hey, i have a question about a photoshoot im about to do.. im taking portrait pictures of a couple at a park. and i have a rebel xti, but just the kit lens and no flash (noob). i have reflector, lens hood. i want to know what would be a good lens and flash for this type of photography? theres a catch tho: i also want to have a macro lens for the future. what is a good versatile lens that can be used for macro and portrait pictures. i want to take picture of little bugs eyeballs and stuff, haha. i know the flash depends on the lighting, sunny or cloudy, but i just want a good fast flash. maybe a picture of both a macro and portrait shot with the same lens would be cool... no price limit, im ballin right now, haha. thanks in advanced.
