I wanted a "cinema mist effect" for my a6700 – mainly for videography. For video, an ND filter is essential...

So, for the best solution, I looked for a system that could be stacked. Initially, I was a bit skeptical whether magnets would work well – but lo and behold, it's rock solid (perhaps too solid? Time will tell). The ND filter adjusts very smoothly and doesn't slip. Perfect! With the mist filter, beautiful lighting effects and the cinematic look I wanted come through perfectly.

I've included a short video where, based on the sound, I think you can clearly hear how smoothly the magnet engages (please ignore my dog's pawing in the background).

I've also included some sample photos taken with the a6700 and Tamron 17-70 f2.8.


A quick explanation of the image order:

1. Image completely without a filter

2. Image with only a Mist filter

3. Image close-up without a filter

4. Image close-up with only a Mist filter

5. Image with an ND filter
6. Image with an ND filter + Mist filter

7. Image with an ND filter as a close-up

8. Image with an ND filter + Mist filter as a close-up

Conclusion:

The quality of K&F filters is, as always, fantastic. They are CNC-machined parts, aren't they?!

It's always the same aesthetic effect, like with those smartphones with the Apple logo. Oddly enough, people always find these orange K&F filters stylish and comment on them – just a little anecdote.

Definitely a perfect system that will replace my simple ND filter!
