Hi Jinx :) Of course you're right with saying, the more expensive stuff is (usually) the better stuff :). I do believe any word Donald says (not only because there are a lot people out there, saying right the same) but if i do need a zoom lens and don't have 1600 (100-400mm) or even 2000 Euro (for that great 70-200 L IS) i'll have to stay with what i can afford. At least i get IS ... after Donald told me, how happy he is with it. I'm not sure if those other lenses are three times better than what i will be buying (how to measure that exactly?) but they are three times as expensive. So i'll have to stay with the lower one, knowing that i don't have the best i could get and trying to make the best out of the limits, that inferior lens gives me. If sometimes taking photos gives me some real money, i'll think about that question again. So thanks to you too Jinx :o) As an info to all you helpful people: today i gave my old zoom-lens back to the dealer i bought it some weeks ago. He's nice enough to give me the full money back. And i ordered a 70-300 4-5.6 IS USM. Will get it within the next two weeks (hopefully!!). If anyone is interested, i'd give you information on how happy i will be with this one. But as it is better than what i had, i will surely not be too disappointed .. just should never ever think of that L-series again sigh ... but what is a man without dreams? :) Thanks again to ALL of you! Hope, sometimes i can give something in return! :-)
