occasionally carried a few individual filters with me. But it was often too expensive for me to fiddle around with it in nature. Screwing the filters together to get further addition levels is also fiddly. There are enough individual ND filters, but every time you had to change the filter again... With this filter here you basically trick the entire handling process. I hadn't even found out such a thing existed. So I included a little video so you can see the function. Even if there is "only" ND2-32 here, you can still see what these products can do. Especially for experimentation, a matter of seconds, sometimes with a different filter setting. With low filter strengths, the camera automatic is sufficient and you can see the current shutter speed when setting the filter. Soft water structures with relatively bright light or soft clouds in the sky etc. pp. I didn't really notice scattered lights or reflections, but I edit something like that on the PC anyway. The price of this product is high, but considering that it covers multiple filters at once, it's not too bad. However, the general question is what kind of filters do you really need. I previously had an ND8 and an ND1000. Sometimes an ND 4000 would have been required (to safely create 'abandoned' objects/rooms). However, I find the concept here really innovative and practical.
