Hi All.
I am fasenated with telephoto lenses. I have a few including the Big Mama for the four thirds because my three cameras are the E-500, E-330 and the E-420. Recently I purchesd the Opteka with the four thirds attachment. I took some photos using a good strong tripod and remote not to touch the camera at all. The results were not that bad considering the dust in the air in summer. I am now waiting for authum/winter for those crisp clear days to try it on the super lage turist ships or birds in the country. Has anyboby got one of these lenses. I bought this from the US.
