Im unsure which on to get, It will be used with a D90 and a Nikon 70-200 VR. I have been thinking about the Nikon 1.4 or 1.7. As from what i have found on the internet the 2.0x results in alot of softness. But then a few still say the 2.0x still gives sharp photos. The main use will be for motorsport, so i dont think i need to go for the 2.0x
But what are peoples opinions on the 1.4 and 1.7. The 1.4 is supposed to be as good as the lens itself, losing an f stop or 2. Would the 400mm it provides on a DX body be sufficent?
I was going to go with the 1.7 but from searches on the net some people say that its also soft and the results arent satisfactory. But others say its sharp.
Has anyone got any examples between the 1.4 and 1.7? or what are your opinions?
