hehe yah, that's a monster of a lens, and it comes with a monster of a price. Also, i don't have monster arms, so that thing is defiantly out of the question.
to answer what i intend to do: basically city birds, and other city dwellers mostly. I'm looking for something long, 300+ and whats cheap(er) (and i generally dislike zooms, because zoom + cheap spells unusable image)
i was looking at the Sigma sight, it has a few things (a 300, and a 500), though i cant get a hand on the price of them.
Tamron or Tokina? no clue
and figuring out discontinued 3rd party lenses is impossible! (or im just not very good at this whole google thing)
