I can't speak highly enough about Donny's products! IMO, they're simply The Best!
And, Donny is a killer guy, so I also like to support him and his products as much as I can.
[This is definitely the right thread to re-post this]
As a photographer, I need to be as absolutely quiet as possible when doing animal / nature shots..
There's nothing worse than loud shutter clicks and auto-focus motors scaring away the furry woodland creatures..
What better way to quiet down my equipment even more than to use one of DonnyFL's DSLR Lens to 1/2"-20 UNF adapter..
That lets me install my suppressors right on the end of my lenses, and boy does that ever quiet things down..
The 25 cal bore size also limits enough ambient light to allow for really cool pin-hole-cam special effects..
