Been using SLR cameras for almost forty years. Started with Cannon ftb, but now I have an Olympus E-30 and E-510. My main interest is Wildlife, but my specialities are birds in flight and Arthropoda, naturally, using macro. I have four lenses which because the 4/3rds system doubles the focal length to cover the range 28mm to 600mm. They are : Zuiko 14-42, Zuiko 40-150, Zuiko 70-300(macro) and Sigma 105 Macro.
