Mine arrived yesterday and my initial impression is that It's well worth the money. It handles well and fits nicely on the 70d. Really big lenses dont match well with a smaller body like that but this one seems just right.The IQ is what I expected, really good to 400 and good to 600 same thing for the af. I think the sigma 120-300 with the canon tc's is still better but this lens is 1/2 the weight and less than 1/3rd the price (1/4th if you add the cost of the converters) if you are looking for a packable high quality long zoom with an attractive price then I don't see how you could do much better, I am very pleased so far.
...are you saying that the Sigma 120-300 is better than the tamron at 600 ie 600/5.6 - or 600/8?
If so that surprises me because the photographylife tests of the Sigma at 600/5.6 were quite poor and only slightly better at 600/8.
