Hello everyone. Let me frist start off by telling you that I pretty new at digital SLR photography and already I'm frustrated . I am looking to buy a wide angle lens and/or telephoto lens for my E500 however I am not willing to spend a lot of money on them either. I do not intend to go professional, but still want the ability to produce different effects. I'll even buy thru ebay however I just don't know what fits my camera or what I need to get so that certain lenses can fit onto my camera. I saw on B&H there was a wide angle lens for $99 (Sigma Zoom Super Wide Angle 18-50mm f/3.5-5.6 DC G Autofocus Lens for Olympus Digital Cameras (Four Thirds System)...is this something I should look into or should I not waste my time on it? I just don't want to get duped into buying something expensive and don't need. And for the telephoto lens, I saw this at B&H - Sigma Zoom Normal-Telephoto 55-200mm f/4-5.6 DC Autofocus Lens for Olympus Digital Cameras (Four Thirds System).
