Thanks all, I very deliberately kept the centre focus (I very often use the multi selector to change the focus point to suit) as I wanted to test sharpness with the micro adjustment I made and it seems +20 is as close as I'm going to get. It is still front focusing, but is so marginal, I'm not going to lose sleep over it. I'd never normally cut legs off unless I'm going for a tight crop.
As for the edit, it is personal taste and I'm still learning photoshop, but do like the high contrast look....I need to just get the finger out and learn Photoshop, but the courses are so so dry to watch....lots of coffee required!
