Yep... see that's the type of advice I need.. simple reality checks and voices from experience. I'm just making sure that the issues/problem is me and the inexperience. I wanted this lens in the worst way and found a way to acquire one and now that I realize ...holy $&%^ I spent a bunch of money I want to maximize it's potential. Where I live getting close isn't always possible or even an option. Lesser lenses were not making the grade.
I'm also heavily weighing the options of going FX.
