For the Tamron G2 I haven't found prices or MTF

$1299 for the Tamron G2

So it's only the MTFs missing. I guess it will be a bit better than Sigma's but also not "outperform" the Nikkor. Actually, the Sigma appears to be a bit better in the center of it's Tele-position?

MTF charts yadda yadda... and look at what Markus has found in his review of that Nikkor!
