It could be a good shot but one thing that I learnt about using the TELE or ZOOM lens, as the focal lenth gets hiegher then the shutter speed must increase for example if I have a 250 mm of focal lenth then my shutter speed must be hiegher then my focal lenth but here the f number resists and if my 250 mm have the f number of 5.6 then I must push the f stop two step down. umeed waram key roushan shuda basheed, TFS.
