I have several 808#16s and they all work great. 808 #32 with a D lens is completely out of focus. I was able to carefully rotate the lens and record video with each rotation, and finally managed to make it usable. I would like an easier way to refocus the lens. I contacted a manufacturer in China and was unable to sell me a new focal lens as it was out of stock. I hope that one day I'll be able to focus it properly.
