Q: 6. Would this hold a Sigma 150-600mm lens?

A: There are different models of Sigma zoom lenses that are 150-600mm, so it's impossible to give a single definitive answer to your question. As such, we'll just say that even the longest of the compartments of the Lowepro Powder Backpack 500 AW (Gray and Orange) (B&H# LOP500AWGO) is about the same length as the Sigma 150-600mm f/5-6.3 DG OS HSM Contemporary Lens for Canon EF (B&H# SI1506005CC) which is the most popular Sigma 150-600mm that we sell. Moreover, it would be so tight a fit with the newer Sigma 150-600mm f/5-6.3 DG DN OS Sports Lens for Sony E (B&H #SI150600SE) (also available for L mount cameras) that you may not consider it a good fit at all. In the cases of at least those two especially popular Sigma 150-600mm lenses it is clear that neither will fit while attached to any camera.
