ok just got this lens anyone here using it on there canon or nikon? if so would like to ask you how you like it and if you have any pointer using it..or pics to show ..so far it is amazing compared to my 28-135 that came with the 7d man the close ups are awesome but definitely need the tri-pod to shoot as A more than steady hand is needed unless you are shooting multiple frames per shot and weeding thru the bad ones and keeping the good as i am doing to test it..will post some shots after I master the lens. until then post yours would love to see them..
