Item is good.But It's not include with screws.I cannot use this item.
Cant focus on infinity because of wrong backfocus distance. Innacurate information from seller. Whole filter drawer with mount is 27mm, not 17,5 as stated. Filter drawer (27mm) + Canon->Nikon adapter (3mm) + Camera backfocus (17,5mm) = 47,5 total. But Nikon lenses work on 46,5 backfocus distance, so its not possible to get focus.
