i dont have a lot of extra money to spend on my hobby but i have saved enough to buy a used Canon 70-200mm F4 Is lens ...which i already have....and i am looking to buying a Canon extender......one of the 1.4 Ext.
is there a difference in the 1 vs II Canon Ext? all i can find is a few coatings and weather proof....should i get the II for a few dollars more?
i shoot a Canon T2i and my lens is a Canon 70-200 mm f4 IS........
