I've never thought that you had any focusing issues but these ones don't even compare to your newer photos. Your recent photos are definitely an improvement in composition, exposure and focus. In the first one she looks soft all over....Did you do any masking in elements on these?? There is a halo effect on a few of them which is usually caused by masking. But anyways,
How you did this? By having your camera on AF-A and auto area AF. The camera was probably choosing your focus points for you. It will choose the best focus point and the use surrounding focus points as well. You can get in focus shots like this but....you can't selectively focus on what you want. Honestly, it was probably just luck that you got the shots with the eyes in focus. I've been going through my photos and getting rid of a bunch and I found that I had a lot of perfectly focused ones but I had more OOF ones. On portraits I was zooming in 100% to see if they were sharp and in focus. Sometimes, on smaller images, it make look like its in sharp focus but when you zoom in - its not. The thing is - its a lot harder to work in any modes except the automatic one. You may feel like your having issues, when previously you didn't, and its because its a skill that needs to be honed. But....I've never noticed that your pictures were out of focus. Yes, some of your photos will be OOF and some won't. Toss the OOF ones and be happy for the keepers. Eventually you will have more keepers than ones in the trash. You will definitely have a lot of pictures deserving of the delete button while shooting wide open. Remember, I told you that if you want to shoot wide open -go for it because its great practice - but beware that most of them will probably end up in the trash.
Can I see one of the out of focus pictures? You can send it to me on FB if you don't want to post it here.
