NO CRITICISM TO BE GIVEN ON THIS OBJECTIVE; IT CORRESPONDS ENTIRELY TO MY EXPECTATIONS; THAT'S SURE AN OBJECTIVE WHICH IS USED MAINLY IN TRIP BUT I MUST SAY THAT THE result is stunning !!! VERY PRACTICAL AS IT ALLOWS Do TAKE ONLY ONE GOAL FOR PICTURES THAT GO TO THE OBJECTIVE OF TELE WIDE ANGLE WITH QUALITY IMAGE STABILIZATION WORKS ALMOST EXCEPTIONNELLE.LA VERY WELL AND IS USEFUL IN CERTAIN SITUATIONS FORT. JUST A LITTLE LACK OF GAIN FROM 250 TO BE CORRECTED BUT EASILY WITH REFLEX QUALITY AS MY 7D. IT IS FULLY COMPATIBLE WITH MY CANON 7D. IN SUMMARY, I RECOMMENDED PURCHASE THIS TO ANYONE WHO WANTS FROM 'LIGHT'. "
