Google. It is a bad, bad habit.
Somehow I came across focus-stacking. This lead me to focus-stacking landscapes. Then to focus-stacking macros. Then to the best macro lenses. Then to other uses for macro lenses. The Tokina 100mm f/2.8 macro looks like a great lens for portraits as well as macro.
Before I spring the $450 - $500 for the lens, I would like to see if others have used it and what they used it for? I see it as something to replace my kit 55-200mm as well as having the macro aspect.
All advice and comments gratefully accepted. Cheers.
