Your Upcoming Review of New Tamron 150-600

[bmpress]

Bob,

This lens sounds exciting to me, but in assessing its benefit, would you be so kind to compare the IQ to both the Canon 100-400L and the Canon Powershot SX50 HS. I have both of these lenses and am pleased with the little camera's shots at 600mm and would love to see how they compare to the Tamron.

The SX50 I can do, but I don't have a 100-400L. I will compare it with the 300/4L and 500/4.5L, and maybe the Tamron 70-300.
