Aperture Reading - borisbg - 10-19-2013

Hi Zoners, I need your advices on this:

I purchased used Sigma 150mm f2.8, tried it on arrival and it can't open more than 3.0... Sometimes 3.3. Otherwise everything else works. Is this easy fix? Should I keep it? Or more surprises might come?

Two threads for one theme?

See my answer in the other thread.

Eventually, terminate this thread, rather than

discussing the theme in two threads.
