Thanks for sharing the images ... from whatever I read/saw so far, I am very impressed with the Tamron ... the fact that people are actually comparing it with lenses that cost far more, speaks volumes for the Tamron which costs just a little over $1000 ... looks like the third party manufacturers (especially Sigma & Tamron) have really stepped up their game. After the announcement of this Tamron lens, Nikon has recently dropped the price of their newest 80-400 VR II lens by $400.
I reckon that Sigma will drop the price of their 120-300/2.8 as well in due course.
Also second hand prices of Can/Nik 300/2.8 IS/VR should take a hit.
May even affect the pricing of a new 100-400/5.6 if it ever gets born. That would be good! It would serve Canon right for p*****g everybody off by keeping shtum about it.
Looking forward to see a photozone or photographylife detailed review of this great Tamron.
