Tamron 28-300 on 6D
I had 60d with 17-55 and very happy with it, but I still have the 18-200 for class field trip with my kids or similiar situation when I don't have time to switch lens. Given my need, does anyone use the Tamron 28-300 on the 6d and happy with it? I know, why buy 6D and asking about the Tamron, but I find for the environment I explain above, I need the superzoom. BTW, I am currently using the 25-70mkII and 24-105 as the "super zoom" but if the Tamron are closer to the 24-105, then I rather buy that lens. Thanks for any input!
