Absolutely wonderful set of ND filters for my camera. These are an absolute must for not only being able to filter and control how much light is coming to the image sensor, but also to protect the lens. I find myself trying out a bunch of these actually, and this particular brand feels very premium. The edges of the metal ring are clean but not sharp, and the glass is crystal clear. Very affordable too! Great value for how many different ND filters they give you. Highly recommended!

Set brings a noticeable improvement to footage, giving smoother motion and better control in bright conditions. Filters clip on securely and stay put even with plenty of movement, yet come off easily when swapping between strengths. Optical quality looks clean with no odd colour shifts, and reflections are well kept in check. Case keeps everything tidy in a kit bag, so it’s simple to take them out on walks or trips.

Really nice quality set of ND filters that fits my action camera perfectly. The optics appear clear with no discernible distortion.. Overall a great product that works very well.Recommended.

The filter set comes in a very practical, but slightly large case. The attachment to the camera works perfectly and the filter thread is well cut. I couldn't find any flaws, blur, or color stitches.

These are high quality filters specifically for the DJI Osmo Nano. I'm not sure if they will fit other models or brands though. A CPL is considered essential when around water or skies so you can get some decent contrast and the ND variants will be useful especially if you are filming in bright lighting conditions.Everything can be stored in the case and the quality is very high, something that K&F Concept are known for. Very useful if you have the Osmo Nano.Highly Recommended and a reasonable price considering you are getting 4 filters.

Good robust filters that fit perfectly onto the camera.Not heavy so doesn't affect calibration.A good variety of strengths for stills or video that really do help smooth out the footage on a bright day.

Thank you for taking the trouble to read through my review

For all those who don't feel like reading through everything, I'll write a pros and cons at the end.

Today I would like to write my personal opinion about the K&F Concept filters for the DJI Osmo Nano, which I was able to test as part of the Vine program. This doesn't affect my review in any way. I hope I can help you decide for or against the product.

The filter set for the DJI Osmo Nano comes in a small plastic storage box with a cleaning cloth.

It contains filters in the following thicknesses
- ND 8
- ND 16 - ND 32
- ND 64
- ND 256

- as well as a CPL/polarization filter.

The filters are a perfect fit for the DJI Osmo Nano and can be easily replaced by the actual lens protector. Simply unscrew the existing Osmo Nano lens protector and screw in the desired filter. When taking pictures with the filters, I could not notice any annoying color deviation. The CPL filter removes reflections reliably. The camera should have a fixed position for video recordings, as the filter would have to be adjusted when the camera moves.

Personally, I could have done without the ND 256 filter in the set. This is certainly only needed in absolutely exceptional cases. On an ActionCam, this is unnecessary (at least for me). Here I would have liked an ND2 or ND4 better, although the ND2 would have been close to the CPL filter in terms of dimming.

Pro:
+ storage box
+ No annoying color shift
+ Filters are sealed
+ Price for the

Neutral set:
- ND 256 filter barely necessary

Thanks for taking the trouble to read my review. I hope I was able to help with the decision making process.

This filter set for the DJI Nano leaves nothing to be desired.
Improve your video quality by simply applying these filters so that you can enjoy the perfect video footage without lens flares even in strong sunlight.
