Hi, all. I hooked an Olympus 70-300 four thirds lens to a Pany MA 1 mft adapter and started playing with it on an EM-5. This combo is giving me the slowest autofocus I have ever seen. The focus runs all the way out, sometimes twice, before it settles in. I planned to use this setup for a safari next month, anxious to have a 600 mm equivalent. But there's no way this setup is going to work unless I convince the wildlife to pose for me. Has anyone else run into this situation? I'm thinking I may have to bite the bullet and get the 75-300 MFT Olympus or the 100-300 Pany. Thanks in advance for your ideas....Ed.
