Hi Boris I think it is not only a question of DOF whether the background of a picture adds or distracts. A smaller aperture will help, but not always IMHO. I would try to move (myself) more and take several pictures from different angles with that lens at F5.6. With moving targets, making a series of shots instead of a single photo could help having a good one among them too.
But, there must be better answers from the pros here ;-) greetings Markus >> >>MM> Hi Boris >>MM> I like the expression on most of the faces but I think you really >>MM> should take care for the backgrounds too.... and the framing is >>MM> not perfect as well on most photos. greetings >> >>Markus, I have to agree with you.
