No es caro para la calidad que da, viene muy bien presentado.

Mo mujer se creía que le iba a pedir matrimonio, tiene una caja muy bonita.

最近リュックもカメラ周辺機器もK&Fを選ぶことが多くなってきました。
レンズフィルターは幾つか使ってきていますが、どれも申し分ありません。コーティングも綺麗ですし埃も取れやすいです。

Extremely well-made. Very low profile with excellent machine work on the body and threads. And the glass and coatings are top notch. I’ve switched over from Hoya HD3 to these on all my new L lenses.

water resistant coating save my day

Ottimo filtro, ve lo consiglio.

I've heard varying opinions on the benefits of keeping a UV filter on the end of a camera lens. Many people say it's smart because if you drop the camera, replacing a filter is much cheaper than repairing an expensive lens. I've heard others (particularly professionals) say it doesn't make sense to buy an expensive lens and then put a cheap piece of glass in front of it that will just degrade the image. Those folks say keeping the hood on the lens will provide plenty of protection and if you have an expensive lens, it should be insured against damage anyway.

I've invested in some good Canon L-series lenses so I'm torn on the best approach. I've been leaning towards going without the UV filter, but I still want one if I'm somewhere like the beach and sand or dirt is blowing. So if I'm going to put another piece of glass on the lens, I want to make sure it's high quality and this filter meets that requirement. You can tell when a vendor has put a lot of thought and care into a product and it shows throughout the process. This filter comes in very nice packaging and they provide a high quality case that has a magnetic latch and a nifty ribbon on the side that you pull to extract the filter from the case. This keeps you from having to reach in and possibly get fingerprints on the filter. Great design!

As to the quality of the filter itself, I don't see any aberrations in the image when I use it. This line of filters from K&F aren't cheap so they won't be for everyone, but if you are taking your photography seriously, you should consider this product.

This is a great filter and fits my sigma e-mount lens perfectly! The packing is fantastic and the case to carry the filter is designed so nicely! Love everything about it!

This new line of pro grade filters from K&F Concept is truly fantastic.

These filters are super slim, with smooth threads that attach easily to my lens.

The UV filter doesn't have any color cast or produce any optical aberrations in general.

Just a crystal clear filter to keep your lens safe.

Comes with a padded case for safe storage.

K&F concepts. They’ve been around for awhile now, so I trust them and their camera gear.
As far as their UV filter, it’s awesome.
The packaging itself is beautiful. The box it comes with actually turns into a frame for a photo that you can place into the center of it.
The filter case is also beautifully made. Really premium feel. The package also includes a cleaning cloth.
But the filter. First off, putting it onto my lens was pleasant. The partially texture/knurled surface of the ring makes it putting it on and off easy. You can really get a grip onto the filter.
The clarity is way better than my previous cheap Hoya. This might be due to the different coatings this filter has but it’s been noticeable.
I mainly use UV filters for protecting my lenses. I’ve had a few drops and I’m always happy that I’ve had a UV filter on.
You don’t want to cheap out on a UV filter because it may affect image quality and I’m glad I’ve got this one from K&F. I’ll be leaving this on this lens forever!

I have had many UV filters from multiple brands. This is now one of my favorites. It is exceptionally clear, light weight, and well built. The included storage case is also top notch. I'm going to have the leather flap labeled with a laser. The box converts into a picture frame which is oddly cool.
