Rob and I went to the camera store today, after I did some research on wideangle zoom lenses. Ended up buying a Sigma 10-20mm F4-5.6 wideangle zoom and a Sigma 70-300mm F4-5.6 telephoto/macro zoom. And filters. And a camera bag.
I really am a big fan of wideangle shots. This and the 18-70mm will be my standard “walking around” lenses, and the telephoto and my fixed focal-length macro will be for special occassions.
