So, has anybody tried using face detection with a wide open lens and got good results?
Tim1970, first off, apologies for taking two days to get this done. My wife... blah, blah, blah (it is ALWAYS her fault
).
OFFICIAL DISCLAIMER!
I do not shoot people wide open. I think razor thin DOF for portraiture is way wrong. I NEVER, EVER, EVER! posted any photos of my wife with no makeup and her hair not done! GOT IT!
Anyway, I used my 80D and 85 1.8 wide open and 50 STM wide open. Settings: Face detect LV, AI-SERVO, f/1.8, 1/250, ISO 200, bounced flash, JPG STD, focus distance was 6-8'. I was surprised to see how quickly AF responded to little movements. I was surprised to see the AF change the number/placement of little squares as her hand/phone went into an out of the AF area. The camera was very good at NOT picking up the fingers/phone. It kept the AF on the eyes, and whatever else it deemed 'face'. The crops clearly show that the Face Detect AF does NOT focus on the end of the nose, but seems to go specifically for the eyes. At f/1.8, on this angle, both were NEVER going to be in focus. I think LV Face Detect on the 80D does what you'd want it to do. I am not a LV shooter, so weigh my opinion carefully. It may be worthless.
