When I purchased the 80-400mm lens I saw two reviews from users who also fitted the same teleconverter. It is a major step forward in design and now I have seen the results I understand why they charge £450 for such a small and light bit of kit!! It has 7 elements in 4 groups including elements with fluorine coatings.Nikon have done a 1st Class job on this it may mean loss of sales for them on the long 300mm to 800mm and costly prime lenses! As stated by Nikon there is no loss of any auto focus or exposure functions of AF-S lenses. They say that it needs a stop more exposure. I think it is even less than that I only made 1/2 stop to correct and match the two images. Last edited on Wed Mar 4th, 2015 05:15 by Graham Whistler ____________________ Graham Whistler |
