That I understand, it was not my purpose to put it straight against the Tamron, which is a super zoom for APS-C and not a telezoom for FF that the Sigma is. Like I said, "in another galaxy" :lol:  

 

I only wanted to point out that the Sigma indeed is a nice lens, light and good enough in it's class. I was not expecting that performance. I didn't want to say "those lenses can't be compared".
