70-300mm NON-APO lens This and next photos as lens samples on "kit" lenses: 18-50mm DC and 70-300mm non-APO, both inexpensive lenses vs EX lenses, and less sharp than EX. Used these lenses rather than the EX lenses I prefer 50mm EX, 28-70mm EX DG and 105mm EX DG because of discussion at this photo time on the Sigma users' forum at http://forums.dpreview.com/forums/forum.asp?forum=1027
