Is there a REALLY effective way to get more Zoom from a Pany 100-300mm?

My 75-300 is very sharp at 300mm, yet many images taken at 300mm have been disappointing, clearly because of heat-induced turbulence. It not only hampers sharpness but also makes it harder for the AF to nail the focus.

Slowly learning to use the Olympus OM-D E-M5.

Paul,

That has always been my experience too,....I find the shots at 600mm or close to that show the "turbulence",....nearly always requiring increasing the contrast to make them acceptable.
