personally now that you have introduced me to the 24-70 f2.8 , I think i am going to get the tamron at such a good price .
plus if you are from the states i bet you would get your money back if you wanted to upgrade , if the tamron is more expensive there .
I don't think there would be a problem with vignetting as you will be using more the center of the lens .
Unless you are thinking of going FF in the future , which i am not .
I pressed the go button last night so we shall see later today what the lens really looks like - with amazon, at least it can go back easily if all is not well.
to others who responded, many thanks for the helpful input. The driver in the end that made me decide on trying the Tamron was the VC and the fact the Sigma did not do as well as the other three in the head to head run by nikonguy (the utube sessions) and, given the UK pricing, the Sigma's advantage over the Tamron goes away.
