.......having already read the thread by JerryL, I quite liked the IQ of the shots posted,which is what prompted me to order the 70-300,although to be honest I was kinda hoping I could use use my Nikon tc,alas 'tis not to be.Then after reading the other threads on this subject (cheers guys)next on the agenda will be a Kenko 1.4 or Siggy 1.4.
