I have tested with f4 it is perfect but I bought that lens to avoid using a tripod
To be quite honest, if you expected to do this routinely without a tripod you have a little bit to learn about camera handling. (THough it seems your steadiness is not the problem, really. Not bad) Not to say it's impossible, but you may well be complaining about the tech when you've got some skills to work on. Don't be ashamed, there: I *pride* myself on this kind of thing and after thirty years I don't always hit like that, even with SR.
It still appears you're focused short, so, focus a little longer (more distant) and then tell us how you do.
That lens in general is quite good wide open, but you don't actually get infinite DOF out of hyperfocal anyway. (With faster glass I prefer to stop down to around there if I can, anyway.)
It does still look as though if you had another issue, your unsharpness would be more directional, so, if shooting that lens wde-open, choose your focus point and achieve it.
(If you're relying on autofocus, it may take a correction, but in that light I really suggest manual. )
