I bought 3 of these camera lens for my 3 Dquad obsessions and I'm loving them. The fov is perfect. The only problem I have though is I have them on foxeer arrow v3 cameras. I had to leave off the tightening ring so I could focus the lens. I just put a drop of Super glue on the thread so the lens can't move. As always great service and quick delivery from Nemo's.
The quality of this lens is spot on and the extra field of view was exactly what I was after (wider than the standard).
