Hi Guys, I've been tearing my hear out to find the right wide angle lense to buy. I am travelling to France at the end of the year, and am wanting to buy a lense to take shots of buildings and landscape - but also take photos of people close or far, without having to change the lense everytime. I've been told that the smaller the number (i.e. 18mm) the wider shot you'll get. So i went looking around and most of the "wide angle" lenses and found something like this: Sigma Zoom Super Wide Angle 18-50mm f/3.5-5.6 DC Autofocus Lens for Canon EOS Digital Cameras When i bought my camera - it came with a Canon EFS 18-55mm & Canon EF75-300mm Lenses, does that mean that i already have a wide angle lense?? I have no idea what i'm doing - things are getting more confusing by the minute.....can anyone please help me clarify what would be a good lense to take photos in France??? Cheers, Roger.
