A wren

Wondered what lenses to take to Hartsholme park today , for some reason I took the macro and my shorter telephoto ! Another photographer I bump into sometimes reckoned the in built 2X Olympus converter was fine, But I tried on a few subjects and I disagree . This wren was with out the teleconverter but I wish I had taken the longer telephoto . Lesson learnt Long telephoto and macro next time :-)
