New guy here with a little help/insight....
I ordered two different lenses from DX on Nov 16 and got them Nov 29. I did choose the expedited shipping if that helps. Two things I noticed, the 92 degree lens (3.6mm) had some softness on certain parts of the picture. The 85 degree field of view (3.6mm) looked really good except it cut a tiny portion of the top and bottom left of the picture(as did the other lens). I have ordered one more lens for $3 from a company in Florida to try out before I make a large order to replace on the cameras I have installed on a couple of houses.
On the order from DX, I was given a tracking number that I used at USPS.com that allowed me to follow its progress. Has anyone else got a tracking number?
