I listed my 50-135 at marketplace twice, and withdrawed twice..
I always want to switch to 70-200 f2.8 or even 60-250 f4
but really 50-135 focal length is still very useful than 70-200 for me and f2.8 is a lot useful than f4
and the size and weight is another major plus too.

By the way can someone give a sample showing focal length difference between 135mm and 250mm?

but the DA*60-250mm doesn't zoom in that far for short to midrange distances when zooming from 200mm towards 250mm, so compare it with the 200mm range.

The 50-135 is f/2.8 vs f/4 for the 60-250 so you have an advantage in low light with the shorter zoom along with the differences in DOF between the 2 lenses so they aren't completely redundant. I have a pair of manual 135's. One a f /3.5 and the other f/2.8 and both are can be killer portrait lenses wide open. Having a high quality AF zoom in that range is desirable. I'm kind of in the same situation. I don't do that shot often and my MF lenses have me covered if the need arises. However, if I owned the 50-135, I don't think I would get rid of it.
