I want to see how it compares to the Sigma 50-500 OS, this is wide open at 500mm. I might miss the 50-150 range though, I do use that sometimes. I also use the macro capability of the Sigma.
Yeah, I think the 50-500 is the main competition of this lens, and I really like the 50-500. I've rented one a couple of different times and taken probably 3000 shots total with it. Not all have been good images, but if I do my part, it will do its job very well. I hope the Tamron does the same.
