Sigma 150-600 Sport

IMHO, just shoot with it. If it delivers the goods then enjoy it. If it doesn't then flip it and get something else.

Thanks Dave. That, of course, is the plan, enjoy what you have and shoot until you identify a need. I am not usually an early adopter, so, in a way, I am just going back and making my normal assessments after the fact to make sure I have the lens that best fits my kit and understanding the pros/cons of my lenses.

For example, for any of those interested, I've also played with the "actual" focal lengths based on Bryan's reported distance to his target on the spec page.

Sigma:
@400 mm = 405
@500 mm = 494
@600 mm = 575

100-400II:
@400 mm = 392
@560 mm = 532
