I've gradually moved up the scale of Canon lenses, and each time (for some strange reason) find myself surprised at the continued increase in quality.
The move to this lens has convinced me that I need to move to an all-white, all-prime collection.
I simply love using this lens on its own or with 1.4x or 2x TC.
It's sharp. It's quick. The images are a treasure.
You won't regret buying this lens.
