I still haven't received my HD keychain camera, so maybe someone can help a little in the meantime.
I just measured the lens on one of the non HD cameras and it has an M5.5 x 0.35P thread (as far as I can measure at least). Could someone see if it's the same lens thread size?
I'm asking because I've found a supplier for wide angle lenses... well, in theory at least, I have no idea if they sell in small quantities yet; but it's worth taking a look.
Apparently the name of the manufacturer is Misumi, here's the page with the lenses
. The 2.1mm focal length lenses have a FoV of 158 degrees, about the same as a GoPro Hero camera I think; I'm not sure of the FoV for the 3.1mm focal length ones, but I suppose those should be better?
OK, I see that the Inquiry button open a request form and apparently the minimum order is 100 pieces; if I could confirm the thread size of the lens then I could ask for a quotation and see how much is it per piece.
