Hello. Im planing to pair Nikon 80-200 f4 Ais + Nikon TC-200 teleconverter, so I was wondering is this combination going to work? My biggest concern is that Im getting (if Im right) 160-400mm f8. That f8 is biggest concern for me. I guess that I will have to use it only in bright sunny day, so I can manage to get at least 1/400 for handhold shots. Right? And I have one silly question, because I have never used teleconverters before. Im familiar that x1.4 change aperature for one stop, and x2 changes it for 2 stops. So, if my lens aperature is at 4, and I put x2 converter, I will get f8. But, is lens going to performance good as stoped down to f8 without converter? Or it's going to performance as f4, but with less light (f8). Im little confused. Thank you.
