I am very pleased with the 1000x Nd filter, One day earlier than expected the good part was in the mailbox and was immediately screwed on the Canon EOS 700D with 18-55mm kit lens. Here I noticed that there is a small resistance when screw and you have to screw bit stronger. But I see this not as "annoying" and therefore it stays with 5 stars.
One can make good long-term exposures in daylight conditions, but for amateur filmmakers with the DSLR it's too dark. Here I do not recommend for such a use. I turn next to movies, taking photos have detected a for me, it is a real gem.
