I've just checked up for lenses for canon cameras and they are quite expensive if contain IS feature. However ones which don't have this feature such as sony's lenses, are not expensive as much as canon's. Now i wonder that if i buy a lens without IS feature, is it too hard to use it without tripod ? I thought that rather than buy a canon camera , it's better to go and buy a sony camera with "super SteadyShot" feature. Thus i can save money with lenses which i'll buy later. What you think about that ? I'm very indecisive between sony and canon. If i choose canon, i'll buy 450D , if choose sony , alpha 200 or 300. Also if you comment these two camera, it will be good.
