Title: What I have been missing
Review: I cannot believe I didn't try the Canon L series before this. Nothing against my EX Sigma lenses but the upgrade was way more than I expected. The focus is lightning fast. I took hundreds of photos at a night high school football game and was VERY impressed. Low light photography is my achilles heel but this lens has allowed me to get the shots I have been missing. I loaded the photos for some editing after the game and realized that no color or contrast corrections were needed.
