But i took it out today for some wildlife shots, and WOW this thing is nothing short of amazing.

I just recv'd this lens and it doesn't even mount on my Sony Alpha SLT-A65 DSLR Digital Camera .. so sad to not get the right thing - Very disappointed

The one best thing I could easily see in comparison to the 100-400 is the contrast, a very beautiful contrast and color reproduction

It may not be the most wonderful thing out

I love this thing!!!

I can not say enough positive things about this lens!!!

I love these lenses and have nothing but good things to say about them, but I needed more reach.

Fast delivery and every thing I expected.

Everything they say about good thing to this lens are true, i love it and I am enjoying the outcome of this lens.

This thing produces very sharp

No as sharp I like it
