Fred,
I may have misinterpreted the information.
But in your initial post you listed the KAF1102 FOV as 37 x 55 but then the 16803 as only 37 x 37 - should that not be 55 x 55 ?
Assuming the same image scale.
If so - you have more than halved its area !!!
That might make the difference you need to justify its purchase
