I'm thinking of buying the Sigma 120-300mm f/2.8 ex dg os apo hsm af Lens and 2x teleconverter.It's lighter than my
Sigma 50-500mm that needs a tripod and the 2x will give me the reach.The f/2.8 gives me plenty of light and even
with the teleconverter on at 300mm the Ap is at f/4. So why do I have doubts about this lens giving me sharp shots.
