OlM-D with converter and 300 mm 2.8

Total 1200mm , a first try. Not to happy about it. Rather slow autofocus and not suitable for small moving birds. Rather stich to the E5 or E3 with this lens. But de 75-300 works fast and very surprised by rthe results. The Sandwich Tern in the air is a lucky shot, perhaps practive will help. Camera is used on a tripod and gimbalhead
