For inspection purposes I am looking for a zoom lens to replace the stock one in my X3. If we forget the balancing problem (please do), what specs do I need to look for? I need a 16 mm or 20 mm lens with M12 thread.
I read that I need to look for a IR cut lens, but looking on aliexpress I get confused, what does the following all mean?:
1.2" 1/1.8" 1/2.5" (I guess sensor size, but will only one work?)
2, 3 or 5 mega pixel lens (how are they different??), fixed iris, hd ip camera, ccvt.........
So which one will work? Are the $10 China lenses the same as the expensive ones sold locally? They all look a like.
