[QUOTE="Bengt Nyman, post: 476304, member: 13692"] Excellent question. According to existing tests we know the following: Tamron @600: DxO 12 PMP, LenScore resolving power 729, LensTip image resolution 36LP/mm Sigma S @600: DxO -------, LenScore resolving power 884, LensTip image resolution 38LP/mm Nikon 300@300: DxO ------, LenScore resolving power 924, LensTip image resolution 42LP/mm Assuming that the TC20 reduces the resolution by a rumored 27% we get: Tamron @600: DxO 12 of 36PMP, LenScore 729, LensTip 36LP/mm Sigma S @600: DxO -------------, LenScore 884, LensTip 38LP/mm Nikon 300@600: DxO ------------, LenScore 677, LensTip 31LP/mm This alone suggests that the new Nikon 300 with a TC 20 can not compete with either Tamron, Sigma C or Sigma S.
