Classic portraits are as much the strength of the Makro-Planar T* 2/50 as the most striking details from close up. Thanks to its high performance at any distance, this macro lens can be used for a variety of tasks. As one of the fastest macro lenses available, small details can be isolated from the foreground and the background for great creative control.
