>The other way I could go is to buy a 70-210mm or 100-300mm. For sharpness, >open or almost open, what do users of these lenses recommend? Or the ED 70-300 1:4-5.6 D. Good wide open, excellent one or two stops down. Also light, a delight to hand-hold (that's the big plus for me) and relatively cheap. Highly recommended. Regards John Bean
