No Matter what ...Learn DOF My new friend, It's not rocket science.. you let any Camera think for you You will always have Issues.when You get it down. you'll never be OOF again unless, Your holding Your camera Wrong and at every workshop I've done from Florida to Hawaii. It's extremely common. #1 issue at Every workshop Or seminar, Or Lectures I do On commercial work is focus. all I have to do is watch you shoot and Can fix it. and once you get it. you will say.....You gotta be kidding.....Trust me. I have No reason, Nor have I ever changed My ISO from the Lowest unless it was for a effect.. Shutter speed ,Speedlight or a tripod which BTW is the second Most Important Piece of equipment you will Buy. A tripod and Good Head is critical. Not some cheap sticks. Buy the best and You Buy Once. watch this. Joe Is One Of the best PRO shooters out there and a very Old friend.
