I love my old Tamron. I get some weird satisfaction using such an old lens. I always figured someday I would move to the MPE-65, but I wanted to be dead set sure that macro was something I would keep on enjoying. I don't really have any inhibitions about the focusing because all I do is set my Tamron to 1:1 and move my body anyway, so I feel like I'm set on that front.
When did you feel as if you had to have it? I get frustrated I can't get past 1:1 sometimes, so that's why I want it. But I'm not sure if my abilities are advanced enough to allow it.
So what made you take the leap?
