That's a very expensive filter we're talking about here, right?
Canon has the 500D which is expensive but without the thread size I require (67mm).
For beginner's sake, I'll just start with Hoya or Tokina... I'll take up the Canon / Nikon with decent primes if I'm really addicted to it.
I understand that we focus to infinity and use the close up. What kind of close up distance do I need for insect shots so as not to scare them away? Macro experts please advise.
