I would like some feed back on this lens. I will be doing a lot of travel in the next year or so in Australia with a camper and 4x4. I have a short tele, a wide angle and the 50mm. On the wife's canon she has and old 75-300mm and the 18-55mm. I am looking for a macro for the small stuff so I would like your views on this lens. Like all of us, the budget is not that flash.
