This lens would have to be one of the sharpest I have used, its better than my 80-200 2.8 at 300 when stopped down a bit, I dont know wether its the abresion reduction, but for a non ED lens its the goods. The AF speed is awsome on the 300s and it dosnt hunt like the 80-200 when its lost.
Still getting used to the push pull


Ill post some pics when I get some online somewhere.
