Isn't it great when the repair you want to do turns out to be simple and can be done quickly?I had a friend who was one of the better pro, wedding photographers in my area. (He got the big "C," and passed away, very young.) His trick for soft was stretching a piece of bridal veil over the front of his lens.
Show some shots from the lens once you accumulate some that you like.
I like a good 135, but finally sold off my Nikkor 135/2 AiS because I don't need a soft look at 135mm.
