My English is not sufficient to decipher the meaning of that sentence. When I put it in DeepL, it is translated to German and tells me "Also bedeutet "a" Tamron oder Sigma 150-600mm nur die besten 2? Nur um das klarzustellen." The last sentence was easy, the first .... 

 

The point is, "a" Tamron or Sigma 150-600 means AFAIK all of them - including the older Tamron (and, I thought at that moment, an older Sigma - but that was a 150-500 :wacko: ).
