This is a truly perfect lens for everyone eager to dive into the world of the macro, but more with its 105mm it is also the perfect lens for portraits with a definition that largely fills my expectations. Both in Auto Manual, it is very efficient especially associated with my Case "D90", it complements the widely 18-105mm and 70-300mm. However, the negative points are firstly its price can vary between 750 and 900, which certainly dampen much (like me) before deciding to acquire it, and its weight that requires a foot (therefore) or habit expert especially for shots of moving subject. The quality of this objective forget these last two points from the first pictures.
