2010 butterfly shots, I used 105 mm and 1.4 TC.I got very good results. 105 mm is not always successful for the butterfly shots. Some butterflies until you make shots, fear flying. 150 mm, more advantageous in this regard.
Monetary conditions, if appropriate, will be released, which Sigma 150mm F2.8 Macro Stabilisation get with optical.
