Very nice standard filter set containing a UV filter (clear) and a CPL filter.

These are fairly slim filters which are less likely to result in problems like vignetting around the edges. Very well made, with machined aluminum construction on both of the filters.

The CPL filter is a little darker than what I'm used to, making it better suited for outdoor, daylight shooting as opposed to indoor conditions.

The UV filter is the best I've used, crystal clear, without any blueing or other artifacts - perfectly, 100% clear. I keep the UV lens on my camera's lens at all times for the protection since its so clear. Works well with stacking additional filters.

Threads all work nicely, and the CPL provides fluid rotational adjustment.

Great deal for this set of starter filters.

I am familiar with KF Concept from both their filters and their lens adapters. Tjey have a host of other photographic products. Because I am familiar with those, I was comfortable ordering this product. When I ordered it, I thought it was *just* the circular polarizer. I was surprised and pleased to discover it was a combination. For me, 62mm makes the polarizer useful on several lenses. The multicoated UV filter was a bonus. The combo comes securely protected. In use, the polarizer reduces glare from surfaces and deepens the blue in skies. This is what one expects, yes? The beauty is that the multicoating essentially eliminates any glare from the filters themselves. That coating also makes them easy to clean and keep clean. They are made with optical glass, so I'm confident in their durability. The knurls on the filter rings make them slightly bigger than the lens barrel they're installed on. I have had issues with this on some vintage lenses, but not on the modern AF lenses I got these for. Overall, I recommend this combination both for function and for excellent value.

I got this to use on my Panasonic 45-150 lens, which is the lens I use the most outdoors.

I misunderstood when I ordered this that the UV lens is also half the polarizer, but it works well. The UV filter fits the lens easily and smoothly, the polarizer attachment filter fits well, and works well at an angle from reflective surfaces.

The pics I shot using these with my Panasonic GX85 came out well with no optical aberrations. There are better quality filters out there, but they cost a lot more - this set is the perfect combination of price, quality and optical quality. I'm very happy with it.

This is actually two filters, a UV and a circular polarizing one. You can use them separately or stacked one on top of the other. These are well made filters, the ring is very small so they won't cause any vignetting even when stacking both filters on fairly wide angle lenses. These threaded onto my lens smoothly and stayed on securely. They only reduce the a little, and once they are screwed on there is an outer ring that lets you rotate the polarizer to get the best effect.

The UV filter helps reduce atmospheric haze and makes the air look clearer. A lot of people also leave a UV filter on to protect the front element of their lens from dust and splashes. The Circular Polarizer will help reduce reflections from things like water, glasses and windows. Because it reduces reflections, you can see down into water making it look clearer and cleaner. It also helps deliver a clearer sky image when taking photos outside.

This is the "K" series filter, they also have a "D" series. I'm not sure the exact difference between the two as K&F's own website doesn't really explain it. As near as I can tell the "K" series ones (this one) are slightly cheaper with less layers layers of coating, the K series doesn't seem to have a water/oil repellant coating.

In any case, well made filters that do the job.

Pair of filters that exactly match the descrition

I have read bad reviews on people getting the filter stuck or it unscrewing during use. If you turn it gently in the correct direction using the ring, you won't have any problems I'd say. For me these work really well on the Sigma lens

Does its job

K&F always makes great products at a good price point. I would definitely recommend them to a friend

I wanted to play and try... I know the principle of a polarization filter, but I didn't have one yet. Since I have a new camera and lenses, this was the opportunity now.. from various tests, this was found to be acceptable. It works great and an impairment of the image quality was not noticeable to me. Price performance is great. Would I buy again

Over the years I've tried a number of manufacturers for filters for my camera lenses and when I tried the K&F glass filters I haven't look anywhere else. The K&F Glass filters outperform about 80% of other manufacturers. I'm a long-time nature photographer with scenery and wild animals in their natural habitat. When I'm out in the rainforest focusing on a cougar I want the first shot to be the best as I may not get a second one.
