Ive never really tried it, but ive seen amazing results, of flowers and insects and generally everything small. But have many questions . Its a lens that i would like to add to my collection, but have no idea what i really want or what would be best. Yes, i know it depends what i want to do and how close i want to get, but i thought id ask the people that know. Ive had a good read on the Sigma site... www.sigma-imaging-uk.com/lenses/macro/macro.htm I see the 70mm and 105 mm are much the same price, do you recommend one more than another, whats the most common lens? I think comparison pictures the difference between 50mm, 70mm and 105mm would be nice. Currently i use a Canon 350D, so do i need to watch the crop factor when chosing a lens? Do you need additional lighting, or can 90% of nature macros be done with natural light? Do you recommend any lenses, lengths, makes etc, i would like to pay as little as possible, but maybe £350 (If i can get a decent lens for that?) max. This is as good as ive got with the Kit 18-55mm, which im happy with, but you cant help feeling a macro lens would have made life so much easier and turn a snap into something amazing. Hope you can help... ive tried to keep it quite open so it might halp others wanting to start macro photography.
