I was convinced by Robert Stech's website and bought a Vivitar 70-210 Series 1 version 2 (the one Manufactured by Tokina) I saw this as an affordable way to get a fast good quality zoom. I'm quite happy with it, just a question, is there any way to "activate" the macro capability? The other "macro" zoom that I have (cheapo sigma 70-300) has a switch to use the macro mode, but in the Vivitar didn't find anything like it.
Thanks
