I agree with spending more money on a lens is better than spending more money
on a body,
especially with a 300mm, 400mm etc prime lenses. The difference in quality of
photos between my
tamron 70-300mm and my nikon 300mm is clearly visible to the naked eye and even
with x1.4
converter on the 300mm it blows away the 70-300mm.
I know macro extension rings only work to a certain f-stop but my nikon 300mm
and the x1.4 still
works at f8 etc.
cheers, simon muirhead
