in my case 35f2 AF-D paid it self zillion times over all those years.
When i was younger I had only 50f1.8 nonafnond on full frame. I cannot stand that focal lenght now but am sure i could go by if i would try. You can do pretty much anything with that lens.
third place would be tight between 14-24 (i had my wide times), 85 and 200/2. Everytime i take 200/2 for a shoot it generates $$$s in post sales, it is probably (except maybe 14-24) only lens regardless of costs which cannot be reproduced by anything except those. So sad that 200/2 is so huge and i cannot use it as often as i would like to.
