G'day guys! As the title says.. am I having focus issues with my 80D? Recently I purchased a canon 80d and sigma 18-35mm as my upgrade coming from a 700d. First thing I noticed was back focusing (further than intended focus point) using the sigma lens, minor at 35mm but ridiculous at 18mm. I did sort it out as much as I could with in camera micro adjustment. What I did find odd was even in live view shooting it was mis focusing with the sigma 18-35. At first I thought "oh never mind it's the lens" but then it got me thinking.. Live view should always be sharp no matter if the lens has focus issues. So I went ahead and mounted it to my 700d. As I expected, shooting using the view finder resulted in out of focus photographs however in live view the 700d had crystal clear shots. So why didn't my 80D have the same results using the live view mode? Is duel pixel AF off?? Can someone shed some light on this? I will add that I have a 55-250 kit lens that I tried on the 80d.. results looked fine, both in viewfinder and live view mode.. Odd results!
