Working Distance (lens front element to subject) often determines the best focal length of a portrait lens. A long lens (150-mm) may work well outdoors, but be too long for a small studio. A shorter lens, such as 60-mm, may place photographer too close to subject for comfort. Circa 100-mm lenses are popular for both macro and portrait.
Those focal length guidelines are for a full-frame sensor, right? They should be scaled down by 1.6x for the T3, so the 60mm lens would hit the sweet spot.
