I really love this lens for indoor glamour/boudoir shoots in confined spaces. If I go to my 28mm lens, there tends to be too much distortion of the body proportions. 35mm is just right. The Image Stabilization is nice to have when working indoors under available light and the F/2 aperture gives a nice background blur. I'm sure the 35 L2 or the Sigma Art lens are sharper, but if you are photographing women, you really don't want them to be ultra sharp. You can still count the eyelashes, that's sharp enough for me.
