You need to get further away or increase your depth of field by selecting a smaller aperture (maybe f/5.6 or f/8).
Of course is this lens for portraits. But what am I doing wrong?
I don't know wether I may post this question here but there I go.
I have to make some photos at my work. Today I took a few, but I didn't manage to get both ladies sharp. What am I doing wrong or do I really need another lens for nice (bokeh) photos?
