Folks with experience, can you help choosing the right macro lens for a FF camera?
I was thinking about a 100 f/2.8 IS L as I could also use it as a portrait camera when I am hiking, but I have reviewed my favorite macro photographs and I noticed that they were taken with 150-180 mm lenses. Or with 100-105 mm, but on a crop camera.
I was thinking about Sigma 150 f/2.8, but I read about AF issues.
So what is the ultimate lens?
