I have the Canon 70-300mm IS. I'm going away in a few weeks & want a lens that will take me from about 18 or 28 mm to about 100mm. Maybe 18 to 50 if that was the better option. I don't want to spend more than £200-00. I am very happy with the sharpness of my Canon Lens at all settings between 70 to 300mm, so I want a lens at least as sharp. If there was a good lens with IS at a little over that price I would buy it, but I expect there won't be. Can anyone advise me on a lens that will meet my requirements?
