K&F Concept ND filter set 58mm ND8+ND64+ND1000 filter, approx.

As an amateur photographer and especially for astrophotography, I of course have a sturdy tripod so that I can take long-term pictures at night, for example with the mount.
So far, I've lacked strong ND filters for the day.

For relatively little money, K&F offers a slim set of 3 in this segment. The three ND8, 64 and 1000 filters are delivered in a foldable bag. The filters can also be easily screwed onto an existing Skylight, the thread dimensions have been kept clean. The package contains 3 wet cleaning wipes.

I did the test with manual adjustments on my Fujifilm X-E2. Set to F22 and set to 1 second in bulb mode using the Rollei remote trigger. As you can see, the first image without an ND filter is completely outshone. ND8 shows at least an outshining sky, at ND1000 it was the end or, as expected, deep night.
It was only the F10 setting and 30 seconds that an image could be seen again.

Of course, I could now also have shot the sea - if one had been nearby - or a stream in long exposure, but with today's sunny weather, wind turbines are a change of pace, aren't they?
:-)

In oblique light, I could not see any optical errors or inclusions on the filters.

Conclusion: I give 5 stars for the money including the filter bag
