ND-------Extend exposure time. Try an ND, or neutral density, filter. ND filters reduce the amount of light entering the lens. This makes it easier to achieve effects such as a shallower depth of field or blurred motion.
K&F utilize cutting edge technology you're going to say goodbye to this common issue with wide angle lenses and variable ND filters.
In addition to state-of-the-art MRC, our optical engineers developed new nano coating layer technology, called nanotec, from the ground up to repel dirt, water and other elements by beading rather than absorbing and smearing. Set in our workhorse and built to withstand extreme wind, salt water, dust and other abrasive conditions and elements.
The ND filters are made with premium Japan Optics glass, which could resist scratch,protecting your camera lens well.
The darker version of this is utterly indispensible for LOG video with high ISOs forced by the camera, combined with fast lenses you'd like to open up for depth control/"bokeh". And only the wildly expensive PolarPro has a similar option. And while I suppose the PolarPro might be somehow better - I'm simply not rich enough to find out! In the meantime the K&F has served very well. I use this primarily on a Fuji X-T3 with f1.2 and f1.4 prime lenses, shooting F-LOG at the required minimum 640 ISO. Secondarily on a Fuji X-H1 (800 ISO LOG!) and even a Nikon D750 for occasional stills.
Overall I am happy with this filter. I did a lot of research when looking for ND filters for my Fuji XT3. I had three goals when choosing an ND filter.
The first thing that stands out is the nice packaging that it comes in. Definitely meant to keep the ND filter safe. I tried a few video clips and some photos with the filter attached to my Zeiss 24-70mm lens. The image quality was very good and the filter feels really substantial.
I bought this for mostly waterfall photography because my big name brand 5-10 stop ND was overkill for my needs. My exposures were 30 seconds to one minute, so I didn't push this filter to the extreme, but I see no artifacts or color cast (beyond the expected shift from long exposure to begin with). You are not wasting your money. Great investment!
So if you don't go beyond about half way as far as filtering, the filter does ok. Otherwise it introduces a sepia-like color cast to the image. And even though it's designed to work with the ultra-wide iPhone lens, it really doesn't at the higher stops as you do get vignetting.
You can spend a TON more on a "nicer" fader, or a set of multiple ND filters, but the quality from this is great, and since it's variable, you don't have to carry a bunch of filters around, just 1. This filter gets you 95% of the quality of higher end filters at 20% of the cost.
A bit pricey but not at all. Its bitter sweet when it comes to filters. Really good range to enter the ND world. This works great!
Excelente producto tal como lo dice no produce la cruz que en filtros mas baratos si aparece, los materiales se sienten de buena calidad, como inconveniente no lo pude poner en un sigma 17-50mm f 2.8 y poner el parasol incluido a la vez, ya q el borde del filtro es mas grueso y no pueden estar juntos
