<p>Does anyone have opinions on the image quality differences between these two lenses? <br>
There is a decent price difference in the used market with the FD lens being approximately $1,200, and the Nikon priced near $1,500-$1,700.<br>
I have a Nikon 400mm f/3.5 that I like very much, so I am experienced with manual focus long lenses. I'm just looking for something with more reach and decently wide max aperture.</p>
