own the Tamron are around a month on an EOS 50D. After extensive photo tours I am absolutely thrilled.
Have before the Canon 70-300is obsessed USM. Repent to switch any second. Image results are clear
better. Higher resolution and sharpness, color and contrast very well and a really good image stabilizer!
Actually was already everything written. Who wants to buy a really good telephoto without spending a fortune
lies with the Tamron exactly spot on. 5years warranty after registration at Tamron are still in the process.
And please do not always compare the same with Canon L lenses ... is unfair ... knows probably everyone !!!
