Just a few words about the index. As we have Gordon's excellent references for the Canon Lens Listing
and the Nikkor Lens Listing
I took the opportunity to unify the naming convention for not only the names in the index above but also in the associated threads. This seemed particularly apposite for the Nikkors as some thread titles included NIKKOR at the end, some at the beginning and some didn't include Nikkor at all. So that left me with a decision to either excise the word Nikkor or have each thread start with "Nikon Nikkor". In the end I opted for the latter on the basis that the lenses are so good they named them twice.
Lacking any such reference for the other makes of lenses I left those strictly alone so any ambiguities are down to the thread originators.
I hope the index proves useful and if you see any errors or omissions then please PM me and I'll try and put things right.
