Several months ago, I got my G-2 with 3 lenses, including the 28 mm and I am considering getting the 21mm lens. I have seen some photo's shot with the 21mm on the Web, but not many. From my review of many web sources some of the advantages of the 21 mm over the 28 mm is wider field of view (90 vs 75) and better depth of field). Users of the both lenses: do you feel that the greater field of view and extra depth of field justify the cost? Are there other reasons to have the 21mm? Are there other s&le photos with the 21mm on the web that I can review. What do you recommend?
