample test subject.

This is my control shot with no filters attached.

This is the follow up shot with the K&F UV Filter attached taken a matter of seconds later.

They were both edited in identical fashion in Lightroom. A 1/1 comparison between the control image and the K&F UV Filter image showed no artifacts or degradation in quality, if anything the colours with the UV Filter have slightly more depth.

So there, we can see that if you are looking to add a UV Filter to your kitbag, there is at least one on the market that is very high quality, and won’t affect the final image.
