Handy for older manual film camera with max 1000 or 500/ sec shutter speed to meter in sunny daylight, lens wide open. Metering can be adjusted by turning the ND to meet the correct light exposure at a set shutter-speed and choice DOF (f-stop) combination. Wonderful tool for needle metered or LED array camera where you see the progress of exposure as you turn.

Retractable Rubber hood is the best solution to attach a hood.
Lens cap for a 67mm will be 72mm. I will assume 1 size larger.

The DJI Mavic 3 Classic already takes very good pictures ex works, but using ND/PL filters makes the pictures richer in contrast and reduces reflections. That's why I decided on the set from K&F Concept. The filter was delivered in a storage box.

Assembly is easy, turn the frame slightly to the left, remove and simply place the new filter on it offset to the left, then turn slightly to the right and this will fix it. So a quick change is possible. I generally use the ND/PL filters for photos and videos. Because the colors come across more effectively and better. When it comes to ND/PL filters, I mostly use the ND8PL and ND16PL. ND32PL and DN64PL when it is extremely bright, in winter when it snows, on days with clear skies and clear sunshine. From ND32PL upwards, the filter softens the rapid movements of waterfalls and clouds, which comes across as silky. Everything else is razor sharp. It's best to try it yourself and then compare the results.

The quality of the materials, including the glass, is impeccable and the processing of the filters is good. The attachment is easy and quick, they hold reliably, fit perfectly and the recordings are much more professional.

The PL filter minimizes mirroring and reflections. In addition, the images become more colorful and richer in contrast.
Explanation of the ND filter: I use them for long-term exposure and depending on the sunlight. This allows you to take softer shots.
What is a neutral density filter/ND filter? A neutral density filter is a filter where the glass is completely darkened so that less light can enter the lens.
So it is possible to choose longer shutter speeds and to achieve the corresponding effects, such as foggy water or soft, long-drawn-out clouds. This would not be possible without a filter, as the image would be extremely overexposed or even completely white.

About the neutral density filters:
There are different variations of gray filters with confusing, different names from different manufacturers. I don't want to go into the different manufacturers here, just the different designations. I had to read through it first, but basically, it's easy to understand.

The designations for this set mean:
ND8 = Slowing down the shutter speed by 3 f-stops to increase the exposure time
ND16 = slow down the shutter speed by 4 f-stops to increase the exposure time
ND32 = slow down the shutter speed by 5 f-stops to increase the exposure time
ND64 = slow down the shutter speed by 6 f-stops to increase the exposure time

This allows outdoor scenes to be created very effectively and effectively. With the use of the various filters you will see how beneficial they actually are. Every professional works with such filters ;-)

Thank you for taking the time to read my review. I hope that I was able to help a little with this.

What can I say? This is a great tool. It gives so much flexibility for ISO speed and shutter speed. It has low distortion and internal reflection. This is a MUST on the front of any lens and the quality is amazing for the price!!!!

I use this filter for video to get the right shutter speed regardless of the aperture. A variable filter is of course perfect for this. I can't see any loss of sharpness or similar, but as expected there is a slight, hardly noticeable color cast, which you can easily correct - if you want - on the camera.

I use this filter for video to keep the correct shutter speed regardless of the aperture.

Good quality filters. It gives me the ability to have a slower shutter speed and create stunning images.

I got this because I wanted to have 1/50 shutter speed and a wide aperture in an outdoor shooting environment - I am video recording. It works well. One thing you should know, you cannot put your kit lens lid on this filter, otherwise you need to remove it.
