Clear pictures - help requiered

Thank you for your help Nick. And yes you are right, the AF point was at the center of the picture, somewhere on one of the windows.

I think i might be a bit too picky when it comes to pictures? I see all you guys making such sharp and amazing pictures and then when i look at mines i get angry because they are not as clear (some of them at least).

Again, thank you for you advice. It is going to be well used.

Best regards,

Iris
