Not lots of manual focusing, but what I do is of wildlife, so I don't have much time to do it. I've been doing this since I was 8, nearly 60 years ago. It seems that the more things become automated, and the lazier we become in the drudgery of things like focusing and getting exposure right, the less we pay attention to the craft of our art. I think the two aspects of photography go hand-in-hand, and less work in the craft aspect leads to laziness overall. I have always distrusted AF, and still do. My thought is that AF exists mainly to sell more expensive lenses. That's probably more a product of my fertile imagination that reality. I hope this rather abstruse note hasn't lost you, and I am going to pursue a focusing screen outlet I found in China. Maybe that'll pan out.
