MACRO CHAMP: The Most Bang for the Buck

I have shot 4 different Canon macro lenses (100 f/2.8, 100 f/2.8L, 180 f/3.5L, and the MPE-65) over the last 8 years.
I have typically held the belief that moving to a 3rd party macro lens was a step down (if not in image quality, in build quality).
However, all of that changed after reading enough reviews on the Sigma 180mm f/2.8 EX DG OS HSM APO macro lens, and after purchasing it, I can honestly say it's the best macro lens I have ever put at the end of my camera.
So I thought I would create a blog post


Enjoy,
Jack
