Im not sure if this is the place, but this is my first post, so here I go Im working on a CCTV camera that has a 1/3" cmos sensor This guy http://www.ueye.com/frontend/catalo...le=menue3&form_KatID=5&nav1=25&nav2=59&nav3=5 But the lens that came with the system is a 1/2" lens This guy here http://www.tamron.com/cctv/prod/12vm412asir.asp My problem is that I need a wider viewing area. I need to mount the camera on a car and the field of view isnt wide enough for my application. The lens says it has a field of view of 93* which should be good, but when I actually measure the FOV, its only like 63* which doesnt work My question is, what happens when you put a 1/2" lens on a camera that has a 1/3" sensor. If the answer is a smaller FOV, then we are going to need a different lens that matches with the camera. I have no clue about lenses and cameras and the like. Is there a quick FAQ for this stuff? I wasnt able to find anything when I did a quick search.
