To(...)Seriously, why on Earth would anyone want to stop a 35mm format portrait lens down to f/11 (if I reads you correctly)?
In a 200x300px pictures, it's OK at 2.0. On 50x75cm not.
Even at 11 you have 3D effect if you blow up to 30x40cm, F 11 allows you to have the 2 eyes, hear sharp. It's important that cloths, jewels and harms are sharp for special orders.
