I finally got a chance to try out this filter... pandemic lockdown makes traveling a problem. I found that the filter is a little bit difficult to remove once in place, so you may want to make sure you don't tighten it down completely. I had no difficulties with colour reproduction while using this filter, it worked very well. Excellent for extending exposure time for those very smooth water effects. I'm posting images without and with the filter for comparison.

You can spend a LOT of money on ND filters. I'm no pro, my photos make me happy but don't make me money, so I didn't want to spend $100+ if I didn't have to. But I'd heard a lot of stories about cheap filters having bad colour cast, or not affecting exposure accurately. So I figured I'd take a couple test shots with this one. And I'm very impressed.The first photo was taken with my 5Div and 85mm f1.8 lens at 1/20s, f1.8, ISO 100. Untouched jpg SOC.The second is the same camera and lens, now with the 10-stop ND filter, in about the same position (I picked it up to change settings and put on the ND filter): 3.2s, f1.8, ISO 1600.To my amateur eye, there's no significant change in color or exposure... K&F says 10 stops and it really is.For what these filters cost this is really really good.

Fits perfectly on Canon RF 24-105 f/4L. No issues with fitment or quality.The weather and quarantine hasn't really been great for shooting. So I haven't been able to get some clouds or streams as I wanted. So far with a few test shots it's as you would expect from a 10 stop ND filter. If I can get out to take some tripod pics I'll update this review.It comes with a really nice case. Nicer than the Amazon basics ones. However my Amazon basics circular polarizer is too fat to fit into this case. Too bad because it would have been nice to just carry this nice case around.

K&F Concept 77MM Neutral Density Lens Filter 10 Stops ND1000 Filter is impressive at this price range. I have used expensive filters that leaves noticeable color cast. But L&F filter leaves minimal color cast that is easily correctable in post-processing.On the downside, built quality is not as good as expensive filters such as B+W. Also I have noticed that it scratches easily. So as long as you are careful, it works well.I can recommend it to anyone looking for good results at reasonable price point.

Love the product. Good for long exposure day shots. Have not noticed a loss in image quality on my side.

I was always hesitant to use these and usually just relied on ramming my shutter speed through the roof. I'm pleased to say that I'm very happy with this item and its results. The clarity appears to be the same as without it. There's a slight color cast to the image but with digital this doesn't matter.

On a very bright day, and when you need to control the light for a long exposure this ND filter comes in handy. Just make sure you use a stand, not recommended for hand holding due to hand shake. Over all it is quite good and worked well for me.

The first thing I checked was the colour cast that this filter might impart and any effect on resolution. The lens used was a Sony 24-70mm f/2.8 GM, a very sharp lens at 24mm. I found practically no colour cast and no resolution loss, keeping in mind that the sensor itself undergoes some reciprocity failure during long exposures (it's worse with film).

slim line does not vignette on my 24mm zoom no artifact and allowed an 8 second exposure at ISO 100 f 8 on a clear sunny day. in addition the super fast delivery made it possible to start using it right away
