Hi Guys,
I guess you missunderstood me. I did not say it does not focus to infinity. What I wanted to say is that it is very difficult to focus on Infinity with a Macro lens. That is all.
If it is already difficult to focus a 500mm f4 Canon lens on Infinity now imagine focusing with a Macro lens ...
Well it does not cost much to buy a Macro 180mm and try it
but afterwards you have a lot of experience and that is worth it
