Hi folks, In a few threads, focus tuning for sow fix camera/lens combos has come up. This topic interests me. I have one lens, a 50-200 SWD that is fine by itself, great with the EC-14, but awful with the EC-20. I was wondering if there is a solution for this combo and maybe for others having similar challenges with non-m43 lenses. It's a topic I know nothing about, assume there are others like me that would benefit from a single thread of info. So post if you know. Much appreciated.
