Yep... I've tried to work the Winogrand way back when I used Leicas. I felt it was a better method with 400 (or pushed as he used) speed B&W than with crystal clean digital. I find that digital shows missed focus a bit more than grainy film. These cameras AF so fast these days that I actually find it a convenience.
The XF10 has a dumbed down version of snap focus. It will set the camera to 2 meters and F8 or 5 meters and F5.6. The Ricoh GR lets you choose many different meter increments at any aperture. Some people swear by this, but I still prefer to focus on what I want to be in focus.
This is interesting stuff, the way people work, that is. When I find photos I like, I'm always interested in how they were made. In my work related stuff , it's expected that I deliver sharp photos; if that's what's called for. My personal photos lean in the sharp direction, but not always. Most of the time, I want to be able to predict the results. I still experiment with new things.. getting them down, so I know what to expect. With AI devices, I don't always know what the camera brain will do. So, I tend to turn a lot of that stuff off, unless I know pretty much what will happen.
As you know, from seeing some of my old work, I often treat a SLR/DSLR like a view camera. The camera is on a tripod a lot. But, I've been known to, stick a Nikon MF camera out of a moving car window, at a slow shutter speed too. I get things I like doing that in the right environment.
The first thing I look at with a new (small) camera, is, how much of the auto stuff I can turn off. Number one is auto flash, number two is AF, three is AE. I use those features, but, want to decide when they're needed.
