It is fickle. I have found that it's a touch of luck sometimes honestly. With the Sony A7Rii I can use the focus assist to try and dial in the focus more accurately. The main problem is @ 0.95 any type of sway or body movement from the photographer or the subject may cause the capture to be either soft or oof. It is really frustrating but so rewarding when you do nail it completely. With a model that is cooperative its one thing, but a child or random street shot, you kinda have to take what you can get. I just can't stop it down. It's almost an addiction. My best results have been from shooting multiple exposures and really focusing on my body movement and breathing when I press the shutter. There is a shot of my setup.
