I can only tell you what I have found through experience. Yes, the sensors are different, the F5 and F100 use the Multi-CAM 1300 module while the F80/N80 uses the Multi-CAM 900 module (consumer grade, but newer design). I do a lot of shooting along the ocean - I live in Hawaii after all - and have found that the F5 has trouble locking onto ocean waves, it does a lot of hunting, and I usually have to turn it off and focus manually; something I rarely have had to do with the N80.
