[Arsonism]

I wanted to make this thread for three reasons:

1) To see if anyone on the forums has the version I or II of this lens and their experiences with it.

2) Would this be an exorbitant amount of lens for a Canon T6i

3) I didn't see another thread of this kind through a good bit of searching, and I wanted to double check myself before investing.

Currently I only have two lenses in my arsenal, Canon's 18-135mm (which has shot amazingly and I'm very happy with) and Canon's 50-250mm which has resulted in a nightmare worth of chromatic aberration. Personally I'm looking at jumping further into nature and sport photography and I really don't see the point in short changing myself. I have an option to purchase this lens under a no interest financing option and it seems more than feasible even in a slow income time for me. I just wanted to check other's thoughts and opinions on trying to reach the "next level" world of nature/sport/active photography.
