Using teleconverter, the aperture would reduce.
1.4x used in a f2.8 lens becomes f4 maximum
2.0x used in a f2.8 lens becomes f5.6 maximum
adding another 7-8 glasses elements in the optical path will reduce quality.
The 300mm f4.0 is a simple design, have less lens elements than the 70-200mm zoom and have less distortion.
I also have the 300mm f4 Nikkor and the quality of the photo it takes is very good and it weights about the same as the 80-200mm f2.8 zoom. |
